For this question, select the option that best explains the information conveyed in the sentence.
The students felt the lecture was a load of crap.
Answer Details
The expression "a load of crap" is an informal idiom meaning something is nonsensical, worthless, or of extremely poor quality. When the students felt the lecture was "a load of crap," they judged its content to be foolish and without value.
The closest option is that the students thought the lecture was stupid - meaning they found its content to be of no intellectual worth.
Believing the lecture was "too long" addresses duration, not quality. Refusing to listen or not attending the lecture describes actions the students might take, but the idiom specifically expresses their opinion about the quality of the lecture's content, not what they did in response.
