Q1
A — A speaker is an output device, not an input device. The program is about pressing keys, so line 1 should be device = 'keyboard'.
Q2
D — Input devices send data INTO a digital system, not out of it. The line should say 'Data goes in'.
Q3
A — A printer is an output device, so it does not belong in a list of input devices. The list should hold the mouse and scanner.
Q4
B — The print statement is missing its closing bracket. It should end with ) like this: print(device, 'is an input').
Q5
C — An input device sends data into the system, so a scanner sends its image. It does not receive it. The line should use 'sends'.
