Passage B
It has long been known that underweight, premature babies develop into children who perform worse at
school than children who had normal birth weight and were full-term. A recent study examining the effects
of birth weight on intelligence suggests that even among full-term babies the heavier ones have an
advantage. The study has been following 3,900 British men and women since their birth in 1946. Birth
weight was correlated with scores on tests of reading and arithmetic skills, non-verbal reasoning, memory,
speed, and concentration. These tests were conducted when the participants were 8, 11, 15, 26, and 43
years old. Generally speaking, the heavier children performed better on the tests. The relationship was
strongest at age 8 and then weakened over time. By age 43, the relationship was negligible. The results
were not affected by birth order, gender, father’s social class, or mother’s education and age.
These findings must be interpreted with caution. First, the results were based on averages. Second, birth
weight is only one of numerous factors influencing cognitive function. Parental interest in education - such
as volunteering at school or helping with homework - may offset the effect of birth weight. Furthermore,
poor environmental conditions, such as living in an overcrowded home, breathing polluted air, or being
caught in a bitter divorce can diminish the early advantages enjoyed by heavier babies.
Although no one knows exactly what makes a newborn baby heavy, it is known that healthy, well-nourished
mothers tend to have heavier babies, while those who eat poorly, smoke, and are heavy drinkers tend to
produce smaller ones. There are probably several other variables that affect birth weight, but if and how
those are connected to intelligence is not known.
66. In this study, the researchers examined the relationship between _______.
A. maternal nutrition and birth weight
B. home environment and intelligence
C. age and intelligence
D. intelligence and birth weight
67. What did the researchers find out about the relationship they were studying?
A. It increased up to age 26, then decreased.
B. It remained steady until age 26, then decreased.
C. It decreased as the subjects grew older.
D. It remained steady throughout the study.
68. Which children have an advantage at school?
A. Those who were full-term, lighter weight babies.
B. Those who were premature but normal weight babies.
C. Those who were full-term, heavier babies.
D. Those who were premature babies who gained weight quickly.
69. According to the passage, what is one possible reason to question the conclusions of the study?
A. The study did not consider some environmental factors.
B. The study was done too long ago.
C. The study was done on premature babies, not full term ones.
