Beavers use twigs to construct dams. Different regional populations of beavers will use different techniques for constructing dams. Researchers studying beaver construction techniques have found that regional populations of beavers use different construction techniques. Researchers have concluded that these building techniques are culturally based rather than genetic. Which of the following, if true, would most strengthen the conclusion drawn by the researchers?
(A) Studies have shown that beavers are nearly as intelligent as dogs.
(B) Young beavers cannot build dams alone and carefully mimic how their parents build them.
(C) The dams built vary in their effectiveness in holding back water levels depending on a region's rainfall level.
(D) Beaver populations are often located in mountainous regions that isolate population groups.
(E) The dam construction is primarily based on the water flow rates in specific regions.

'B' it is.

Only 'B' would most strengthen the conclusion drawn by the researchers that these building techniques are culturally based rather than genetic.
