<s>[INST] In class, the teacher asked a question and only one student answered the question. If 80% of the students in the class answered correctly, the number of students who answered the question is 80. It says that 80% of the students in the class answered the question. However, I think there is an ambiguity here. 
Is the correct interpretation that 80% of the students answered the question and all of them answered it correctly, or is it that 80% of the students who answered the question answered it correctly?[/INST]
