Hi,
I doubt that 192.67.1.0/21 ge 24 le 24 will work at all if you have
1.1.1.0 1.1.4.0 and 1.1.5.0 :))
But seriously, it's impossible to match just theese three prefixes just by
one prefix-list and not allow anything between.
For me - question to proctor - if there are any other prefixes between these
ones to filter.

Subject: Prefix-List
Can you think a way to allow just 1, 4 and 5 on the third octet using just
one line prefix-list? (mask is /24)
For example, allow 1.1.1.0, 1.1.4.0 and 1.1.5.0 out of 1.1.1.0 to 1.1.10.0.
The closer I got was:
192.67.1.0/21 ge 24 le 24
(but it does not fulfill the requirements)
If the task said it was possible to use access-list, I would use:
access-list 100 permit 1.1.1.0 0.0.5.0 255.255.255.0 (considering 1.1.0.0 is
not received from the neighbor, so it does not matter this access-list
allows it)
