b. eliminating of global warming became overwhelming.
c. scientists mistakenly thought pollution reflected sunlight and heat rather than absorbed it.
d. congress required scientists to assign a cause to global climate change.
please select the best answer from the choices provided
a
b
c
d

Explanation:

To determine why pollution once blamed for global cooling is now linked to global warming, we analyze each option:

• Option A: If pollution reflects sunlight (instead of absorbing it), it would have a cooling effect. But we need to explain the shift to warming, so this doesn't fit.
• Option B: "Evidence of global warming became overwhelming" doesn't directly explain the shift in the role of pollution (from cooling - causing to warming - causing). It's about the prevalence of warming evidence, not the pollution's role change.
• Option C: If scientists mistakenly thought pollution reflected sunlight (cooling) but it actually absorbs heat (warming), this explains the shift. Initially, they thought pollution caused cooling (by reflecting), but later realized it causes warming (by absorbing).
• Option D: Congress requiring scientists to assign a cause is not a scientific explanation for the shift in pollution's role. It's a policy - related action, not a scientific reasoning for the change in understanding.

Answer:

C. Scientists mistakenly thought pollution reflected sunlight and heat rather than absorbed it.
