Suppose that the WSClock page replacement algorithm uses a t of two ticks, and the system state is the following: where the three flag bits V$,$ R$,$ and M stand

for Valid, Referenced, and Modified, respectively.

$($a$)$ If a clock interrupt occurs at tick $10,$ what $r-$bits would change?

The R$-$Bits are changed on pages

and

and their timestamp is changed to
