TEST 1
READING PASSAGE 1
Our conception of time depends on the way we
measure it.
A
According to archaeological evidence, at least 5,000
years ago, and long before the advent of the
Roman Empire, the Babylonians began to measure
time, introducing calendars to co-ordinate
communal activities, to plan the shipment of goods
and, in particular, to regulate planting and
harvesting. They based their calendars on three
natural cycles: the solar day, marked by the
successive periods of light and darkness as the
earth rotates on its axis; the lunar month, following
the phases of the moon as it orbits the earth; and
chronicle = a written record, history, story of
historical events.
timekeeping = the activity of recording the
time something takes
advent = coming, start, arrival, the time when
something first begins to be widely used.
co-ordinate = organize, manage, direct, o t
make various, separate things work together.
communal = shared, common, public,
relating or belonging to all the people living in
a particular.
regulate= control, adjust, standardize.
solar = relating to the Sun
axis = alignment, centre line, (the imaginary
line around which a large round object, such
as the Earth).
lunar = relating to the Moon.
orbit = circle, revolve around, travel around,
go around,

the solar year, defined by the changing seasons that
accompany our planet's revolution around the sun.
B
Before the invention of artificial light, the moon had
greater social impact. And, for those living near the
equator in particular, its waxing and waning was
more conspicuous than the passing of the
seasons. Hence, the calendars that were developed
at the lower latitudes were influenced more by the
lunar cycle than by the solar year. In more northern
climes, however, where seasonal agriculture was
practised, the solar year became more crucial. As
the Roman Empire expanded northward, it
organised its activity chart for the most part around
the solar year.
C
Centuries before the Roman Empire, the Egyptians
had formulated a municipal calendar having 12
months of 30 days, with five days added to
approximate the solar year. Each period of ten days
was marked by the appearance of special groups of
stars called decans. At the rise of the star Sirius just
before sunrise, which occurred around the all-
important annual flooding of the Nile, 12 decans
could be seen spanning the heavens. The cosmic
significance the Egyptians placed in the 12 decans
led them to develop a system in which each interval
of darkness (and later, each interval of daylight) was
divided into a dozen equal parts. These periods
became known as temporal hours because their
duration varied according to the changing length of
days and nights with the passing of the seasons.
Summer hours were long, winter ones short; only at
the spring and autumn equinoxes were the hours of
daylight and darkness equal. Temporal hours, which
were first adopted by the Greeks and then the
Romans, who disseminated them through Europe,
remained in use for more than 2,500 years.
D
In order to temporal hours during the day, track
inventors created sundials, which indicate time by
the length or direction of the sun's shadow. The
accompany= go together with, come with, be
associated with, happen with, appear with.
artificial= man-made, synthetic, non-natural.
equator = an imaginary line drawn around
the middle of the Earth.
wax and wane = to increase and decrease
over time.
conspicuous = obvious, clear, noticeable.
latitude = the distance north or south of the
equator, measured in degrees.
clime = zone, region, a place that has a
particular type of climate.
crucial = vital, fundamental, essential,
important, necessary, key.
formulate = invent, create, make, develop.
municipal = civic, public, community,
#private.
decans = The decans (Egyptian) are 36
groups of stars (small constellations) used in
the Ancient Egyptian astronomy.
cosmic = relating to space or the universe.
interval= intermission, interlude, break.
temporal hours = a unit of time used in the
past that divided the daylight into an equal
number of hours,
duration = the length of time that something
lasts.
equinox = solstice one of the two times in a ,
year when night and day are of equal length.
adopt = accept, approve, implement, apply,
#reject
disseminate = spread, publish, distribute.
track = follow, trace, pursue.
sundial = an object used in the past for
telling the time.

sundial's counterpart, the water clock, was
designed to measure temporal hours at night. One
of the first water clocks was a basin with a small
hole near the bottom through which the water
dripped out. The falling water level denoted the
passing hour as it dipped below hour lines
inscribed on the inner surface. Although these
devices performed satisfactorily around the
Mediterranean, they could not always be depended
on in the cloudy and often freezing weather of
northern Europe.
E
The advent of the mechanical clock meant that
although it could be adjusted to maintain temporal
hours, it was naturally suited to keeping equal ones.
With these, however, arose the question of when to
begin counting, and so, in the early 14th century, a
number of systems evolved. The schemes that
divided the day into 24 equal parts varied according
to the start of the count: Italian hours began at
sunset, Babylonian hours at sunrise, astronomical
hours at midday and 'great clock' hours, used for
some large public clocks in Germany, at midnight.
Eventually these were superseded by 'small clock',
or French, hours, which split the day into two 12-
hour periods commencing at midnight.
F
The earliest recorded weight-driven mechanical
clock was built in 1283 in Bedfordshire in England.
The revolutionary aspect of this new timekeeper was
neither the descending weight that provided its
motive force nor the gear wheels (which had been
around for at least 1,300 years) that transferred the
power; It was the part called the escapement. In the
early 1400s came the invention of the coiled spring
or fusee which maintained constant force to the gear
wheels of the timekeeper despite the changing
tension of its mainspring. By the 16th century, a
pendulum clock had been devised, but the
pendulum swung in a large arc and thus was not
very efficient.
counterpart = equal, colleague, equivalent.
drip = drop, come out, leak, #stream.
denote = indicate, represent, refer to,
#connote
dip = dunk, immerse, to put something into a
liquid for a very short time and take it out
again.

