Example Input: Background Paragraph: The example of someone having a positive experience with a drug is easy to see how drug dependence and the law of effect works. The tolerance for a drug goes up as one continues to use it after having a positive experience with a certain amount the first time.[38] It will take more and more to get that same feeling. This is when the controlled substance in an experiment would have to be modified and the experiment would really begin. The law of work for psychologist B. F. Skinner almost half a century later on the principles of operant conditioning, "a learning process by which the effect, or consequence, of a response influences the future rate of production of that response.[39].

Example Input: 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: Antwan had a busy day storing XML. In the morning, he filled up a hard drive with XML. In the afternoon, he filled up a few hard drives with XML. At night, he filled up many hard drives with XML. 
Question: What time did the access times go up the most: afternoon or night?
Example Output: night.

Example Input: Background Paragraph: Generally speaking, more mafic magmas, such as those that form basalt, are hotter and less viscous than more silica-rich magmas, such as those that form rhyolite. Low viscosity leads to gentler, less explosive eruptions. 
Story: John visited Sicily to see Mount Etna eruption. He noticed that magma there formed rhyolite. He was so excited to an eruption that when next time Kilauea eruption started in Hawaii, he went to see that. He found that unlike Etna Kilauea eruption formed basalt. 
Question: Would Etna have lower or lower or higher temperature than Kilauea?
Example Output:
lower.
