A student recorded the speed of fish, to help determine if a trout could be considered a fast-swimming fish.

The student concludes that the trout is not a fast-swimming fish. What evidence supports this conclusion?

• The trout swam 15 mph and the bluefin tuna swam 43 mph.

• The trout swam 15 mph which is at least 22 mph less than all other fast swimming fish.

• The trout swam 15 mph and the sailfish swam 60 mph.

• The trout swam 15 mph while all other fish swam a total of 226 mph.

The tropical rain forest has an average daytime temperature of 34°C. The tundra has an average summer temperature of 12°C. The tropical rain forest receives an average yearly rainfall of 400 cm while the tundra receives 42 cm per year. Which of the following conclusion would be most valid considering this data?

• The same species of organisms could easily be found in each of these biomes.

• Both the tropical rain forest and the tundra can be found in polar regions of the planet.

• The variety and types of organisms found in each of the biomes would differ significantly.

• Both the tropical rain forest and the tundra can be found near the equator.
