GMAT Critical Reasoning (CR) | Re: CR Challenge Question: Bumblebees OG 2016

I agree with the E choice explanation. But still I have the same question as HiLine.
The correct answer E uses "can", which simply disturbs/challenges my CR skills and rules.If the option was like this :Soil disturbances results in fewer blooms, and hence lower seed production. . It is a spot on. Yeah, now we know the correct answer we can build on..and on...

Most of the time I eliminate if the answer choices hascan/will.
Experts can you touch on situations for weaken type CR where
