The second experiment was ____ than the first because the sample was larger.

Answer and explanation

Correct answer: A. far more reliable

  1. Step 1: The sentence compares two things, so a comparative form is needed. Step 2. 'Far more reliable' is a correct comparative with an intensifier. Answer: far more reliable. Why not the others: 'much reliable' lacks the comparative 'more'; 'more reliably' is an adverb; 'most reliable' is a superlative for three or more items.
