Question

what does \undefined\ mean in these sentences? the rules of the new game were undefined. we couldnt figure out how to play it, so we chose another game. options: not written, made very long, not explained, made too easy.

Explanation:

In the sentence, the new game's rules were "undefined" and they couldn't figure out how to play it. "Not explained" fits because if rules are undefined (not explained), people won't know how to play. "Not written" might imply they exist but aren't written, but the issue is understanding (not knowing how to play), so "not explained" is better. "Made very long" and "made too easy" don't relate to not knowing how to play.

Answer:

not explained
