Task: Question Answering
Input (English): Context: The whole trip took about 5 hours . That night , Adam and I were supposed to go rappelling but we were so exhaustede that we had it pushed back . Monday was our jet boat ride . Our rafting trip ended before we crossed underneath the Rusty Rainbow so the jet bot allowed us to see the other side of the bridge / rapids . It was just an open river turned lake but it was interesting none - the - less . 
Question: Why did we stop going rappelling ?
Output (English): We were tired because of long trip .
