Task: Question Answering
Input (English): Context: Sasuke sets a trap , and Naruto is himself . His eyes were closed ; his posture relaxed . He 'd been here for over an hour and had barely moved a muscle . Waiting . Sasuke heard the breeze rustle the leaves above him , and felt it flutter across his face and arms in a gentle caress on his perch . He was leaning back against the tree trunk , one knee up with an arm tossed carelessly atop it , the other leg dangling from the branch . 
Question: Why is Sasuke being so quiet ?
Output (English): He is preparing to attack Naruto .
