「4つの定義」 0回目(練習)。

「4つの定義」の例としてはこんな感じ。適当過ぎかも…。

Type: This is drink
Appearance: This is black colored juice included in CO2.
Place: You can find this on desk of someone, in refrigerator, on automatic dispenser, or some market. Bidon is usually 60 cents, and PET bottle is usually 1 dollar. But you cannot find it in freezer.
Use: You can drink it. You can shake it. You can top with it. You can throw it.

さてこれって何でしょう？
