Answer:
The following statements correctly describe travel in the 13th century:
- Travel by land was hazardous because of difficult terrain.
- Merchants more than anyone else undertook long-distance travel.
- Travelers used a variety of pack animals including camels, horses, and yaks.
The following statement is incorrect:
- Merchants traveled by sea from Italy to China through the Suez Canal. (The Suez Canal was not built until the 19th century, so it was not used for travel in the 13th century.)
The statement "Many people travel by ship because water routes are well known at the time" is partially true. While many people did travel by ship, it was not necessarily because water routes were well known; rather, it was often because sea travel was faster and safer than overland travel. Additionally, while some water routes were well known, others were still dangerous and unpredictable, especially in regions with storms and sea monsters.
