The chart shows Country X’s import and export figures (in billions of dollars) from 2010 to 2020. The blue line represents imports, and the orange line represents exports. A trade surplus occurs when exports exceed imports, while a trade deficit occurs when imports exceed exports. The difference between exports and imports is referred to as the balance of trade.
From each drop-down menu, select the option that creates the most accurate statement based on the information provided.

Drop-down 1:
There’s no need to calculate percentage changes for every year. Notice that in 2010, the import figure was the lowest on the chart. The line from 2010 to 2011 is the steepest starting from the lowest base, which results in the greatest percentage increase. Although the increase from 2019 to 2020 is also steep, it starts from a higher base (the 2019 amount). Therefore, the greatest percentage increase in imports occurred during the period 2010–2011.
Drop-down 2:
To calculate the range of the trade balance, we need to find the difference between the highest trade balance and the lowest trade balance during the period. The highest trade balance occurred in 2018, equal to 2500 − 1700 = 800. The lowest trade balance occurred in 2011, equal to 1800 − 1700 = 100. Therefore, the range of the trade balance is 800 − 100 = 700.
For Q1 - We can easily eliminate other options and focus only on 2010-2011 & 2019 - 2020. Even if you feel less confident of directly eliminating, you can always take a minute extra and calculate. 2010-2011 & 2019 - 2020 is 400/1400 & 400/1800 respectively. Clear winner - 2010-2011.
For Q2 - You can instantly identify the lowest Trade Balance (when both Export and Import try to merge/ or are closest). For the upper limit, check those gaps wherein the Export and Import lines are farthest from each other. 2018 - Balance: 800; 2011 - Balance: 100. Range is 700.
I am a bit confused for highest % increase for period 2010 to 11 and 2019 to 20. Both have same slope. Can anyone explain pls?

You can compare just the slopes when the bases are the same. Here the increase of 400 is the same, however, bases for both are different. One base is 1400 while the other is 1800. Hence, the one with thr lower base will have a greater percentage increase.
