The correct answer is D. Reading on a daily basis is very important for building your vocabulary

Explanation:

Vocabulary building refers to the process of extending the amount and complexity of words that you later use in conversations, texts or speeches, this allows you to understand better texts and communicate your ideas effectively. One of the most important ways to learn and acquire new words is reading on a daily basis as reading almost any kind of text usually implies encountering new words and by doing this you will be able to learn the meaning of the words from its context or looking for it in a dictionary or other sources and by knowing the meaning, later you can integrate them in your speech or writing (building vocabulary). Thus,  reading on a daily basis is very important for building your vocabulary as it is an important source of new words that you can integrate into your vocabulary and use when speaking or writing.

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.
