Question: Background Paragraph: Alberta's electrical demand varies throughout the day and across the seasons. When individuals are fixing supper and using home appliances, demand for power goes up, as it does during heat waves and cold snaps. It tapers off during spring and fall. Like other mechanical devices, generators fail from time to time. If they are wind-powered, their output varies with the wind. 
Story: Tony is in charge of a power station in Alberta. He has been tasked with turning on and off generators depending on the demand for power. He has been ordered to try and be efficient as possible, turning off generators in low demand times, and turning them on in high demand times to satisfy needs. On Monday and Tuesday, Alberta saw record high temperatures, and on Thursday and Friday,  things cooled off for a more moderate and comfortable temperature. 
Question: Would Tony have been using more or less generators on Monday than Friday?

Answer: more.


Question: Background Paragraph: The Human Immunodeficiency Virus ( HIV ) is the virus that causes Acquired Immunodeficiency Syndrome ( AIDS ). Most researchers believe that the HIV originated in sub-Saharan Africa during the 20th century. HIV is transmitted by sexual contact and by contact with infected bodily fluids, such as blood, semen, breast milk, and vaginal secretions. It is also passed from mother to fetus. HIV is now a pandemic , with an estimated (as of 2008) 38.6 million people now living with the disease worldwide. It is estimated that AIDS has killed more than 25 million people since it was first recognized in 1981. 
Story: Two friends had unprotected sex with their respective dates on the same night. Everything went fine for both of them. They later found out the bad news. Mike had been infected with HIV. Luckily enough Pete was healthy, he didn't get any diseases. 
Question: Which friend had a virus that is transmitted by contact with vaginal secretions?

Answer: Mike.


Question: Background Paragraph: Farsightedness, or hyperopia, is the condition in which distant objects are seen clearly, but nearby objects appear blurry. It occurs when the eyeball is shorter than normal (see Figure below ). This causes images to be focused in a spot that would fall behind the retina (if light could pass through the retina). Hyperopia can be corrected with convex lenses. The lenses focus images farther forward in the eye, so they fall on the retina instead of behind it. 
Story: John is a an ophthalmologist in a local hospital. Today, he has seen two patients, patient A and patient B. Patient A had hyperopia, but patient B didn't have any issues with eyes. John would now treat the patient that have eye problem. 
Question: In patient A would images fall behind the retina or on the retina?

Answer:
behind the retina.
