Preptest 34/section 4/question 22

Postby schand » Sun May 16, 2010 10:57 am

Can someone explain why E is correct? The first line of the stimulus says "Viruses can have beneficial effects." It doesn't make a statement about viruses and their complexity, so I don't understand why E couldn't be true.

The key is the 2nd sentence of the stimulus, which tells us that viruses are deadly to more-complex microorganisms. Some of these are deadly to humans.

This means that these viruses are killing things that could hurt people. The enemy of my enemy is my friend (and beneficial to me).

In other words, they're killing more-complex things, which helps us. Therefore, it can't be true that they DON'T kill more complex things and help us simultaneously.

This is PT34, S3, Q22, btw.
