A recent study by a leading automotive expert claims that the new Falcon electric vehicle is highly efficient, has a longer range than any competing model, and is priced lower than similar vehicles on the market. Based on this, the manufacturer’s report suggests that the Falcon will quickly become a popular choice among consumers looking for an affordable electric vehicle.

Which of the following, if true, would LEAST weaken the argument above? (A) Many dealerships already offer several affordable electric vehicle options and may not be interested in adding another. (B) Other manufacturers are planning to release electric vehicles that are both cheaper and have a longer range in the near future. (C) The Falcon electric vehicle is compatible with charging stations designed for more expensive electric vehicles from other brands. (D) Most potential buyers of electric vehicles have already purchased one and may not be in the market for a new vehicle soon. (E) The automotive expert whose evaluation was included in the report has used criteria for efficiency that are not widely recognized by consumers.
