Direction: Arrange these parts so as to form a complete meaningful…

Concept: In sentence rearrangement, a fragment set must attach to a fixed anchor clause, and any pair joined by a coordinating conjunction (and/or/but) must be grammatically parallel and share the same governing word (verb or preposition).

Application: Here the anchor is "Life appears to me". "Too short to be spent" is the verb-complement that directly completes this anchor, so it must come first. "In nursing animosity" and "registering wrongs" are two gerund phrases joined by "or" and both governed by the preposition "in" — for "or" to correctly link them as parallel alternatives, "in nursing animosity" must appear first and "or registering wrongs" immediately after it.

Cross-check: Checking the other arrangements confirms this:

• "too short to be spent" followed by "or registering wrongs" then "in nursing animosity" separates the two gerund phrases that must sit together under "in", so "or" ends up joining unrelated elements.

• "in nursing animosity" placed right after the anchor clause, before "too short to be spent", breaks the anchor's grammatical completion — the anchor needs its duration clause first.

• "or registering wrongs" opening the sequence right after the anchor has no preceding item for "or" to connect to, so the conjunction has nothing to join.

Hence, the correct combination is P-R-Q.
