Step 1: Understanding the context.
The passage discusses a scientific or philosophical explanation about the creation of species and natural selection. The correct set of prepositions must connect the ideas logically.
Step 2: Analyzing the options.
(A) At, of, in, to, through, as: The prepositions "at" and "to" are not appropriate in this context. "At" generally refers to specific locations or points, and "to" would not fit the second blank where we need a more suitable preposition like "for."
(B) For, of, in, though, as: "Though" is not appropriate here as we need a preposition that fits grammatically. It does not convey the right meaning.
(C) On, of, at, to, through, to: "At" and "to" are not ideal choices in these places. "To" in the first and second blanks doesn't create a smooth connection.
(D) On, of, in, to, through, as: "To" is not appropriate in this case because "to" should be used for directional relationships, and it is misplaced here.
(E) On, of, in, to, through, as: This set of prepositions fits the structure and meaning of the passage. "On" connects the first idea about the view; "of" fits with "explanation of"; "in" fits the context of the passage for the third blank, referring to the explanation's context; "to" works to connect "best of my judgment"; and "through" fits with the explanation of inheritance, and "as" concludes the passage with the idea illustrated.
Step 3: Conclusion.
The correct choice is (E) On, of, in, to, through, as as it logically completes the sentence while maintaining grammatical consistency.
