Question 3

GreenGrid installs shared solar arrays on apartment-building rooftops and sells subscriptions to residents, promising lower electricity bills. In one pilot building, subscribers' average monthly electricity bills fell 18 percent in the months after the array went live. On the strength of this result, GreenGrid concludes that its solar subscriptions reliably reduce residents' electricity costs.

Which of the following, if true, most weakens GreenGrid's conclusion?

Accepted Answer

The array in the pilot building began generating power just as the building entered its mildest season, when residents' electricity use naturally reaches its annual low.

Answer

GreenGrid intends to expand the program to twelve additional buildings within the next year.

Answer

A rival provider offers comparable rooftop solar subscriptions for a slightly higher monthly fee.

Answer

During installation, the array's construction blocked part of the building's parking lot for several weeks.

Answer

Most subscribers said they signed up mainly to reduce their carbon footprint rather than to save money.
