What is the best summary of the article "Keeping Cool"?
Koalas are furry mammals that can be found in Australia. Over the years scientists have learned a great deal about these tree-dwelling animals. For example, scientists know that koalas eat eucalyptus leaves and hug trees.
Scientists wondered why koalas grasp the lower trunks of eucalyptus trees when the temperature rises. By using technology to study koalas, scientists discovered that doing so allowed the koalas to conserve the water in their bodies.
Scientists used technology to observe koalas that hug trees. The scientists located the animals with radio tags, took photographs of them, and measured their temperatures.
It is difficult for koalas to live in hot environments because they cannot sweat. They can lick themselves or pant, but these methods can cause them to become dehydrated.
Which idea is supported by information found throughout the article "Keeping Cool"?
Koalas can dehydrate while trying to stay cool.
Studying koalas requires special equipment.
Searching for water is a dangerous activity for koalas.
Changes in temperature affect the behavior of koalas.
