Series comparison Numerical Reasoning Question

Identify the correct series first, then compute the change on that series alone: (end − start) ÷ start. The correct answer is 33. Traps to avoid: 56 comes from the "read series a only" error; 79 comes from the "added the series" error; 23 comes from the "read series b only" error; 48 comes from the "wrong year" error.
