Question

the following is a draft of a student essay. it may contain errors. in the zone (1) before winter sets in, some animals fly south, others prepare to hibernate, and some stay active in the snow. (2) however, small rodents will adapt what is known as the subnivean zone into their winter home to survive and thrive. (3) existing grass close to the ground supports the first snowfall, and, thanks to sublimation, creates the perfect winter habitat for these small burrowing animals. (4) they will have a sturdy frozen roof formed over their heads. (5) the rooms below will maintain a constant \warm\ temperature of 32 degrees fahrenheit. 3 which information could be added to this introductory paragraph to further develop the topic? a. a description of the rodents that live in the subnivean zone and what they will eat during winter b. a statement explaining why the subnivean zone is important c. a description of the animals mentioned in the first sentence to highlight the differences between animals that do and do not live in the subnivean zone d. an explanation that the subnivean zone is an insulated tunnel under the snow that protects animals from the cold and other predators outside

Explanation:

The paragraph focuses on the subnivean zone as a winter - habitat for small rodents. Adding a description of the rodents in this zone and their winter diet would further develop the topic related to the subnivean zone. Option B is too general about the importance of the zone without specific details related to the rodents. Option C is about animals in the first - sentence in general, not specifically about the subnivean zone. Option D is more about the structure of the subnivean zone rather than the animals in it.

Answer:

A. a description of the rodents that live in the subnivean zone and what they will eat during winter
