What is an example of an allusion.' a. The wind whipped like a rippling storm
b. She was as cold as ice
c. The mist rolled over the trees in the mountains

c. The mist rolled over the trees in the mountains.

Explanation:

An allusion is an expression that refers to another person or thing without making a direct reference to it. In other words, allusion is talking about something without directly referring to it.

Among the given sentences, sentence c is an allusion. It alludes to or refers to the mist as "rolling over" the trees. While the other two sentences are similes with their use of "as" and "like" in making the comparisons.

Thus, the correct answer is option c.

the speech this question is referring to is president kennedy's special message to the congress on urgent national needs, may 25, 1961

kennedy responds in a very direct and concrete way to those thinking that communism is a positive system:

"yet their aggression is more often concealed than open. they have fired no missiles; and their troops are seldom seen. they send arms, agitators, aid, technicians and propaganda to every troubled area. but where fighting is required, it is usually done by others--by guerrillas striking at night, by assassins striking alone--assassins who have taken the lives of four thousand civil officers in the last twelve months in vietnam alone--by subversives and saboteurs and insurrectionists, who in some cases control whole areas inside of independent nations." (kennedy)

president kennedy presents communism as cowardly, as a hidden and treacherous weapon that strikes from the shadows like thieves, he represents the system as not even being capable of showing and open and overt attack or confrontation. to finish up the response, he expresses that the system attacks even a country's idependence and freedom.
