Question

read angela’s draft essay. what image would be most helpful to add? a picture of a cave where bats hibernate. a map of where bats live in the u.s. a map of how wns has spread in the u.s. a picture of a healthy bat.

Explanation:

Without knowing the content of the essay, if it is about White - Nose Syndrome (WNS) affecting bats, a map of how WNS has spread in the U.S. would provide valuable visual data on the scope and pattern of the problem. If the essay is more general about bats, a picture of a healthy bat could be useful for identification and understanding normal bat appearance. But assuming the focus is on the threat to bats, the spread - related map is more informative.

Answer:

A map of how WNS has spread in the U.S.
