Why is E correct?

Could someone explain this question to me? Thanks!

@Shiyi-Zhang, Happy to help. The question says, "According to the passage, Wagner asserts which one of the following about the roles of architect and engineer?" This question wants us to select the answer choice that accurately captures the statement Wagner makes about the roles of architect and engineer. We'll likely be choosing an answer that has explicit support from the text, so let's take a look at the part of the passage where Wagner is discussing the roles of architect and engineer. In the passage, Wagner discusses the roles of architect and engineer in the third paragraph, where he states that "the architect must learn as a rule to be an engineer" (lines 37 to 38). Then, the author of the passage delves more into detail about this view, mentioning that Wagner claimed that the architect has to develop the skills that an engineer has (lines 33 to 34). In looking at the answer choices, (E) says, "The architect should acquire the knowledge of technical matters typically held by the engineer." We have explicit support for this answer choice in lines 33 and 34 since Wagner says that the architect needs to develop the skills that an engineer has. Does this make sense? Let us know if you have any more questions!
