We are warned that climate changes are destined to reduce food production. More hopeful experts claim that food production will change very little because there is little reason to expect altered rain distribution even with climatic changes. For most crops, annual fluctuation and agricultural technology mask yield changes due to climate.

The more hopeful claims are based on which of the following assumptions?

A) Technology is so influential that regardless of climate, improved yields are unlikely.

B) Climate changes cannot be predicted with accuracy.

C) Temperature trends are more predictable than rainfall trends.

D) Cooling trends threaten food production more than warming trends.

E) Climate changes would be more damaging if rainfall patterns are coupled with them.

E... Looks like the answer as the experts feel that there will be not much rain pattern change with climate change.
Though I am confused. Answer will be appreciated

More hopeful experts claim that food production will change very little because there is little reason to expect altered rain distribution even with climatic changes. For most crops, annual fluctuation and agricultural technology mask yield changes due to climate.

The more hopeful claims are based on which of the following assumptions?

Expert: No change in rain, so less impact. Assumption: Less rain is bad/ more damage

A) Technology is so influential that regardless of climate, improved yields are unlikely. -- Misinformation about information given above (technology helps mitigate affects and more technology would help produce, not reduce). This is a trap answer

B) Climate changes cannot be predicted with accuracy. -- This is true, but out of scope for this question

C) Temperature trends are more predictable than rainfall trends. -- Irrelevant to the question (nothing stated about the parallelism in predictability between rain and temperature)

D) Cooling trends threaten food production more than warming trends. -- This could be true as well, but out of scope and not what the question wants

E) Climate changes would be more damaging if rainfall patterns are coupled with them. -- This matches the assumption: Amount of rain to the output
