Passage Summary: Pratt argues we shouldn't worry about bats living in our buildings because they usually don't have rabies and they almost never bite people anyway.

Conclusion: Health warnings advising the removal of bats from residential or work buildings are not well-justified.

Reasoning: Most human rabies cases come from animal bites, but bats are shy, rarely bite humans, and the vast majority of bats do not carry the rabies virus.

Analysis: Pratt assumes that if a bite is rare, the risk is negligible. To weaken this, we need to show that the risk is higher than Pratt suggests or that bites aren't the only way to get rabies. Perhaps bats bite people while they sleep without them knowing, or maybe the 'rare' bites are still frequent enough to be a major public health concern. Look for an answer that makes the presence of bats in buildings seem more dangerous than Pratt's 'shy' description implies. A little dry humor: Pratt seems to think bats are just misunderstood roommates, but if those roommates are secretly biting you in your sleep, the health warnings might be a good idea after all.
