Question

which is the best way to complete the text? polar bears have translucent fur that appears white in the ______ makes them well adapted to life in the arctic, where blending in with the snow helps them approach prey undetected. sunlight; since this sunlight; this sunlight and this

Explanation:

To determine the correct option, we analyze the sentence structure and logic. The first part describes the polar bear's fur appearing white in sunlight, and the second part explains how this (the white appearance) helps them. The option "sunlight; this" correctly connects the two clauses: the first clause ends with "sunlight" (a semicolon is used to separate two independent clauses, and "this" refers back to the fur's appearance in sunlight, creating a logical flow. "sunlight; since this" would introduce a subordinate clause, but the second part is an independent clause, so "since" is unnecessary. "sunlight and this" would create a run - on or ill - structured sentence as the two parts have a cause - effect relationship better separated by a semicolon.

Answer:

sunlight; this
