Which choice completes the text so that it conforms to the conventions of Standard English?

A

saved

B

saves

C

would have saved

D

will save

Correct Answer: C

Choice C is the best answer. This question tests verb tense in past unreal conditionals.

  1. Context clues: "If... had invested" (past perfect) signals a past unreal condition.
  2. Meaning: Past unreal conditionals use would have + past participle in the result clause.
  3. Verify: "If... had invested... would have saved" follows the past unreal conditional pattern.

💡 Strategy: Past unreal conditionals: if + had + past participle, would have + past participle.

Choice A is incorrect because simple past doesn't match the conditional structure. Choice B is incorrect because present tense is wrong. Choice D is incorrect because future tense doesn't match past unreal conditions.
