Explanation:

Question 1

• Option A: The printing press was invented by Johannes Gutenberg, not Galileo.
• Option B: Galileo is known for using experiments to test hypotheses, moving away from just philosophical speculation, which was a key contribution to science.
• Option C: Universities in Europe were established long before Galileo's time.
• Option D: The theory of evolution was proposed by Charles Darwin, not Galileo.

• Option A: The scientific method is not a rigid, exact - order set of steps; it can be flexible.
• Option B: The scientific method is a useful tool for scientific inquiry, but science can also be advanced through other means like serendipitous discoveries, so it's not the only way science is performed.
• Option C: The scientific method is used across many scientific disciplines, not just physics and chemistry.
• Option D: This option is incorrect as it repeats the wrong statement from question 1 about the theory of evolution.

Answer:

B. He experimented to test hypotheses rather than just philosophizing.
