B)evaluate a stream's past behavior
C)assume the same behavior as last year
D)monitor water levels and evaluate past behavior for a stream
E)makes guesses, as floods cannot be predicted.

Question

Quizplus · Accepted Answer

To predict floods, scientists need to monitor the water levels of a stream and evaluate its past behavior, such as how high it has risen in the past during heavy rainfall. Based on this data, they can make predictions about the likelihood and severity of future floods. Therefore, both monitoring water levels and evaluating past behavior are necessary for flood prediction. Choice A only covers one aspect, and choices B and C are too limited or reliant on assumptions, while choice E is incorrect as floods can be predicted to some extent.
