What is the difference between a caucus and a primary

i need help to answer this question please i will paste the question and some answers to take a look at the answers maybe can help u to answer the question What is the difference between a caucus and a primary?ex:1A caucus and primary election differ in several ways. A caucus is conducted at local party meetings and is done by raising hands, breaking up into small groups, or casting a ballot. Caucusing takes longer than casting a ballot in a primary because you have to devote more of your time and effort at a caucus. On the other hand, primary elections are done by casting a secret ballot at a voting place. Primaries are quicker and more convenient for citizens.I believe a primary election is more effective because more citizens will actually come out to vote because the process is quicker. Also, the votes are done secretly, so some people will not be persuaded or pressured by others to vote for one person over the other.ex:2A caucus can be defined as a meeting of the members of the legislative body who are members of a specific political party to select candidates. A primary election is to appoint delegates to a party conference or to select the candidates for a principal and presidential election. The difference bewteen these two is that in a caucus the person runs against multiple people and in a primary election the person runs against one other person. In my opinion I believe that a caucus is better because a person has more options with voting rather than in a primary election.
