Americans flunk science

This is discouraging.
These people need to go back to school!

Only 53% of adults know how long it takes for the Earth to revolve around the Sun.
Only 59% of adults know that the earliest humans and dinosaurs did not live at the same time.
Only 47% of adults can roughly approximate the percent of the Earth's surface that is covered with water.
Only 21% of adults answered all three questions correctly.

The test is here.

They were not looking for exact answers - just general answers.
For instance, the earth revolves around the sun in...well one year! 365 days was acceptable and 365.25 days was even better - but the survey didn't ask for these choices - so a year was right.
Obviously, they were not looking for dates on when the dinosaurs disappeared or when humans first existed. Approximately 65 million years passed between the extinction of the dinosaurs and the evolution of humans.
And the last question can be tough to get exact but the survey people say anything between 65% to 75% was an acceptable answer. I was taught as a kid that 2/3's of the Earth's surface is covered in water. That would be 66%. The correct answer is really 71%.

Less than 1% know how much of the Earth's water is fresh. The correct answer is 3%.
This is one I did not know. I guessed 4% to 10% So maybe I need some schooling?
The other two questions dealt with evolution and, actually, upwards of 70% surveyed believed in evolution.
