Final answer:
The claim that Miller Light Beer, Maxwell House Coffee, Jell-O brand gelatin, Kraft mayonnaise, and Marlboro Cigarettes were all products of Philip Morris is false. Marlboro was a Philip Morris product, but the other brands were produced by different companies at the time specified.
Step-by-step explanation:
The statement that Miller Light Beer, Maxwell House Coffee, Jell-O brand gelatin, Kraft mayonnaise, and Marlboro Cigarettes were all at one time products of the Philip Morris Company is false.
While it is true that Marlboro Cigarettes were a product of Philip Morris, the other brands were produced by different companies. For instance, Miller Light Beer is associated with the Miller Brewing Company, Maxwell House Coffee with General Foods, Jell-O with Kraft Heinz, and Kraft mayonnaise is a product of Kraft Heinz. It is important to recognize that over time, large corporations may acquire a variety of brands, so market compositions can change, but at any given point, certain brands are usually associated with particular companies.
