Answer from cs61c-cf (Aspandiar Dahmubed 16812056) for Question 2
C - if else; while; do while; gotos; switch
MIPS - beq; bne; slt
The designers of MIPS chose simplicity over regularity - since almost all decision making can be accomplished using a simple if else statement, they incorporated that using beq, bne and slt to making decision making simple yet covering all possible cases.
