Question

-the construction of the aswan dam was completed in 1970, and its primary purpose is flood control, irrigation, and the generation of hydroelectric power.
-the hoover dam is located in the united states, on the colorado river, near the border between the states of nevada and arizona.
-construction on the hoover dam was completed in 1935. the primary purposes of the hoover dam are flood control, water storage, and hydroelectric power generation.
-the construction of aswan dam led to the creation of lake nasser and the construction of the hoover dam led to the creation of lake mead, both of which serve as regional water storage facilities.
the student wants to compare the purposes of the two dams. which choice most effectively uses relevant information from the notes to accomplish this goal?
a while they both serve to control flooding, the aswan dam was built to aid irrigation efforts while the hoover dam was built to create a water storage area.
b both the aswan and the hoover dams were designed to control flooding and generate hydroelectric power.
c both dams resulted in the creation of lakes that serve as water storage facilities.
d although the aswan dam is located in egypt and the hoover dam is located in the united states, they both serve vital energy and

Explanation:

To compare the purposes of the two dams, we analyze each option:

• Option A: The Aswan Dam's primary purpose includes flood control, irrigation, and hydroelectric power, while the Hoover Dam's purposes are flood control, water storage, and hydroelectric power. This option incorrectly states the Aswan Dam was built to aid irrigation and the Hoover to create a water storage area (both have multiple purposes, and this misrepresents their main focuses).
• Option B: The notes state both dams were designed for flood control (Aswan: flood control; Hoover: flood control) and to generate hydroelectric power (Aswan: hydroelectric power; Hoover: hydroelectric power). This matches the information about their purposes.
• Option C: This option focuses on the result (creation of lakes as water storage facilities) rather than the purpose of the dams, so it does not address the goal of comparing purposes.
• Option D: This option compares their locations and a general "serve vital energy" (too vague) instead of their specific purposes, so it is not relevant to the goal.

Answer:

B. Both the Aswan and the Hoover Dams were designed to control flooding and generate hydroelectric power.
