Question

how can the senate limit the power of the house?
by not sending bills to the house
by not approving the houses bills
by being the upper chamber
by having six-year terms

Explanation:

In the U.S. legislative system, both the House of Representatives and the Senate are involved in the law - making process. A bill must pass both chambers to become law. If the Senate does not approve a bill that originated in the House (or vice - versa), it cannot move forward. The Senate, as one half of the bicameral legislature, has the power to reject House - passed bills, thus limiting the House's power.

• Option A is incorrect because the Senate does not have the role of "sending bills to the House" in the traditional sense. Bills can originate in either chamber.
• Option C, while the Senate is the upper chamber, this is more of a structural description rather than a direct power - limiting mechanism.
• Option D, the length of Senate terms (six years) is related to the stability and different constituency representation compared to the House (two - year terms), but it is not a direct way of limiting the House's power.

Answer:

B. by not approving the House's bills
