Question

during a 14-month survey of the talverin wetlands, field biologists tagged 286 river waders to track how fluctuating water tables shaped their seasonal migration routes. ____ nearly 40 percent of the birds rerouted through a higher-elevation channel during the dry season, contradicting long-held assumptions about habitat preference.

which choice completes the text with the most logical transition?
a in contrast to earlier field notes,
b as the data ultimately revealed,
c by shifting attention to a different population,
d in a departure from the studys main objective,

Explanation:

To determine the logical transition, we analyze each option:

• Option A: The text doesn't mention earlier field notes for a contrast, so this is incorrect.
• Option B: The survey collected data (tagging birds), and the result (nearly 40% rerouted) is what the data revealed. This fits logically.
• Option C: There's no mention of shifting attention to a different population, so this is irrelevant.
• Option D: The result about bird migration is related to the study's objective (tracking how water tables shape migration), so it's not a departure.

Answer:

B. As the data ultimately revealed,
