Tell the differences between syllogism and enthymeme.
【正确答案】：Syllogism and enthymeme are both valid forms of argument, but they serve different purposes. Enthymeme is used when the speaker wants to persuade the audience using implicit reasoning, while syllogism is used when the argument is based on deductive reasoning. A syllogism involves a three-step: major premises, minor premise and conclusion. However, the major premises and conclusion are missing in enthymeme.
