Wrong answer to problems

[WesleyHsieh0806]

The answers to several problems seem incorrect, I guess some info are missing for the question?

For example, the below is Problem 950:

question 950: The slope of f(x) at x=0 is ____
answer: positive
choices: ['positive', 'negative', 'zero', 'undefined']

First, the function in the image is g(x) not f(x). Second, even if g(x) = f(x), the slope should be negative. The relation between g(x) and f(x) is probably missing, e.g., g'(x) = f(x)?

Thanks for your feedback!

Despite our efforts in reviewing the benchmark multiple times, it's inevitable that a small number of examples may contain incorrect or ambiguous information. Considering the need for consistent evaluations, we've decided to retain these examples in the current version. However, we are planning to release a new version to correct the errors identified.
