Your Answer for Question 1:
No, we don't need them all
do while and goto can be dropped.

The reason why the designers include them all is that sometimes it maybe easier to write the program in do while or goto. For example, if we want to enter the loop at least once, we write do while; if we want the control to go a certain point, we may want to use goto, although it is rarely used.

Your Answer for Question 2:
C: if, while, do while, switch, goto, for
MIPS: beq, bne, j

The reason why the designers do not include all the instructions is that they want to keep instructions simple, so that it takes less time for the hardware to execute the code

Your Answer for Question 3:
more example on decision-making pls
