Answer

For the first blank, ‘has been orphaned and’ holds the context and makes the use of “rescued” perfect to the context as it means ‘to save (someone) from a dangerous or difficult situation’ and completes the sentence.

This eliminates all other options (C and D).

Also, for the second blank, ‘rehabilitate it’ in the sentence holds the context of the sentence and allows us to use “eventually” as it means ‘in the end, especially after a long delay, dispute, or series of problems’ and fits into the context completely as “event” will change the context of the sentence completely and that will make the sentence absurd.

This eliminates option B.
