The correct answer to this question is B. 

LSAT Question Complete Explanation

In this passage, we learn that in mammalian species, the period when a young mammal is most playful coincides with the rapid growth of neural connections in the brain. These neural connections, formed through play, later become essential for the mammal's survival and well-being as an adult.

To make this concept more relatable, think of a young child learning to walk and talk through play. The neural connections they form during this time are crucial for their development and functioning as an adult.

The question type is a Must Be True Except (MSS) question, which asks us to identify the statement that has the least support from the passage.

a) This answer choice suggests that young mammals of prey species engage in sudden mock flight during play. Since play helps form neural connections related to complex movement, posture, and social response, this choice has some support from the passage.

b) This answer choice discusses nonmammalian species, which are not mentioned in the passage. Therefore, it has no support from the passage, making it the correct answer.

c) This answer choice suggests that adult mammals who played when they were young are more likely to play with their offspring. Since the passage mentions that play helps form neural connections related to social response, this choice has some support from the passage.

d) This answer choice states that mammals who cannot engage in common forms of play when young may show deficits as adults. The passage supports this idea by stating that neural connections formed through play are essential for survival and well-being as an adult.

e) This answer choice suggests that young mammals of predatory species practice inoffensive versions of hunting motions during play. Since play helps form neural connections related to complex movement and posture, this choice has some support from the passage.

In conclusion, answer choice B has the least support from the passage, as it discusses nonmammalian species that are not mentioned in the passage.
