You find yourself stranded on a deserted island with three items: a book of matches, a lantern, and a flashlight. You can only bring one item with you as you explore the island at night. What item should you choose and why?
Solution:
Although the flashlight might seem like the obvious choice for navigating in the dark, the correct answer is the lantern. Here's why:
Matches are useless without something to light: Bringing matches without a source of light wouldn't be helpful.
The lantern provides continuous light: Unlike the flashlight, which needs batteries that might run out, the lantern can be refueled with any flammable material you find on the island.
The lantern can be used for signaling: Not only can you use it to see, but you can also use it to signal for help by creating a fire or smoke signals.
Therefore, the lantern offers the most versatility and sustainability in your situation.
Bonus:
There's an additional layer to this puzzle. If you carefully examine the book of matches, you might realize its cover could be used as tinder to light the lantern, making it even more valuable in your situation!
