Advertisement: The Country Classic is the only kind of car in its class that offers an antilock braking system that includes TrackAid. An antilock braking system keeps your wheels from locking up during hard braking, and TrackAid keeps your rear wheels from spinning on slippery surfaces. So if you are a safety-conscious person in the market for a car in this class, the Country Classic is the only car for you.

The advertisement says that the Country Classic is the preferable car in its class for safety-conscious consumers. This is because it has an antilock braking system that includes TrackAid. These safety features help when hard braking and driving on slippery sufaces, respectively.

Notable Assumptions
The advertisement says that having TrackAid in addition to an antilock braking system makes Country Classic safer than other cars in its class—by saying this, it implies that other cars lack alternatives to TrackAid that equally increase safety.

A
All of the cars that are in the same class as the Country Classic offer some kind of antilock braking system.
This does not affect the advertisement. The advertisement does not claim that others cars lack an antilock braking system—it claims that other cars lack an antilock braking system that includes TrackAid.
B
Most kinds of cars that are in the same class as the Country Classic are manufactured by the same company that manufactures the Country Classic.
This does not affect the advertisement. The same company can manufacture cars with different features and systems.
C
Without an antilock braking system, the wheels of the Country Classic and other cars in its class are more likely to lock up during hard braking than they are to spin on slippery surfaces.
This does not affect the advertisement. It discusses cars that lack an antilock braking system, whereas we know that the Country Classic does have this feature, which is part of what purportedly makes it safer than other cars.
D
Other cars in the same class as the Country Classic offer an antilock braking system that uses a method other than TrackAid to prevent rear wheels from spinning on slippery surfaces.
This weakens the advertisement. It attacks its assumption that TrackAid is the only way to prevent rear wheels from spinning on slippery surfaces: if other cars have an equally safe alternative method of prevention, they could be just as safe as the Country Classic.
E
The Country Classic is more expensive than any other car in its class.
This does not affect the advertisement, which discusses safety, not price.