the bottom that swings regularly from side to
side to control the working of a clock.

G
To address this, a variation on the original
escapement was invented in 1670, in England. It
was called the anchor escapement, which was a
lever-based device shaped like a ship's anchor. The
motion of a pendulum rocks this device so that it
catches and then releases each tooth of the escape
wheel, in turn allowing it to turn a precise amount.
Unlike the original form used in early pendulum
clocks, the anchor escapement permitted the
pendulum to travel in a very small arc. Moreover,
this invention allowed the use of a long pendulum
which could beat once a second and thus led to the
development of a new floor standing case design,
which became known as the grandfather clock.
H
Today, highly timekeeping instruments set accurate
the beat for most electronic devices. Nearly all
computers contain a quartz-crystal clock to
regulate their operation. Moreover, not only do time
signals beamed down from Global Positioning
System satellites calibrate the functions of
precision navigation equipment, they do so as well
for mobile phones, instant stock-trading systems
and nationwide power-distribution grids. So integral
have these time-based technologies become to day-
to-day existence that our dependency on them is
recognised only when they fail to work.

An accident that occurred in the skies over the
Grand Canyon in 1956 resulted in the
establishment of the Federal Aviation Administration
(FAA) to regulate and oversee the operation of aircraft
in the skies over the United States, which were
becoming quite congested. The resulting structure of air
traffic control has greatly increased the safety of flight in
the United States, and similar air traffic control
procedures are also in place over much of the rest of

B
Rudimentary air traffic control (ATC) existed well before
the Grand Canyon disaster. As early as the 1920s, the
earliest air traffic controllers manually guided aircraft in
the vicinity of the airports, using lights and flags, while
beacons and flashing lights were placed along cross-
country routes to establish the earliest airways.
However, this purely visual system was useless in bad
weather, and, by the 1930s, radio communication was

coming into use for ATC. The first region to have
something approximating today9s ATC was New York
City, with other major metropolitan areas following
soon after.
C
In the 1940s, ATC centres could and did take advantage
of the newly developed radar and improved radio
communication brought about by the Second World
War, but the system remained rudimentary. It was only
after the creation of the FAA that full-scale regulation of
America9s airspace took place, and this was fortuitous,
for the advent of the jet engine suddenly resulted in a
large number of very fast planes, reducing pilots9
margin of error and practically demanding some set of
rules to keep everyone well separated and operating
safely in the air.
D
Many people think that ATC consists of a row of
controllers sitting in front of their radar screens at the
nation9s airports, telling arriving and departing traffic
what to do. This is a very incomplete part of the picture.
The FAA realised that the airspace over the United
States would at any time have many different kinds of
planes, flying for many different purposes, in a variety of
weather conditions, and the same kind of structure was
needed to accommodate all of them.
E
To meet this challenge, the following elements were put
into effect. First, ATC extends over virtually the entire
United States. In general, from 365m above the ground
and higher, the entire country is blanketed by controlled
airspace. In certain areas, mainly near airports,
controlled airspace extends down to 215m above the
ground, and, in the immediate vicinity of an airport, all
the way down to the surface. Controlled airspace is that
airspace in which FAA regulations apply. Elsewhere, in
uncontrolled airspace, pilots are bound by fewer
regulations. In this way, the recreational pilot who
simply wishes to go flying for a while without all the
restrictions imposed by the FAA has only to stay in
uncontrolled airspace, below 365m, while the pilot who
does want the protection by ATC can easily afforded
enter the controlled airspace.
F
The FAA then recognised two types of operating
environments. In good meteorological conditions, flying

regulation = control, guideline,
adjustment, rule.
fortuitous = lucky, fortunate, miraculous.

margin of error = the degree to which
a calculation might or can be wrong

happen

thick layer.

good/great time, a blast, entertainment,
relaxation, leisure.

