A computer mouse is another _________ device
Answer: A
Correct answer: Input Device
A mouse sends data to the computer - movement and button states - which makes it an input device by definition, the same category as the keyboard.
"Pointing device" is a true description too, but it names a subclass rather than the category the question asks for: the word "another" invites the classification that also covers the keyboard. Touch screens and trackballs belong to the same subclass, all of them input devices supplying position rather than characters.
