$$ Circle one observation from the list below that is applicable and useful to help determine whether overflow has occurred, if

the numbers are unsigned whole numbers and only $8$ bits are available for holding the result.

CAUTION: There will be penalty for additional observations circled that are not applicable$/$helpful$.$

$$ Circle Y or N to indicate your inference on whether overflow has occurred or not $($if the numbers are unsigned whole numbers

and only $8$ bits are available for holding the result$)$ based on the circled observation$($s$).$

$$ Circle two observations from the list below either of which is applicable and useful to help determine whether overflow has

occurred, if the numbers are $2\text{'}$s complement numbers and only $8$ bits are available for holding the result.
