Answer:
Arranged.
Explanation:
Depending on the use of a word in a sentence, the meaning of a word may change. For instance, the word "contrived" means strained, pretended, or deliberately arranged, etc.
Now, looking at the use of that word in the given sentence, we can infer that the speaker is talking about ways to find a suitable solution for a return to earth. So, in that case, we cannot use the words "strained" or "pretended" in the sentence. Also, using "hindered" would also be wrong, as it possesses a negative effect rather than the main idea of trying to find a solution.
Thus, the correct answer to replace the word "contrived" while preserving the meaning in the sentence is "arranged".
