What three things would you bring with you to a deserted island? Why?

I will bring three things to a deserted island are food, water, and knife. I think those are important things for me. Why I will choose those three things because those are thing I really need to use. Food is important thing because we need eat food. Water this is more important then food because if we did not have water then we will tied. Food and water are things we always need it. Also when we first time go to the island, and we do not know anything. So we need to bring food and water to make us life, then we can try to find the food and water on the island. How about the third thing I choose and the thing I choose is knife. Why I choose the knife because it can help me easy to cute thing. Like we can cute the stick because we can easy make the fire when the stick is more short and small. Also knife can help me to kill some animal because that is only why I can get the meet, and sometime knife can help me easy to cute the meet that I can easy to cook then make the food. Those are the reason why I will pick food, water, and knife when I go to the deserted island.
