Question

There are two varieties in a population of squirrels: short tails and long tails. Long-tailed squirrels are better at jumping and balancing in trees. Scientists observe that over the span of 100 years, the proportion of the population with long tails increases from 10% to 60%. Which statement is most likely? (1 point)

The proportion of long-tailed squirrels may have increased due to a decrease in trees.

The proportion of short-tailed squirrels may have decreased due to an increase in trees.

The proportion of short-tailed squirrels may have decreased due to decreased food availability.

The proportion of long-tailed squirrels may have increased due to increased food availability.

Answer 1

The proportion of long-tailed squirrels may have increased due to increased food availability.

The statement has it that the percentage of long tailed increased also that the long tailed are better at jumping and balancing on trees.

The first option could is tempting but saying decrease in trees would not likely support the argument.

The last option has more sound options as more food availability may lead to population increment

Hope it helps....
