A Correct answer
Explanation

Initial rate = 2000/10 = 200 questions/day. After 6 days, 1200 questions are done, leaving 800. To finish 800 in 1 day, the new rate must be 800 questions/day. The increase is (800 - 200) / 200 = 600 / 200 = 300%.

AI explanation

The team's initial rate is 2000 questions in 10 days, meaning they develop 200 questions per day. After 6 days, they have completed 1200 questions, leaving 800 questions to be developed. To finish the remaining 800 questions in 1 day, the new required rate is 800 questions per day. The increase in rate is 800 - 200 = 600 questions per day, so the percentage increase needed is (600 / 200) * 100 = 300%.
