Question

1. ** which choice best describes the function of the underlined portion in the text as a whole? 1 point

2 ** antarctica is a tough place to work, for obvious reasons—it’s bitterly cold, remote, and wild. however, it’s one of the best places in the world to hunt for meteorites. that’s partly because antarctica is a desert and its dry climate limits the degree of weathering the meteorites experience. on top of dry conditions, the landscape is ideal for meteorite hunting: the black space rocks stand out clearly against snowy fields. even when meteorites sink into the ice, the glaciers’ churning motion against the rock below helps re - expose the meteorites near the surface of the continent’s blue ice fields.
(a) to describe the difficulties faced by meteorite hunters in the antarctic
(b) to explain how antarctica’s blue ice fields affect meteorites’ composition
(c) to compare the surface conditions of antarctica to the conditions in outer space
(d) to emphasize a feature of the antarctic landscape that allows meteorites to become exposed

Explanation:

• Option A: The underlined part doesn't talk about difficulties for hunters, but about how meteorites are exposed. Eliminate A.
• Option B: It doesn't discuss meteorites' composition, but their exposure. Eliminate B.
• Option C: There's no comparison to outer space conditions. Eliminate C.
• Option D: The underlined text explains how glaciers' motion (a landscape feature) helps re - expose meteorites, which matches this option.

Answer:

D. To emphasize a feature of the Antarctic landscape that allows meteorites to become exposed
