2) In 2010, cruise ships were chosen to be the accommodation of around 250 thousand individuals who traveled to this island.

Sample:
The line graph presents data on the number of travelers who went to a Caribbean island and stayed on two types of accommodation from 2010 to 2017.
Overall, the numbers of visitors choosing to stay on a cruise ship or the island had increased significantly throughout the period, resulting in a massive leap in the number of tourists visiting this location.
The number of tourists visiting this island and stayed on the it stabilized at around 750000 in the first two years before increasing to a peak of 1.5 million in 213,2014 and 2015. After experiencing a slight decrease of around 250000 in 2016, it markedly recovered (surged back) to the previous peak in the final year.
250000 visitors to this island decided to settle on cruise ships during their trips in 2010 before this type of accommodation gained its popularity a year later as the figure increased twofold. It then plunged back to the starting level in 2012.

3) Process

The diagram provides information about the steps that need to be taken to produce bricks.
Overall, the entire procedure consists of three main phases, including the extraction of raw materials and shaping the bricks, applying heat on them, and packaging and delivery.
The first step begins with the extraction of clay from the ground using a digger. This extracted clay is then sifted (sàng lọc) to ensure consistency as a metal grid breaks down clumps in the clay. Subsequently, the sifted clay is conveyed on a roller before being mixed with sand and water and taken on the shape of a brick using either a mould or a wire cutter.
A process of dehydration occurs in the next stage as the freshly shaped bricks loses their water content in a drying oven from one or two days. The dehydrated bricks are then heated in two different kilns. The first one applies a moderate level of heat, ranging from 200 to 980 degrees Celsius, while the second uses a much higher level from 870 to 1300 degrees Celsius. In the second kiln, the color of the bricks takes on a much brighter hue (màu sắc). After being heated, the bricks are then allowed to cool down in a cooling chamber from two to three days.
In the last stage, the bricks are then packaged into large prism (hình lập phương) blocks before being transported to consumers by a truck.

4) Map
One of the most remarkable changes in the map is that the playing fields have their sizes reduced to roughly 50%. This reduction allows the construction of a classrooms block, a pool, and a fitness center on the left side. On the right side, a new storey has been added to the existing block, while another block has been built closer to the playing fields.
