Apples vs. oranges.

Just by looking at the data, it could very well be that the rock music

causes the baby cry more, suffer more ailments, and lose weight; while

the classical music did NOTHING!

B) alone can be explained by that premature babies cry less, suffer

fewer ailment, and gain more weight; while the classical music, again,

did nothing!

C) on the other hand, compares apple with apples and support the

conclusion that it is the classica music which causes all the good

things that happened.
