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. 4 which sentence would be best to add after sentence 3 to better support the information? a. the snow will create a unique space just above the ground and make it possible for the rodents to live there undisturbed through the winter months b. they will turn the space between the snow and the ground into a cozy home where they can raise offspring even during the cold winter months. c. the rodents dig tunnels and make burrows in this habitat where the consumption of grasses will sustain them throughout the winter. d. snow falls on the ground but then sublimates, or turns into moist water vapor, which rises into the layer of snow directly above and hardens it

Explanation:

Sentence 3 mentions the winter habitat for small burrowing animals created by existing grass and sublimation. Option C best supports this by elaborating on the rodents' activities (digging tunnels and making burrows) and how they sustain themselves (by consuming grasses) in this habitat.

Answer:

C. The rodents dig tunnels and make burrows in this habitat where the consumption of grasses will sustain them throughout the winter.
