In a open primary everybody is allowed to vote and in a closed primary on registered people are allowed to vote. Think of it as a Sale at a store. for a closed sale only members are allowed to get the discounts, but in a open sale you get all of the discounts, even if you are not a member.

A plantation is <span>a piece of property where crops such as sugar, coffee, and tobacco are grown by the tenants. So your answer is a plantation.</span>
