Fill in the blank with the comparative degree of the adverb: Could you write _________________________________? 

Adverbs in a sentence modify a verb, an adjective, and sometimes another adverb. The terms "early," "slowly," "home," and "hard" in "arrived early," "runs slowly," "stayed home," and "worked hard" are all adverbs.

Like adjectives, certain adverbs have three degrees of comparison.

If the adverb is one syllable, we make the comparative by adding er to the positive, and the superlative by adding est, as in 'fast-faster-fastest.'

Adverbs that end in ly form the comparative by adding more and the superlative by adding most; for example,'swiftly-more speedily-most swiftly'.

Option B is accurate in this case since more clearly is the comparative form of plainly. As a result, the remaining alternatives are null and void.
