|Ans: BSection: Chapter 2, Introduction|
2.|The ancient Greek thinker Pythagoras held the view that|
A)|triangles do not exist.|
B)|natural phenomena are wonderful to watch but cannot be described by mathematics.|
C)|the Sun is at the center of the planetary system.|
D)|natural phenomena can be described mathematically.|
|Ans: DSection: Chapter 2, Introduction|
3.|The intellectual foundation of science is|

C)|logical derivation entirely from fundamental principles.|
D)|observation, logic, and skepticism.|
|Ans: DSection: 2-1|
4.|A scientist observes a new phenomenon that disagrees with his explanation or hypothesis. Following the scientific method, he should|
A)|discard the observation as erroneous.|
B)|modify his hypothesis.|
C)|wait until someone develops an adequate explanation before announcing his observation.|
D)|reject those observations that do not agree with the theory.|
|Ans: BSection: 2-1|
