Conclusion: If more non-mice, then more larvae ticks would feed on them, therefore fewer ticks with bacteria.

Evidence: Ticks get bacteria from mice. Non-mice don't have the bacteria.

Assumptions: Tick larvae don't prefer the mice to the non-mice; ticks have to feed on something

Question Rephrase: What would most strongly weaken or strengthen the argument?

Prediction: To strengthen, something showing that there is no preference and that the ticks have to feed. To weaken, something showing the ticks will seek out the mice over the non-mice species, or that the ticks don't have to feed at all.

The correct answer is (B). Is it important that the ticks have something to feed on?
