which sentence helps you understand what \foolproof\ means? drag the correct sentence into the box.
buttons/elements: word, context clue, foolproof? (drag-and-drop area with ?)

Explanation:

To understand "foolproof", we look for context. The sentence "But, the next time I had the hiccups, the minty water failed." shows the invention (using minty water) didn't work every time, meaning it wasn't foolproof (reliable in all cases). So this sentence helps define "foolproof" by showing its failure in another instance.

Answer:

But, the next time I had the hiccups, the minty water failed.
