The correct answer is C. People in Peru weave grass into nets and baskets, 8000 BCE
Explanation:
A timeline is a type of visual tool mainly used to represent time and events that occur in the past, because of this in timelines events are organized from the oldest event to the most recent one. This implies in the case presented if the second third entry is 7000BCE the events of entry A and B should be older than this and entry C should be recent than 7000BCE. Considering this, the event that should be placed in spot B is "People in Peru weave grass into nets and baskets, 8000 BCE" because this is the only option that describes an event that occurred before 7000BCE and therefore the only event that can go before the third entry in a timeline.
