To determine which additional detail would be most effective to add to paragraph 3, it would be helpful to consider the overall context and focus of the paragraph.
If the paragraph discusses the impact of noise on the community, the best option would be:
"A few residents have complained that their health has been affected by being woken at night by loud noises."
This detail directly addresses the consequences of the noise issue and strengthens the argument for addressing the problem.
If the paragraph emphasizes differing opinions on the noise ordinance, then including the opinion of Lola Stetson or Gabrielle Tafoya could also be effective, but since the most impactful detail pertains to the effects on residents, the first option is likely the most effective addition.
