answer bank
ineffective
effectively
effectiveness

Explanation:

1. The first blank needs a noun to follow the possessive "their" and fit the phrase "reduce their ____", so "effectiveness" (the noun form of "effective") is correct.
2. The second blank needs an adverb to modify the verb "listen", so "effectively" (the adverb form of "effective") is used to describe how students cannot listen well.
3. The third blank needs an adjective to describe people's ability at multitasking, contrasting the idea of effective multitasking, so "ineffective" (the negative adjective form of "effective") is appropriate.

Answer:

1. effectiveness
2. effectively
3. ineffective
