Which sentence best introduces a chart describing changes over a period?

• A. The chart shows changes in the figures for X between year A and year B, including alterations to roads and buildings.
• B. The chart presents population data for X area across several years.
• C. The chart compares climate data for several regions.
• D. The chart summarizes economic indicators for X region.

Answer: (A)

The key idea being tested is how to open a chart that shows changes over time with a clear time frame and the elements that changed. The sentence that states the chart shows changes in the figures for X between year A and year B, including alterations to roads and buildings, does this best. It immediately signals what is changing (the figures for X), the period over which changes are occurring (between year A and year B), and gives a concrete hint about what kinds of changes to discuss (roads and buildings). This framing prepares you to describe trends and specific shifts in the data. Other options miss that explicit focus on change over a defined period. One option mentions data across several years without stressing changes, which can lead to a more static start. The remaining options talk about comparisons or summaries without tying the intro to changes over time, so they don’t set up the same clear narrative for a Task 1 description.
