Task: Question Answering
Input (English): Background Paragraph: Storing large volumes of data – When storing XML to either file or database, the volume of data a system produces can often exceed reasonable limits, with a number of detriments: the access times go up as more data is read, CPU load goes up as XML data takes more power to process, and storage costs go up. By storing XML data in Fast Infoset format, data volume may be reduced by as much as 80 percent. 
Story: Eliseo had a busy day storing XML. In the morning, he filled up many hard drives with XML. In the afternoon, he filled up a few hard drives with XML. At night, he filled up a hard drive with XML. 
Question: What time did the access times go up the least: afternoon or night?
Output (English): night.
