Complete the following sentence with the correct form of the adjective:
It was _____ car he had ever driven.

Question

Accepted Answer

Option 2, "the most comfortable," is the correct choice for completing the sentence "It was _____ car he had ever driven." Here's why:

1. **Explanation for Option 2:**
   - The phrase "the most comfortable" is the superlative form of the adjective "comfortable." Superlatives are used to describe the highest degree of a quality among three or more items. In this sentence, the speaker is comparing the comfort level of this car to all other cars he has driven. Therefore, using the superlative form "the most comfortable" accurately conveys that this car is the most comfortable of all the cars he has experienced.

2. **Why the other options are incorrect:**
   - **Option 1: "the more comfortable"**
     - This option uses the comparative form "more comfortable," which is used to compare two items. However, the sentence implies a comparison among multiple cars, not just two. Therefore, the comparative form is inappropriate in this context.
   
   - **Option 3: "the comfortable"**
     - This option does not use a comparative or superlative form. It simply uses the adjective "comfortable" without indicating any comparison. The sentence requires a superlative form to express that this car is the most comfortable among all he has driven.
   
   - **Option 4: "the comfortablest"**
     - This option attempts to form a superlative by adding "-est" to "comfortable." However, "comfortable" is a multi-syllable adjective, and the correct superlative form is "the most comfortable," not "the comfortablest." Therefore, this option is grammatically incorrect.

In conclusion, Option 2, "the most comfortable," is the correct choice because it appropriately uses the superlative form to indicate that this car surpasses all others in terms of comfort.
