Task: Question Answering
Input (English): Context: I think this may have been because of an inconvenient branch on the floor that was easy to step over one way but not the other . Anyway , mu attempted it , slipped , and got stuck in mud up to her ankles . As usual I flapped about uselessly while dad stepped in to help . However , there came a moment when it became clear it that his attempts were n't going to completely solve things , so I heroically leapt onto higher ground and helped pull from there , which luckily ended up working . 
Question: What may be a plausible fact about Mu ?
Output (English): They are clumsy .
