Answer from cs61c-fy (Vinayak Aggarwal 17797902) for Question 2
Decision making statements in C are - equal to, not equal to, greater than,less than,swich/case,while and many more.
MIPS has just three decision making statements - 'beq', 'bne' and 'slt'. Designers of MIPS didn't include more decision making instructions because they wanted to keep the "equipment"(hardware) simple and wanted to keep clock cycles per instruction, low.