would be permitted under Visual Flight Rules (VFR),
which suggests a strong reliance on visual cues to
maintain an acceptable level of safety. Poor visibility
necessitated a set of Instrumental Flight Rules (IFR),
under which the pilot relied on altitude and
navigational information provided by the plane9s
instrument panel to fly safely. On a clear day, a pilot in
controlled airspace can choose a VFR or IFR flight plan,
and the FAA regulations were devised in a way which
accommodates both VFR and IFR operations in the
same airspace. However, a pilot can only choose to fly
IFR if they possess an instrument rating which is above
and beyond the basic pilot9s license that must also be
held.
G
Controlled airspace is divided into several different
types, designated by letters of the alphabet.
Uncontrolled airspace is designated Class F, while
controlled airspace below 5,490m above sea level and
not in the vicinity of an airport is Class E. All airspace
above 5,490m is designated Class A. The reason for the
division of Class E and Class A airspace stems from
the type of planes operating in them. Generally, Class E
airspace is where one finds general aviation aircraft (few
of which can climb above 5,490m anyway), and
commercial turboprop aircraft. Above 5,490m is the
realm of the heavy jets, since jet engines operate more
efficiently at higher altitudes. The difference between
Class E and A airspace is that in Class A, all operations
are IFR, and pilots must be instrument-rated, that is,
skilled and licensed in aircraft instrumentation. This is
because ATC control of the entire space is essential.
Three other types of airspace, Classes D, C and B,
govern the vicinity of airports. These correspond
roughly to small municipal, medium-sized metropolitan
and major metropolitan airports respectively, and
encompass an increasingly rigorous set of regulations.
For example, all a VFR pilot has to do to enter Class C
airspace is establish two-way radio contact with ATC.
No explicit permission from ATC to enter is needed,
although the pilot must continue to obey all regulations
governing VFR flight. To enter Class B airspace, such
as on approach to a major metropolitan airport, an
explicit ATC clearance is required. The private pilot who
cruises without permission into this airspace risks losing
their license.
reliance = dependence, rely on, hinge

necessitate = essential, require, need,

Can human beings communicate by thought alone?
For more than a century the issue of telepathy has
divided the scientific community, and even today it still
sparks bitter controversy among top academics.
Since the 1970s, parapsychologists at leading
universities and research institutes around the world
have risked the derision of sceptical colleagues by
putting the various claims for telepathy to the test in
dozens of rigorous scientific studies. The results and
their implications are dividing even the researchers
who uncovered them.

Some researchers say the results constitute
compelling evidence that telepathy is genuine. Other
parapsychologists believe the field is on the brink of
collapse, having tried to produce definitive scientific
proof and failed. Sceptics and advocates alike do
concur on one issue, however: that the most impressive
evidence so far has come from the so-called 'ganzfeld'
experiments, a German term that means 'whole field'.
Reports of telepathic experiences had by people during
meditation led parapsychologists to suspect that
telepathy might involve 'signals' passing between people
that were so faint that they were usually swamped by
normal brain activity. In this case, such signals might be
more easily detected by those experiencing meditation-
like tranquility in a relaxing 'whole field' of light, sound
and warmth.
The ganzfeld experiment tries to recreate these
conditions with participants sitting in soft reclining
chairs in a sealed room, listening to relaxing sounds
while their eyes are covered with special filters letting in
only soft pink light. In early ganzfeld experiments, the
telepathy test involved identification of a picture
chosen from a random selection of four taken from a
large image bank. The idea was that a person acting as
a 'sender' would attempt to beam the image over to the

effect, but one which statistical tests suggested could
not be put down to chance.
The implication was that the ganzfeld method had
revealed real evidence for telepathy. But there was a
crucial flaw in this argument - one routinely overlooked
in more conventional areas of science. Just because
chance had been ruled out as an explanation did not
prove telepathy must exist; there were many other ways
of getting positive results. These ranged from 'sensory
leakage' - where clues about the pictures accidentally
reach the receiver - to outright fraud. In response, the
researchers issued a review of all the ganzfeld studies
done up to 1985 to show that 80 per cent had found
statistically significant evidence. However, they also
agreed that there were still too many problems in the
experiments which could lead to positive results, and
they drew up a list demanding new standards for future
research.
After this, many researchers switched to autoganzfeld
tests - an automated variant of the technique which used
computers to perform many of the key tasks such as the
random selection of images. By minimising human
involvement, the idea was to minimise the risk of
flawed results. In 1987, results from hundreds of
autoganzfeld tests were studied by Honorton in a 'meta-
analysis', a statistical technique for finding the overall
results from a set of studies. Though less compelling
than before, the outcome was still impressive.
Yet some parapsychologists remain disturbed by the
lack of consistency between individual ganzfeld
studies. Defenders of telepathy point out that
demanding impressive evidence from every study
ignores one basic statistical fact: it takes large samples
to detect small effects. If, as current results suggest,
telepathy produces hit-rates only marginally above the
25 per cent expected by chance, it's unlikely to be
detected by a typical ganzfeld study involving around 40
people: the group is just not big enough. Only when
many studies are combined in a meta-analysis will the
faint signal of telepathy really become apparent. And
that is what researchers do seem to be finding.

