RC Question 4 Explanation

DISCUSSION: It helps to prephrase a little. Here, I tried to think of what I knew about passage A:

• It doesn’t cite science
• It’s less certain that passage B

This is actually enough to answer the question!

___________

1. Both passages are fairly certain that muscle memory exists. Passage A obviously mentions it directly. And, passage B says “pumping up is easier for people who have been buff before”. True, they don’t say “muscle memory” at this point, but this is exactly the same concept that passage A calls muscle memory. And, in lines 60-61, passage B does call the persistence of extra nuclei “muscle memory”.
2. This is false. Passage B’s explanation is extra nuclei, and passage A never mentions nuclei.
3. CORRECT. This is likely. Lines 1-4 show that the author of passage A believes that virtually no scientific publications have discussed muscle memory. And then their explanations are speculation.
    
   If the author had known about the study on mouse muscle nuclei, they probably would have mentioned it. Lines 1-4 show that the author clearly wanted to talk about science.
4. There’s no support for this. Passage A doesn’t mention nuclei, so we have no evidence the author has any opinion on them one way or another.
5. This is like D. We have no evidence for this, because the author of passage A didn’t mention cross-species experiments.
