In each of the following questions, choose the option that best completes the gap(s). As trained teachers, Joke teaches _______ better than Jumoke.

The sentence "As trained teachers, Joke teaches _______ better than Jumoke" contains the comparative adverb "better." The blank requires a word that can modify and intensify this comparative form.

The correct answer is far. "Far" is one of the adverbs that can intensify comparatives, producing "far better," which means "much better" or "considerably better." The sentence means that Joke's teaching ability significantly exceeds Jumoke's.

The other options cannot correctly modify a comparative:

• "Too" means excessively and modifies adjectives and adverbs in their base form ("too loud," "too fast"), not comparatives.
• "Very" also modifies base adjectives and adverbs ("very good," "very well"), not comparative forms. "Very better" is not standard English.
• "More" would create a double comparative ("more better"), which is grammatically incorrect since "better" is already the comparative form of "good/well."

Other adverbs that can modify comparatives include much, even, still, a lot, and significantly.
