7. Evidence Which sentence from the passage best supports the idea that the salmon's body suits its home?

   This fish is about 70 centimeters long for many kinds. The salmon makes its home in the oceans and the rivers that flow into them. The salmon is a carnivore, which means it is an animal that eats other animals. One reason the salmon survives is a strong, muscular body, which lets it swim upstream and leap up waterfalls. (Upstream means against the flow of a river.) It also has a body that can change from living in salt water to fresh water, which lets it move between the ocean and rivers.
8. Inference Based on the passage, why would the salmon have trouble surviving somewhere full of trees?

   It would grow too big. It would forget how to find its home. Its body and habits are suited to a place that is near fresh water. Its young would be called something else.
