Hello. Although you have presented the text to which this question refers, you have not shown the answer options and you have not shown what was addressed by part A. However, I will try to help you in the best possible way.
"Why teens find the end of the world so applealing" is a text that shows how dystopic novels have the ability to communicate with teenagers in a very strong way, as it stimulates emotional responses in an unrealistic world to which they can relate. Part A and Part B are directly related to this text. In that case, to answer these questions, you should read the article to answer the Part A question and then look at what options in Part B can justify and show that your Part A answer is correct.
I would say the last answer could be wrong though.
Objects help to make an argument stronger, since they are real.
I don't see the specific choices, but maybe this will help...
The connotation (feeling of the word beyond the literal definition) here is negative. It is something silly or absurd/unjustified.

Hope this helps
