The incorrect answers will either misinterpret the episode as a case of bad luck ("mischance"), poor circumstances ("adversity"), or a failure to address the topic at hand ("temerity"). "Spontaneity" comes close by referring to the seeming randomness of the event, but is not as good of a fit as "serendipity."

Since the girl is afraid of the dark, it would be very important to bring a flashlight on Halloween. This importance is stressed by the sentence's use of "absolute." The only answer choice that conveys this sense of importance is "necessity," making it the correct answer.

The sentence describes a speech given following someone’s death that is moving; this indicates that the correct answer is eulogy. A eulogy is a tribute or speech given for someone who has died.

The word “antithesis” means “the direct opposite.” To help memorize the word, think of it in terms of being the “anti-thesis”—the opposite of the “thesis” proposed by another’s character. Although this will help you memorize it, do remember that the word “antithesis” can be applied to anything that directly opposes another thing. As a vocabulary note, “antithetical” is the adjective form meaning “being directly opposed.”

The key phrase to note is “able to heal a countless number of ailments.” A “panacea” is something that is believed to be able to cure every sort of ailment.
