Are the quarter-pound footlong hot dogs made entirely of beef?

The assertion that quarter-pound footlong hot dogs are made entirely of beef is false. These hot dogs can be a blend of meats, which may include beef but could also incorporate other types of meat or fillers, depending on the specific product and manufacturer's recipe. Therefore, they are not guaranteed to be 100% beef. This distinction is important as it reflects nutritional content and dietary restrictions that may be relevant to consumers.

The other options suggest different scenarios, such as some instances where the product might be all beef or variation by location. However, the consistency in ingredients would not align with the common practice in food manufacturing for these items. Rather, being aware that the product is not exclusively beef clarifies the correct answer.
