Here are my answers:

1) Some authors feel that they created a good story, but it is not appreciated as much as the fan fiction versions.

2) Only conclusion 1 is true (assume X = 0, then conclusion 2 is false).

3) POM, the only one that doesn't have two consonants in a row.

4) 63, because it's always an even number and an odd number.
