Description
This pull request addresses issue #33 by fixing the regular expression used to extract answers from model outputs with MMLU.
Solution
The existing regex fails to handle cases where the "Answer: LETTER" pattern appears multiple times. This is resolved by:
re.findall: Instead ofre.search,re.findallis used to find all occurrences of the answer pattern.re.findallresults is taken as the correct answer.
