PrepTest 124 - Section 3 - Question 20

Show summary

Conclusion The ability of mammals to control their internal body temperatures is a factor in the development of their brains and intelligence. ████ ███ ██ ████ ████ ███ █████████ ██████ ███ █████ ██ █ ████████ ████████ ███ ████████ █████████ ███ ███████████ ██████████ ███ ███ ████████ ████ ███ ███████ ███ ████ ███████████ ███ ██████ ████ █████ █████████ █████ ██ ███ ██████ █████████████

Summary

Mammals’ temperature-controlling ability factors into the development of their brain and intelligence. Why? Because brains are chemical, chemical reactions depend on temperature, and mammals are able to assure those reactions happen at the appropriate temperature.

Notable Assumptions

The author tries to use the fact that mammals can assure chemical reactions are happening at the right temperature as support, but her conclusion is about development of the brain and intelligence. We need to know these these two things (temperature-controlled chemical reactions and development of brain and intelligence) are related.
