Question: 301

5. According to the passage, manatees prefer the shallow coastal waters of Florida because of which of the following?

I. Availability of vegetation

II. Favorable water temperatures

III. Safety

  • A. I only
  • B. I and II only
  • C. II only
  • D. I, II, and III

Correct Answer: B

Explanation:

B is correct. As stated in the passage, “sirenians eat only seagrasses and other aquatic vegetation.” These grasses grow best in shallow waters where sunlight can penetrate. Additionally, “sirenians have an extremely low metabolism and zero tolerance for cold water”; therefore, they need the warmer temperatures of Florida’s coastal waters. There is no mention of safety in the passage, and in fact, these very waters are also attractive to people in speedy powerboats, who pose the biggest danger to slow–moving manatees.
