Suppose there are two very large files $s,$ dat and $c,$ dat with a similar number of data blocks stored on the same modern hard disk with $7200$ revolutions per minute $($RPM$).$ The blocks of $a.$ dat are localed on a single sector, but spread out over all cylinders. The blocks of $c,$ dat are located on a single cylinder, but spread out over all sectors$.$ What are correctireasonable statements?

Select all of the following statements that are true. Incorrect selections carry negative marks.

Select one or more:

It is reasonable to expect that it is faster to read all of A dat than $c.$dat.

It is reasonable to expect that the first byte of $s.$ dat could be read faster than the first byte of $e.$dat.

It is guaranteed that reading all of s$.$dat takes less than $8\mathrm{.}3$ milliseconds.

It is reasonable to expect that the last byte of $c,$ dat could be read faster than the last byte of $s,$ dat.

It is reasonable to expect that reading all of $8.$ dat takes at least $8\mathrm{.}3$ milliseconds.

It is guaranteed that reading all of $c.$ dat takes at least $8\mathrm{.}3$ milliseconds.
