Option A: Out of context, we are not concerned with temperature next year
*Eliminated*
Option B: para mentiones temperature in Canada was as dangerously high, no where comparison is mentioned
*Eliminated*
Option C: the word “certain” is a red flag here, the paragraph says heat related death toll increased, not air conditioning related
( a trap option choice i feel)
*Eliminated*
Option D: Great Depression is just real world assumption which is not mentioned in the passage
*Eliminated*
Option E: assumption sounds correct and possible. Note that the first line of the paragraph says “serious environmental and *economic problem*”
More crop damage> Less availability> Price Increase —> economical effect of the heatwave. Hence option E stands correct
hope it helps
