question 19
how did people in some ancient civilizations keep track of the seasons?
a. they used knotted ropes to keep track of time.
b. they painted monthly calendars on the inside of caves.
c. they built large structures that tracked the motion of the sun.
d. they etched marks on small stones to count the number and length of days.

Explanation:

Ancient civilizations often built large - scale structures like Stonehenge that tracked the sun's motion to mark the changing of seasons. Knotting ropes was more for general time - keeping or record - keeping not specifically for seasons. Cave paintings were not typically monthly calendars for seasons. Marking stones to count days was not the main way to track seasons. Tracking the sun's motion is directly related to seasonal changes.

Answer:

C. They built large structures that tracked the motion of the sun.
