LSAT 109 | Section 2 | Reading Comprehension: Q17

RC Question 17 Explanation

DISCUSSION: The last paragraph attacks the second part of the argument from the first paragraph (more plants means less CO2).

Plant growth likely won’t slow CO2 growth. Higher temperatures will release CO2 from the tundra.

___________

1. CORRECT. The hypothesis was that increased plant growth would slow overall CO2 growth. Unfortunately, the last paragraph tells us that CO2 reduction from plant growth will likely be offset by CO2 released from the tundra. 
2. There are no solutions given, just a grim prediction: melting tundra will release CO2.
3. There’s no explanation given. Instead, the third paragraph attacks the first paragraph.
4. The second paragraph talked about agriculture and wildfires. The third paragraph doesn’t address that; it talks about CO2 from the tundra. 
5. This is close. But doubt is cast on the information from the first paragraph. The second paragraph is about agriculture, and the third paragraph leaves that alone.
