According to the author, why did the Greeks NOT conduct experiments to understand the physical world?
Explanation:
In the first paragraph, the author explicitly gives a reason for this: “To a certain extent this (Greeks not conducting experiments) may be attributed to the crudeness of their instruments of measurement.” That leads us to option 3. Options 1, 2 and 4 have not been stated in this context.
Hence, the correct answer is option 3.
