After multiple attempts at GMAT, I have understood the importance of discarding options so that we are left with very few options to select as an answer.
Lets go through each question and its options.
1. Which of the following, if true, would most strongly support the assumption rejected by the argument of the passage?
To simplify - Something that supports an assumption rejected by the passage should be the answer. Also, assumption is never stated in the passage.
(A) The gods pursue their agendas by conferring with other gods to ensure that their agendas serve a common goal.
This supports the assumption that gods worked in tandem to accomplish their goals. This assumption is rejected because 'each one acting within certain boundaries to accomplish his or her own agenda. As such, the wills of the gods do not coincide to allow for the formulation of a cohesive “master plan"'.
(B) The agendas of gods and mortals frequently coincide with the demands of fate.
Yes, this supports the assumption accepted by the passage - 'In The Odyssey and The Histories, the idea of gods with limited power leads to a conception of fate wherein the gods act not as the creators of destiny, but as agents of its fulfillment.'
(C) Homer and Herodotus disagree strongly about the motives and agendas of the gods, as well as about the nature and severity of their conflicts. No, where in the passage suggests that both the writers disagree. In fact '
These two works share two important motifs:' shows they agree with each other to some extent.
(D) Destiny would be fulfilled regardless of what activities gods and mortals engaged in. -
This supports the assumption accepted by the passage - already stated in the passage 'Instead of destiny created by the gods, Homer and Herodotus present fate as something beyond the gods—a driving force under which the actions of gods and mortals lead to the realization of destiny'.
(E) In both Homer and Herodotus, gods and mortals frequently examine their motives and goals and are capable of making their own decisions about what to do. -
This supports the assumption accepted by the passage - already stated in the passage 'each one acting within certain boundaries to accomplish his or her own agenda'.
So, answer is A.
