A expirement hoped it helped
The soldiers and the journalists that were writing about it were very close to the action. They wrote about their experiences. Moreover, the Vietnam literature has no “escape hatches” (meaning we don't have comic relief, no moments of romance, and scant emphasis on coming-of-age energy). The primary goal was to make us feel like we were there.
The correct answer is "the desire of wise men".
In her play "Frankenstein" (1823), Mary Shelley uses different syntactic strategies in order to put emphasis on certain information. For example, she could have written something like this: "within my grasp is the study and desire of the wisest men...".
Instead, she chose to present the information in a rhetorical way. She introduced the "wh" word "what" opening the window for the reader to question himself what is the meaning of "what"?
What is THAT THING that had been the study and desire of wisest men since the creation of the world? What did they want to know?
I don't know for problem 4 because we were not given the poems. However, problem 7 is the last option and problem 9 is the second option.
