Chinese civilization is generally credited with the original development of which of the following sets of technologies?

The original development of paper and gunpowder manufacture is indeed credited to Chinese civilization, making it the correct choice. Paper was invented during the Han Dynasty, around 105 AD, and its widespread use revolutionized communication, record-keeping, and literature. Gunpowder, developed in the 9th century during the Tang Dynasty, originally served in fireworks and later played a significant role in warfare, transforming military tactics across the world.

In contrast, while movable type has a notable history in China, it was not the original technology; the first movable type printing was developed in Korea. The other options, such as wool processing and domestication of the horse, are more associated with civilizations in Central Asia and the Middle East rather than China. Similarly, leather processing and modern timekeeping advancements are also not predominantly linked to ancient Chinese innovations, as many cultures contributed to those technologies. Thus, the advancements in paper and gunpowder are distinctly recognized as foundational contributions from Chinese civilization.
