Scenario 3-1In the Early and Mid-1800s, Soaps Were Made from Animal

Scenario 3-1In the early and mid-1800s, soaps were made from animal fats. The perishable quality of the soap, however, meant that manufacturers could only sell a product with regional appeal. This changed when soap makers began to use vegetable fats and perfume in the soap-making process. According to Procter & Gamble, one batch of this vegetable-based soap was left to mix too long. The result was a product that floated in water due to an excess amount of air. The company turned this into a selling point and, in 1882, launched one of the first soaps with the potential for national sales-Ivory soap-with the slogans "It floats" and "99-44/100 percent pure."
-(Scenario 3-1) One effect of the passage of the Pure Food and Drug Act of 1906 was that: 

A)  Ivory soap had to become hundred percent pure. 
B)  advertising claims for products like Ivory soap became strictly regulated. 
C)  the manufacturer of Ivory soap had to list its ingredients on the label. 
D)  branded products like Ivory had to trademark their brand names.
