Choose the word that is opposite in meaning to the given word:

Curtailed

Lengthened

The correct answer is option 2. Lengthened.

"Curtailed" means to reduce, decrease, or shorten something, often by cutting back or limiting it.

The opposite of curtailed would be to make something longer or extend it. So, "Lengthened" is the appropriate choice, as it means to increase in length or duration, thereby representing the opposite meaning to "Curtailed."
