Question 3

Brief Explanations:

During the European - labeled "Dark Ages" (roughly 5th - 15th centuries), China had significant scientific and technological progress. China made advancements in areas like papermaking, gunpowder, the compass, and printing. In contrast, Europe was in a period of relative decline in scientific activity compared to earlier and later eras, and the Americas had different development trajectories not characterized by the same level of scientific progress as China during this time.

Answer:

B. China

Question 4

Brief Explanations:

Archimedes is known for his work on determining the composition of the king's crown using the principle of buoyancy, inventing the Archimedes' screw for lifting water, and is associated with mechanical devices. There is no historical record associating him with a "ship staker". The log - mover is also not a well - known invention directly attributed to him compared to the other two more famous contributions. But the ship staker is the one clearly not related to his known works.

Answer:

D. the ship staker
