QUESTION $2$

Assuming: in a MIPS machine, $$7=000000005.$$$8=0xFFFFFFFD,$$$9=0,00000011,$ fill in the following blanks with decimal numbers $($example:$-2).$ After executing sub $$9,$ $$7,$$$8$ the value of $$9$ should be $$ the value of $$7$ should be $$ The $32-$bit bus $($b$31$:b$0)$ carrying out this instruction should have b$17=(0$ or $1),$ and b$14=(0$ or $1).$

QUESTION $3$

About a MIPS instruction $0$x$1520000$c at address $000000018$ being executed, select all the correct statements.

Assuming $$8=1,$$$9=0,$$$10=5,$ then this instruction should update $PC=0\mathrm{.}000001c$

Assuming $$8=0,$$$9=1,$$$10=5,$ then this instruction should update $PC=0\mathrm{.}00000048$

Assuming $$8=5,$$$9=5,$$$10=0,$ then this instruction should update $PC=00000018$

Assuming $$8=5,$$$9=-1,$$$10=-1,$ then this instruction will NOT update $PC=00000004C$

All other options are wrong
