Question 3 • *26-27 CFISD TX-Chemistry A CR

After World War II, people began living in suburban areas. How might the movement of people from cities to suburbs be related to the development of pesticides by chemists?

Answer

Pesticides were needed in urban areas for pests that moved into abandoned apartments, such as ants, bees, and other insects.

Pesticides were used to help convert farmland into lawns and to rid new homes and neighborhoods of insects.

Pesticides were needed to kill foreign species of insects that were carried into the country on the clothing and military equipment of troops returning from war.

Pesticides were developed in suburban factories, so the sale of pesticides was heavily promoted to bring more money to the factories.

Explanation

As people moved into suburbs, new homes and neighborhoods were often built on land that had been farmland or undeveloped areas. Pesticides helped control insects around the homes and yards, while lawns replaced some former farmland. So choice B best connects suburban growth with pesticide use.
