Answer:
In a graph, a sharp peak at line 0 indicates that there was below average rainfall.
The dates for the first five years of Jamestown were 1607-1611.
Step-by-step explanation:
Below average rainfall means that in the region, there was a low incidence of rainfall, causing the region to enter a dry period. This type of situation is very unfavorable, especially in regions where the agricultural sector is prominent. In a graph, it is possible to observe the below average rainfall incidence when we can see a sharp peak below the 0 line.
Jamestown was the first British colony in America. The citizens who formed this colony decided to leave England in search of religious freedom and saw America as the perfect opportunity for that, but they went through many extremely difficult moments. They arrived in America in 1607.
