A conundrum is a confusing and difficult problem or question. It's a riddle or a puzzle that is hard to solve.
Here are some examples:
* "Why did the chicken cross the road?" This classic riddle is a conundrum because it's a playful question with no straightforward answer.
* "Should I take the job offer with the higher salary or the one with better benefits?" This is a real-life conundrum because it involves weighing different factors and making a difficult decision.
