"The committee system is the heart of the legislative process. The committee does what the Senate and the House of Representatives could not do as well by functioning as a whole. The committee can and should do the fact-finding groundwork. The formation of committees breaks down the membership into numerous small groups. Opportunity is thus afforded the Senate and the House for closer study of a bill than would be possible in debate on the floor. In this preliminary screening, the committee will hear from the legislator who introduced the bill. It will hear, too, from other legislators who either favor or oppose the bill." According to the passage, what is the PRIMARY advantage to using the committee system in the legislative process? A) Committees are necessary to make the legislative process more efficient. B) Committees are necessary to prevent the governor from vetoing the legislation. C) Committees are mostly a tradition and actually slow down the legislative process. D) Committees make the legislative process more accessible to the citizens of the state.
