A. as residents of pine grove st. condominiums, i am certain that you will agree with me when i state that having curfews on week nights will to reduce noise pollution for our community. is this ethos, pathos or logos

The answer is: logos.

Logos is an invocation or pretense to logics. It provides evidence to support a claim, although it might be erroneous, false or confusing. In the example sentence, the speaker's plea about curfews on week nights is supported by the sensible reason that it will help reduce noise pollution.

The rest of the choices are incorrect because ethos is an appeal to the credibility of the speaker, and pathos is an appeal to the audience's emotions.

merry christmas to you, too. may god be with you all in doing your work and just living a great life in general! < 3
