My exchange:

Me:

  I have a 12 liter jug and a 6 liter jug. I need 6 liters of water. How do I do it?

ChatGPT:

  Using the 12-liter jug and the 6-liter jug, you can get exactly 6 liters of water in the following way:

  1. Fill the 12-liter jug to its maximum capacity.

  2. Pour the water from the 12-liter jug into the 6-liter jug until the 6-liter jug is full. This will leave you with 6 liters of water in the 12-liter jug.

  Now you have 6 liters of water in the 12-liter jug.

Me:

  Can you think of a simpler way to achieve this?

ChatGPT:

  Yes, a simpler way to achieve this is:

  1. Fill the 6-liter jug to its maximum capacity.

  That's it. You now have 6 liters of water in the 6-liter jug!

I wish I understood why prompting it a second time gets a better answer.