What they are certainly not finding, however, is any
change in attitude of mainstream scientists: most still
totally reject the very idea of telepathy. The problem
stems at least in part from the lack of any plausible
mechanism for telepathy.
Various theories have been put forward, many focusing
on ideas from theoretical physics. They include esoteric
'quantum entanglement', in which events affecting one
group of atoms instantly affect another group, no matter
how far apart they may be. While physicists have
demonstrated entanglement with specially prepared
atoms, no-one knows if it also exists between atoms
making up human minds. Answering such questions
would transform parapsychology. This has prompted
some researchers to argue that the future lies not in
collecting more evidence for telepathy, but in probing
possible mechanisms. Some work has begun already,
with researchers trying to identify people who are
particularly successful in autoganzfeld trials. Early
results show that creative and artistic people do much
better than average: in one study at the University of
Edinburgh, musicians achieved a hit-rate of 56 per cent.
Perhaps more tests like these will eventually give the
researchers the evidence they are seeking and
strengthen the case for the existence of telepathy.

Nevertheless, demand for flat glass was very high
and glassmakers across the world were looking for a
method of making it continuously. The first
continuous ribbon process involved squeezing
molten glass through two hot rollers, similar to an old
mangle. This allowed glass of virtually any thickness
to be made , but the rollers would leave non-stop
both sides of the glass marked, and these would then
need to be ground and polished. This part of the
process rubbed away around 20 per cent of the
glass, and the machines were very expensive.
The float process for making flat glass was invented
by Alistair Pilkington. This process allows the
manufacture of clear, tinted and glass for coated
buildings, and clear and tinted glass for vehicles.
Pilkington had been experimenting with improving the
melting process, and in 1952 he had the idea of using
a bed of molten metal to form the flat glass,
eliminating altogether the need for rollers within the
float bath. The metal had to melt at a temperature
less than the hardening point of glass (about 600°C),
but could not boil at a temperature below the
temperature of the molten glass (about 1500°C). The
best metal for the job was tin.
The rest of the concept relied on gravity, which
guaranteed that the surface of the molten metal was
perfectly flat and horizontal. Consequently, when
pouring molten glass onto the molten tin, the
underside of the glass would also be perfectly flat. If
the glass were kept hot enough, it would flow over the
molten tin until the top surface was also flat,
horizontal and perfectly parallel to the bottom
surface. Once the glass cooled to 604°C or less it
was too hard to mark and could be transported out of
the cooling zone by rollers. The glass settled to a
thickness of six millimetres because of surface
tension interactions between the glass and the tin.
By fortunate coincidence, 60 per cent of the flat
glass market at that time was for six-millimetre glass.
Pilkington built a pilot plant in 1953 and by 1955 he
had convinced his company to build a full-scale

plant. However, it took 14 months of non-stop
production, costing the company £100,000 a month,
before the plant produced any usable glass.
Furthermore, once they succeeded in making
marketable flat glass, the machine was turned off for
a service to prepare it for years of continuous
production. When it started up again it took another
four months to get the process right again. They
finally succeeded in 1959 and there are now float
plants all over the world, with each able to produce
around 1000 tons of glass every day, non-stop for
around 15 years.
Float plants today make glass of near optical quality.
Several processes - melting, refining,
homogenising - take place simultaneously in the
2000 tonnes of molten glass in the . They furnace
occur in separate zones in a complex glass flow
driven by high temperatures. It adds up to a
continuous melting process, lasting as long as 50
hours, that delivers glass smoothly and continuously
to the float bath, and from there to a coating zone and
finally a heat treatment zone, where stresses formed
during cooling are relieved.
The principle of float glass is unchanged since the
1950s. However, the product has changed
dramatically, from a single thickness of 6.8 mm to a
range from sub-millimetre to 25 mm, from a ribbon
frequently marred by inclusions and bubbles to
almost optical perfection. To ensure the highest
quality, inspection takes place at every stage.
Occasionally, a bubble is not removed during refining,
a sand grain refuses to melt, a tremor in the tin puts
ripples into the glass ribbon. Automated on-line
inspection does two things. Firstly, it reveals process
faults upstream that can be corrected. Inspection
technology allows more than 100 million
measurements a second to be made across the
ribbon, locating flaws the unaided eye would be
unable to see. Secondly, it enables computers
downstream to steer cutters around flaws.
