Hello. You did not present the text to which this question refers, which makes it impossible for it to be answered. However, I will try to help you in the best possible way.
Special agents are encouraged to use a cyanide pill, if caught, so that it is impossible for them to reveal secret and crucial information about the institution for which they work. This is because, cyanide is a highly toxic agent for humans, and can cause death in a few minutes, if ingested. In that case, special agents place a cyanide pill inside the mouth, to chew quickly if caught. This causes them to die and prevents them from revealing important things if they are questioned. Therefore, to answer your question, you should look for this type of information in your text.
The correct answer is C. Repetition of a phrase for emphasis
Explanation:
Kennedy's speech on June 26 of 1963 referred to the situation of Berlin during that time as this was divided into west and east. Moreover, the west side was supported by capitalist countries, while the east country was supported by the communist countries, especially the Soviet Union.
In terms of rhetoric, in this speech, Kennedy uses multiple times the phrase "Let them come to Berlin" to convey the idea communism is negative and has had negative effects on Berlin. For example, in "There are some who say that communism is the wave of future. Let them come to Berlin" the phrases emphasize communism is not a positive form of government, and has had negative effects in the city, which also suggests this situation should end. Thus, the correct answer is C.

"O, never/Shall sun that morrow see!" means "The morning when Duncan leaves here will never come, because we're going to kill him tonight." "Your face, my thane, is as a book where men/May read strange matters" means "By looking at your face, everybody can see what you're thinking." The rest of the speech means "To fool everybody, you have to behave the way everybody expects you to behave. You have to make sure that the way you look, the way you act, and the way you talk all seem to be giving Duncan a friendly welcome. You have to seem harmless even though you are secretly deadly."
