Select the sentence that uses the correct comparative form for a two-syllable adjective.

Answer and explanation

Correct answer: C. This newly constructed hydroelectric dam is safer than the decommissioned one.

  1. Step 1: The one-syllable adjective 'safe' forms its comparative by adding -r: 'safer'. Step 2. Using 'more safe' is non-standard, and 'more safer' is a double comparative error. Answer: This newly constructed hydroelectric dam is safer than the decommissioned one. Why not the others: 'More safer' is a double comparative; 'safe than' omits the comparative marker.
