Question

which statement best summarizes the information in this selection?
a the california sea otter is a fascinating creature that has been known to use tools to get to its food supply. this playful predator lives in chilly water, where it must make up for its lack of blubber by consuming large amounts of food.
b the california sea otter is a predator whose presence is vital to its coastal habitat. the once - endangered animal is now protected, but its numbers remain low. recent research suggests that the failure of otter populations to increase is directly related to their consumption of contaminated prey.
c california sea otters were mercilessly hunted for fur and nearly became extinct by the turn of the 20th century. since 1911, they have been protected by a law that banned hunting otters for fur. however, this protection has failed to significantly increase the otter population.
d california otters tend to restrict their diets. a researcher proposes that these otters tend to organize themselves in groups according to dietary preferences. these preferences cam prove dangerous to otter populations if the food sources become contaminated.

Explanation:

To summarize the information, we need to consider all key - aspects of the California sea otter such as its ecological importance, conservation status, and threats. Option A only focuses on the otter's behavior and habitat related to food. Option C only emphasizes the hunting history and protection law. Option D only talks about diet and potential risks. Option B covers the otter's importance to the habitat, its conservation status (once - endangered, now protected but numbers low), and a recent research finding about the threat to its population (contaminated prey).

Answer:

B. The California sea otter is a predator whose presence is vital to its coastal habitat. The once - endangered animal is now protected, but its numbers remain low. Recent research suggests that the failure of otter populations to increase is directly related to their consumption of contaminated prey.
