OFFICIAL EXPLANATION
The correct answers are $\(\mathbf{A}\)$ and E .
Answer Blank (i): Once you figure out all the negatives in the sentence, you'll see that you need two words that balance each other. Choice A, "improbable," means "unlikely to happen." Choice B, "unusual," meaning "out of the ordinary, odd" doesn't strike the right significance in describing putting a human on the moon. Choice C is incorrect because "fortuitous" means "happening by chance, unplanned," the opposite of requirements for the space program.
Answer Blank (ii): Choice E, "feasible," meaning "possible, viable" balances "improbable" when you add the "not" from the sentence in front of "feasible." Choice D, "serviceable," means "usable, capable of lasting for a long time." The latter definition makes it a synonym for choice F, "durable," but you're not looking for synonyms, and those words don't make sense in the context.
