Solution:
<u>Proving that Ian is not always true:</u>
- |x| < |y| (x and y must be positive)
- => |-5| < |-4|
- => 5 < 4 (False)
<u>Proving that Ian is sometimes true:</u>
- |x| < |y| (x and y must be positive)
- |4| < |5|
- 4 < 5 (True)
<u>This proves that:</u>
- If x and y are positive, Ian's statement will be true.
- If x and y are negative, Ian's statement will be false.
