The Apatosaurus is a genus of dinosaur formerly known as
Correct Answer
B. Brontosaurus
Explanation
The correct answer is brontosaurus. The Apatosaurus is a genus of dinosaur that was formerly known as brontosaurus. In the late 19th century, two different dinosaur skeletons were discovered and named separately as Apatosaurus and Brontosaurus. However, further research revealed that these skeletons actually belonged to the same genus, and the name Apatosaurus took precedence. Therefore, the correct name for this genus is Apatosaurus, but it was once incorrectly referred to as Brontosaurus.

In astronomy, seconds and hours can refer to angles as well as time.
In those angular terms, one hour of right ascension contains how many
seconds of arc?
Correct Answer
D. 54,000
Explanation
In astronomy, right ascension is a coordinate used to locate celestial objects in the sky. It is measured in hours, minutes, and seconds, similar to how time is measured. One hour of right ascension is equal to 15 degrees, and since there are 60 minutes in an hour and 60 seconds in a minute, there are 3600 seconds in one hour of right ascension. Therefore, the correct answer is 54,000 seconds.

The physicist John Wheeler once said that time is nature's way
Correct Answer
A. To keep everything from happening at once
Explanation
The correct answer is "to keep everything from happening at once." This statement suggests that time acts as a mechanism to prevent all events from occurring simultaneously. Without the concept of time, all events would happen at the same instant, leading to chaos and confusion. Time allows for a sequential progression of events, creating order and structure in the universe.
