First with Question 4: Why did we diagram answer choice C as EP some SP, and not EP & A some SP, since we have "who are" in the statement. I remember on previous questions in the S & N lesson, A who is B is C was diagrammed as A & B -> C.
About Question 5: Why did we diagram the phrase in the second sentence, "the interest from some interest-bearing accounts" the same as the phrase in the first sentence "interest-bearing accounts"? I first thought them to be different conditions, one is about the type of account, and the other is about interest itself.
Finally, Question 6: My attempt to diagram the passage was a complete mess. The main reason was that I did not see that the sentences in the passage were repetitive (rephrased). My final attempt treated the first and second sentences as one, since the people referred to in the second sentence were the same as those in the first sentence. Thus I diagrammed it as follows: People who invest - most - don't do research (i.e., rely on a broker or depend on hunches). Accordingly, I concluded that answer choice B was a paraphrase of these two sentences and the correct answer.
