The first option, "[she] just couldn't stand another minute of the incessant howling", seems to be the best one to finish the paragraph. First of all, the paragraph has very specific and powerful vocabulary like "bopping his head" and "burst". So a concluding sentence should also have strong vocabulary. In this case "howling" is a very descriptive and powerful verb. Moreover, in the paragraph, the narrator mentions that "[the] lead singer sounded as (...) a dog lost in the woods". Using the word "howling", which is something done by dogs, in the concluding sentence would be consistant with the comparison between the singer and a lost dog.
The answer choice is true. last i check it does.
Completed would be the verb because it is an action
