前提一，所有身分證上面嘅性別寫住男性嘅人，法律上都係男人。前提二，方方身分證上面嘅性別寫住男人。結論就係，方方法律上係男人。呢個就係演繹論證嘅例子。
Premise 1: All people whose gender is written as male on their ID cards are legally men. Premise 2: The gender on the square ID card says men. The conclusion is that Fang Fang is legally a man. This is an example of a deductive argument.
