The graph below shows the annual revenue for Company P and Company Q from 2018 to 2022. In which year was the absolute difference in revenue between Company P and Company Q the greatest? (Assume a line graph showing two lines, one for Company P and one for Company Q, with revenue on the Y-axis and years 2018-2022 on the X-axis. The lines diverge significantly in 2022, with P at $70M and Q at $20M for example.)

The correct answer to the question "The graph below shows the annual revenue for Company P and Company Q from 2018 to 2022. In which year was the absolute difference in revenue between Company P and Company Q the greatest? (Assume a line graph showing two lines, one for Company P and one for Company Q, with revenue on the Y-axis and years 2018-2022 on the X-axis. The lines diverge significantly in 2022, with P at $70M and Q at $20M for example.)" is Option D: 2022.

The other options — A) 2018, B) 2019, C) 2021 — are incorrect for this GMAT Exam Prep question. As explained above: By visually inspecting a typical line graph where P and Q's revenues are plotted, the largest vertical gap between the lines, representing the absolute difference, would be observed at the year 2022,…
