Question 1. To support the main conclusion of the passage as a whole, each paragraph in the passage
A. mentions the views of authorities presumed to have studied how CEOs can affect corporate performance
B. presents a factor that allegedly influences how CEOs are viewed by their corporations’ employees
C. describes circumstances under which CEOs can have a significant effect on employee performance
D. discusses one or more elements of corporate structure that determines the degree to which CEOs can affect corporate performance
E. illustrates how CEO compensation can create counterproductive incentives within corporations
The problem with this question is that it wants to know about what is common in this passage in each paragraph and when first reading the passage, we see that some aspects of CEOs are analysed and different results from studies are presented. Now, if one reads question A, that talks about
authorities, one will most likely discard this answer choice if one does not read the answer choice until the end. After all, we are looking for some sort of critique that is mentioned in all 2 paragraphs. Reading choice D superficially, one is inclined to choose it. For one, it doesn't talk about authorities

and then the abilities of the CEO are questioned. However, looking at A more thoroughly, we see that it talks about
authorities that have studied something. What exactly: how CEOs can affect corporate performance. Choice D on the other hand is wrong as there is a specific mentioned that is only present in 2nd paragraph: one or more elements of corporate structure. If one would have read the passage actively and defined at the beginning the functions of each paragraph, choice D would not have been that attractive.
This is a common trick that I encounter when solving tougher GMAT verbal passages. We usually have a specific definition for the word authority, that defines authority as people with power. The other definition is to be an authority in a specific field. If one only considers the first meaning, chance are high that the choice will be discarded. Happened to me.
