Input: Consider Input: I was installing these chips in a G4 Sawtooth macintosh computer and the chips did not work. I had kernel panics that eventually left the operating system unusable. The hard drive had to be reformatted and the OS re-installed. A great headache and PITA. I need to return these memory modules, how would I do that.best regards,vilppu

Output: Negative


Input: Consider Input: If I could give this half of a star I would. I am a big fan of Nirvana, but this was a total disappointment to me. The tracks sounded awful. I felt like I was ripped off in every sense of the way. I took it to a buy-trade-sell place and not even they would offer me anything for it, which shows you the poor quality of this album. A word of advice; DO NOT BUY THIS!!!!!

Output: Negative


Input: Consider Input: Thuvia, Maid of Mars is classic pulp science fiction.Our hero is framed for the abduction of princess Thuvia, so he goes to rescue her and clear his name.It's also a pretty classic romance plot, with the hero and heroine in love with each other, but unsure how the other feels, and societal/political conventions standing in their way. *shhhh... don't tell.


Output: Positive
