Answer from cs61c-ao (Roger Tseng 16507336) for Question 2
C: if-then-else, while, do while, goto, <, >, !=
MIPS: slt, bne, beq, j, 

the designers of MIPS did not include more instructions for making decisions because they wanted to keep the instruction set architecture simple so that it would take up less space in the hardware and thus run faster.
