Hello. You have presented the excerpt to which this question refers, which makes it impossible to elaborate an answer with accuracy. However, I will try to help you in the best possible way.
To paraphrase the excerpt, it is necessary, first, that the excerpt be read. After reading it, you must rewrite it keeping the message he wants to pass on to the reader, but using other words. In short, a paraphrase occurs when a text is rewritten while retaining the original meaning, but using different words.
To explain how the author constructs the argument, you must observe the supporting sentences that he presents. So you can see the structure of the text and present how the author constructed his opinions.
The correct answer is "A".
It is previously known by the reader that all the villagers in town are gathering together for the traditional lottery which is celebrated every June 27. However, due to the small population in the town (only 300 people), there is an expectation for Tessie's arrival at the event, due to the fact that every resident is expected to participate. This is known when the person responsible for leading the event asks if there is anyone missing and she gets the immediate response that an individual named Dunbar is not there.
The sentence that contains a boldface infinitive is D. Lisa wants TO GO.
It is easy to spot an infinitive - it is usually a combination of the word TO plus a verb.
A and C are incorrect because those are not infinitives, but rather prepositional phrases. B is incorrect because it is an infinitival phrase, rather than a single infinitive.
