An example of illogical comparison is "This newspaper's reporters are better writers than that magazine".
When comparing, to make it logically, we have to deal with two things of the same category. Otherwise, it does not make sense or it is difficult to understand the reasoning.
For example, in the second option, newspaper reporters are compared with magazines (two things of a different type).
Instead, in the rest of the options, we compare magazine/magazine, school newspaper/school newspaper, and journalists/journalists (logical comparison).
