Respuesta :
i know this is late but I just took the quiz it's C: a negative effect of the problem
The data that Amaya has found regarding how pollution can cause serious respiratory-related illnesses can be framed in her presentation as (C) a negative effect of the problem.
The problem, in this case, refers to the air pollution, and thus the diseases caused by it can be presented to the audience as a negative impact of air pollution. It is most definitely not a positive effect.
