From the words or group of words lettered A to D, choose the word or group of words that best completes each of the following sentences.

The spectators had to endure the endure the heat _____ 

Answer Details

The sentence is asking how the spectators endured the heat, which means it requires an adverbial phrase indicating the manner in which they endured it. The correct answer is "as best they could" because it conveys that the spectators did their best to endure the heat, which is what the sentence is trying to express. The other options, such as "as they could" or "as they could best," do not convey the same level of effort or determination as "as best they could."
