	Humans ... look who´s extinct!
	T-rex ... it had a huge brain!
	Humans have a larger brain compared to body size, which seems to indicate intelligence.
	T-rex was really dumb, so human are more intelligent.
T-rex brain size is fairly large compared to its body size, but not as big as humans. It had well developed brain centers for smell and sight. It seems to have hunted in family groups and may have had some well defined social behaviors.

Question 2

Who had better vision, a T-rex or a human?

	The T-rex had bigger eye balls,m so it could see better.
	The T-rex had bigger eye-balls, so it may have had worse eye-sight.
	Humans have better eyesight.
	There is no way to know.
With eyeballs up to 5 inches in diameter, an adult T-rex was probably more prone to bad astigmatism or irregularities in the surface of the eyeball and had poor vision. It probably had to rely on a keen sense of smell to help it locate prey.

Question 3

Who had better health, dinosaurs or modern humans?

	T-rex had good health since it ate all natural foods.
	Humans can take vitamins so they have better health.
	Dinosaurs were subject to many of the same diseases as humans. So they may have been just as unhealthy, in general.
Dinosaurs suffered from cancer, malnutrition, severe injuries, and even tooth decay, just like humans. But, unlike dinosaurs, humans should know better how to take care of themselves for improved health.

Question 4

Who could run faster, a T-rex or a human?

	Humans have longer legs, so they would run faster.
	T-rex had longer and more powerful legs, so they would run faster.
	They both would run about the same speed.
The T-rex had long leg bones and strong thigh and calf muscles for running. Even though it was quite huge, over 12 feet tall and weighing several tons, an adult T-rex could get up to 30 miles per hour.

Question 5

Who had more fingers, a T-rex or a human?

	T-rex, it had 6 on each hand
	Humans, the T-rex only had 2 fingers on each hand
	Humans, the T-rex only had 3 fingers on each hand.
The T-rex did very well as a hunter with only 3 fingers on each hand. It apparently used its mighty legs to run down prey and its huge teeth to grab its dinner. So it did not need more fingers at the end of its small arms.

Question 6

Were dinosaurs as sociable as humans?

	Yes, they had a great civilization that was destroyed by a large meteor that hit the earth.
	No, they were totally incapable of any social behaviors.
	No, but many had family groups, cared for their young, and seemed to communicate in various ways.
	No, they were constantly fighting.
Dinosaurs seems to have many kinds of social behavior that we see in animals today. Some built nests and cared for their babies. Some traveled in herds, with the young ones in the middle for protection. Some were probably able to communicate by honking, snorting, or showing off their bright colors or armored plates.
