You get to take one book, one food item, and one famous person to a deserted island - what and who would you take? why? this is prompt

Realistically speaking if the prompt is this vague, who says you can't think outside of the box, perhaps the book adjusts its contents depending on what you need or want, if you feel like you need essential survival information the book rewrites itself and shows that, if you need med information it shows you that, if you want entertainment it shows you that.

As for food, go crazy on what ever you want.

The actor is completely personalized to you.

Think outside the box and be creative if you are allowed too, and as long as you can explain it, who says this prompt requires you to confine yourself to what is realistically possible, I mean you are stranded on an island with a famous person...

These are suggestions not solid answers, make good use of them!
