This is a super common issue that a lot of students face. In the closest answer choices, it can come down to a single word that invalidates an answer choice. Yes, the SAT does make things that difficult on purpose.
To get good at eliminating answer choices, you need to identify what part of the answer choice invalidates it, and why the passage doesn’t support that answer choice.
Remember that every correct answer choice is unambiguously correct and supported by the passage, and every incorrect answer choice is unambiguously incorrect because the passage fails to support it.

In this particular case, the two answer choices may seem similar, but they’re actually saying pretty different things. If you were to describe the general sentiment of each answer choice, they appear to be different:
“questions the literary value of science fiction” → “the author thinks science fiction is useless as a literary genre, likely especially compared to realistic fiction like Steinbeck or Austen”
“contrasts fictional notions with a scientific perspective” → “the author compares mythical science rumors with what’s realistic - eg ETs have a hold on the public imagination but are unlikely to exist at Area 51 for scientific reasons”
(I’m guessing at this based only on the answer choices you give me and not the passage… but I think I’m right)
If the author does NOT suggest that science fiction is a useless genre, then the first answer choice is wrong. If I were to guess based on your passage research, I would say this is likely to be the wrong answer choice, as it seems the passage is more about myths about ETs and UFOs than about science fiction.
I think you might also be confused about the use of “fiction” here. “Science fiction” is a specific literary genre, while “fictional” used in “fictional notions” means “imaginary” or “not confirmed by fact.”

Every time you miss a question, it’s important to go through this logic of being able to unambiguously eliminate all the incorrect answer choices. Otherwise you’ll never learn from your mistakes and move past your weaknesses.
