Explanation:

1. In a toaster, the timer/darkness setting controls how long the heating element is on, thus controlling the level of toasting. The heating element generates heat, the bread slot holds the bread, and the electrical cord provides power. So the control mechanism is the timer/darkness setting.
2. Information Technology, Communication, and Biotechnology are common major categories of technological systems. Agriculture is a broad - based industry but not typically considered one of the main technological system categories in the same context as the others.
3. The primary function of a transportation system is to move people or goods from one place to another. Storing information is not its function.

Answer:

1. The timer/darkness setting
2. Agriculture
3. To move people or goods
