A current-controlled, three-terminal semiconductor device used for the control and amplification of electronic circuitry is called transistor
A transistor is a semiconductor device that switches or amplifies electrical impulses. The transistor is one of the fundamental components of contemporary electronics. [1] It has at least three terminals for connecting to an electronic circuit and is made of semiconductor material. The current flowing through another pair of the transistor's terminals is controlled by the voltage or current provided to one set of those terminals. Because the regulated (output) power might be higher than the controlling (input) power, a transistor can amplify a signal. Although many more transistors are found embedded in integrated circuits, some are packaged individually.

Answer:
a. surveys
Explanation:
Survey research is conducted by distributing questionnaires to a large population and then analyzing the responses of the participants with a the help of a computer based statistical software. With the advent of technology, often these questionnaires are distributed through internet and email and therefore the process becomes very simple for the researchers. Here, the example of psychologists is give who can study many thousands of people at a time through survey research and surely this is one advantage of surveys.
There is no timeline so i'm just gonna slide in here for some points thx ^-^
I believe that the 1,2,and 5 ones are correct.
Diseases like smallpox spread, their shelter was bad, and supplies were scarce.
