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

Scenario 3-1
In the early and mid-1800s, soaps were made from animal fats. The perishable quality of the soap, however, allowed manufacturers to sell a product with only regional appeal. This changed when soap makers began to use vegetable fats and perfume in the soap-making process.
According to Procter & Gamble legend, 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." (Stephen Fox, The Mirror Makers, [New York: Random House, 1984], 24.)
-(Scenario 3-1) One effect of the passage of the Pure Food and Drug Act of 1906 was that

A) the manufacturers of Ivory soap had to list its ingredients on the label.
B) advertising claims for Ivory soap became strictly regulated.
C) Ivory soap had to become 100 percent pure.
D) branded products had to trademark their brand names.
