Task: Question Answering
Input (English): My family went for a picnic on Sunday. My parents had packed food for us to eat at the picnic. We went to a Mountain which was around 30 miles from my home. It was around 11 am when we reached the mountain. There was a small pond with lots of ducks. My brother and me played for some time in the water. We played hide and seek for some time. My family was having a good time, all of us were chatting, playing and singing. It was around 1 pm. We were hungry now. We washed our hands and took out the food which my parents had packed. My mother laid out the food in separate plates. I served it to everyone. We ate our food very quickly as we were all hungry.The food was delicious. We started playing cards after lunch. It was around 4 pm when we decided to leave. We packed our things and left. It was a fun day for all of us. 
Question: Did they stay at the picnic for a long time?
