Ireturned home late after a tough day at work, but my roommate forced me to do the onerous task of cleaning the kitchen. based on the context, onerous likely means relaxing burdensome enviable

B. Burdensome

Explanation:

Hi. According to the passage, the answer would be option B. This is because onerous is a task or responsibility that involves an amount of effort and difficulty that is oppressively burdensome.

In this case, the pararaph has a heavy tone since the writer is saying he got home late after a hard day and, on top of that, he had to clean the kitchen. Based on this paragraph, burdensome would be the word that fits better.

the sentence that best describes the tone of the passage from the radio broadcast compared to the passage from the book is b. the radio broadcast has a more surprised tone.

consider the text evidence: in the passage from the book, the description is more matter-of-fact. it is simply describing the things resembling little grey snakes, but there is no urgency in the description. on the other hand, in the passage from the radio broadcast, there is definetely urgency (you can tell from the expression used, "good heavens", which clearly indicates surprise.)
