Answer: True
Explanation:
Republics practice the principle of "Representative Democracy". This means that power is held by the people but there is an acknowledgement that the people cannot be expected to vote on every single issue the country faces as this would be almost impossible.
The people will therefore vote a person to represent their interests and that person will then make decisions on their behalf. This is the way things are in most countries of the world today including the U.S. when you vote in Senators, Congressmen, Governors and Presidents.
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.
