MartyMurray. Need your help between C and E. Why is C a better option? In C, if the employees do not travel by train and instead WFH, wouldn't the carbon emission go down? Why is it the correct answer? Doesn't seem to threaten the conclusion
Agree. E is a better weakener. Some = 1 to all. On the other hand, We are not sure if light-rail system is used frequently by 2/3 of employees or light-rail system is energy efficient.
Indeed this question is busted.

I wouldn't say (E) is better. I would have marked (C) here. Focus on the intent of the author.
He says " the company estimates that its carbon emissions will be
significantly reduced because workers will not have to drive back and forth between their homes and Flimco headquarters."
So the reason given is savings in energy spent during commute.
(C)
A majority of Flimco's employees travel to and from work on a light-rail system that runs every 15 minutes, regardless of ridership.
Says majority of people commute by this rail which will continue with the same frequency, even if it is empty. So it doesn't matter whether employees are commuting or not, the same energy is being used. So not commuting is not saving energy.
It is a weakener of the plan.
(E)
Some of Flimco's workers live in homes that are not energy efficient, and would expend more nonrenewable energy maintaining the climate in their homes telecommuting than they would if they left their residences to work elsewhere.
I don't know what "some" is. It could be very few or many. Hence I don't know if this option has a "significant" impact.
Answer (C)
