Can someone help me with the question in the image? if it is correct i will mark as brainliest

I would think the correct answer would be B and D.  

Explanation:

The information the institutions gathered doesn't tell whether the temperature increased or decreased so it couldn't be A. And the data that is gathered by each institute is similar to one another, so it couldn't be C. Therefore, you're left with B and D.

I hope this helps!

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.

i think   the answer is c hope i'm right
