The correct answer to this open question is the following.
Yes, the growing number of interest groups support US Senator Byrd’s conclusion.
There is too much money involved in interest groups, and an increasing number of these groups have been appearing in the United States political scene. Senator Byrd was worried about this increased number and lack of control over these groups. Let's have in mind that these interest groups hire lobbyists to negotiate with legislators and offer support. But the US Congressmen had to be aware that it is the citizens that voted for them and put them in Congress as their representatives. So they serve the people, not the particular agendas of interest groups.
Media coverage gives voters an impression of the candidates.
Because much of media coverage comes in very brief news segments and even short "sound bites," it tends to provide an impression of the candidates, without necessarily providing in-depth presentation and analysis of their views. This varies, of course, depending on which "media" you have in mind with the question. Committed news organizations which employ highly skilled journalists will do deeper pieces on candidates and their views or policies -- see, for instance, articles in The New York Times or Washington Post or The Atlantic.
There are many new forms of media--such as social media websites and politically-aligned cable networks--where people can go to get biased perspectives and be told how to vote or not to vote. But the most respected media outets strive to present a full picture and cover all candidates. Still, because most voters will watch or read only portions of news media coverage, the best answer is that media tends to give voters an impression of candidates -- which sometimes is less complete than the full picture.
The correct answer is D.
Roosevelt Corollary is seen as an addition to the Monroe Doctrine in which the US stated it would not interfere with the politics of the European nations if they did not interfere in the Western Hemisphere. The Roosevelt Corollary was presented to the Congress after the Venezuelan crisis and it states that US will intervene and mediate the conflicts between European and the nations of Latin America and enforce any claims of the European nations if they are legitimate.
