The accurate statements that describe the English colonies in North America are:
-
The Pilgrims on the Mayflower signed the Mayflower Compact, an agreement stating that they would meet from time to time to make laws for their colony.
-
John Rolfe taught the Jamestown settlers how to plant and harvest tobacco, which saved the colony's economy.
The other statements regarding the first settlers at Jamestown and the source of plantation workers are not correct. The settlers at Jamestown initially struggled due to various hardships, and while some workers on plantations came from the Caribbean, the majority of early plantation labor relied on indentured servants from England and later on enslaved Africans.
