I thought the main conclusion was the first sentence: "The way science is conducted and regulated can be changed." So this definitely disoriented my answer selection immensely.

Quick Note!

Look at the keywords answer choices e and b are using. E gives us information that is technically true, but it's not relevant! The keyword "some" in e could be any variation from 1 to all. But the keyword "most" in answer choice b significantly weakens the argument by implying that the majority of success isn't coming from the contents of the program, but from the prior educational experience of the parents!
