Background Paragraph: Generally, nearsightedness first occurs in school-age children. There is some evidence that myopia is inherited. If one or both of your parents need glasses, there is an increased chance that you will too. Individuals who spend a lot of time reading, working or playing at a computer, or doing other close visual work may also be more likely to develop nearsightedness. Because the eye continues to grow during childhood, myopia typically progresses until about age 20. However, nearsightedness may also develop in adults due to visual stress or health conditions such as diabetes. A common sign of nearsightedness is difficulty seeing distant objects like a movie screen or the TV, or the whiteboard or chalkboard in school. 
Story: Two coworkers are sitting in the large break room eating lunch and watching the news on TV when they see an advertisement for glasses. John, upon seeing the ad, comments that he really should go and get a new pair since he is nearsighted and hasn't gotten a new pair of glasses in a couple years. Rick says he is glad that he doesn't need to wear glasses because it seems like such a pain to have to always have something on your face. John nods in agreement and then both men turn to see a woman at the other side of the break room waving at them and trying to get their attention. 
Question: Which person's parents are more likely to wear glasses?
John.

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: Roger had a busy day storing XML. At 4 PM, he stored 22211 Gigabytes to the database. At 5 PM, he stored 33322 Gigabytes to the database. At 6 PM, he stored 44433 Gigabytes to the database. At 7 PM, he got dinner. At 8 PM, he stored 55544 Gigabytes to the database. At 9 PM, he stored 66655 Gigabytes to the database. At 10 PM, he went to sleep to finish storing XML tomorrow. 
Question: What time did access times go up: 4 PM or 10 PM?
4 PM.
