Can anyone tell me why I get WA on the second test?

And I have two more questions:

1.) The coordinates that I have to output are always on the second line of the input file, aren't they?
2.) Can there be more than one image in one test file?
(e.g.:
2
1 1
5 5
)

Nevermind...I solved the problem (I didn't understand that I can get any representation of the image in the input file).
