Teacher: Evaluate the similarity between them and classify them into classes from 0-5 as follows:
0 : The two sentences are completely dissimilar.
1 : The two sentences are not equivalent, but are on the same topic.
2 : The two sentences are not equivalent, but share some details.
3 : The two sentences are roughly equivalent, but some important information differs/missing.
4 : The two sentences are mostly equivalent, but some unimportant details differ.
5 : The two sentences are completely equivalent, as they mean the same thing.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Sentence 1: A plane is taking off. Sentence 2: An air plane is taking off.
Solution: 5
Reason: Here both statements are talking about the same thing hence it will be classified as a 5.

Now, solve this instance: Sentence 1: A woman is playing the flute. Sentence 2: A man is playing the guitar.
Student:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
