Answer :
D. The sentence which best states the controlling idea of this passage is "The wire taps were never a secret, but they helped the United States gain military intelligence.
"
The following excerpts from the passage reaffirm this controlling idea :
1. "On balance, however, some valuable information was gathered from the tapped conversations. The U.S. learned, for example, a great deal about the Soviet and Eastern European order of battle, or its military organization. Others feel that the intelligence was valuable to check against similar information obtained from other sources."
2."The evidence suggests that the CIA gained two invaluable and untainted kinds of knowledge from the taps. The agency learned a basic blueprint of the Soviet and East German security systems, and it never picked up a glimmer of warning that Moscow intended to go to war.”
The correct answer for the question that is being presented above is this one: "editing and proofreading." The stage in which you polish your writing and fix errors is the stage of editing and proofreading. At this stage, everything has to be serious and be done diligently because whatever the output of this stage will tell you the final output.
A reversible fabric of linen, silk, cotton, or wool, woven with patterns.
The correct answer is "elevated style".
This is because all of the other options do not belong to a true epic, and fit more with a satire. A true epic is supposed to be serious and present a great deed by the main hero or the heroes.
Study of technology, people, organizations and their relation to each other.
