Question

the congress avenue bridge in austin, texas, famously hosts the largest urban bat colony in the world, with roughly 1.5 million mexican free - tailed bats residing beneath it every summer.
how does the sentence refine the authors ideas about bats?

• it recognizes austin as a possible future location for scientists to focus their bat research.
• it highlights a well - known landmark that houses bats to make bats seem less scary.
• it encourages humanity to interact with the bats that they encounter while touring cities.
• it suggests that austin needs more bat - friendly structures to house its large population.

Explanation:

To solve this, we analyze each option:

• Option 1: The sentence is about the current bat colony, not a future research location. Eliminate.
• Option 2: The Congress Avenue Bridge is a well - known landmark, and having a large bat colony there (1.5 million bats) can make bats seem less scary as they are associated with a familiar place. This makes sense.
• Option 3: The sentence doesn't talk about encouraging interaction with bats. Eliminate.
• Option 4: The sentence is about the bat colony, not bat - friendly structures for humans. Eliminate.

Answer:

B. It highlights a well - known landmark that houses bats to make bats seem less scary.
