Question

Read the sentences from paragraph 5 of the selection.
The group that leaves Bracken Bat Cave each night is so large that it can be tracked by radar. Radar is commonly used to predict weather by following moving objects, such as raindrops, in the sky.
Which is the best paraphrase of these sentences?
A
Bats regularly leave Bracken Cave during the evening and can be tracked by radar. Radar is often used for giving weather updates, such as upcoming rainstorms.
B
The bats that leave Bracken Cave at night are often mistaken for raindrops by weather radar. Radar is an important tool that is used to follow storms that move in surrounding areas.
C
So many bats exit Bracken Cave each night that the group can be tracked with the same radar used to track weather. Radar tracks objects, like drops of rain, as they move through the air.
D
A large group of bats journeys from Bracken Cave. Weather radar is used to look out for approaching rainfall, but it can sometimes be used for other research purposes.

Answer 1

C

Choice C best preserves the original meaning and details: it keeps "each night," notes the bats are numerous enough to be tracked by weather radar, and restates that radar follows moving objects like raindrops.
