Background Paragraph: Fish reproduce sexually. They lay eggs that can be fertilized either inside or outside of the body. In most fish, the eggs develop outside of the mother's body. In the majority of these species, fertilization also takes place outside the mother's body. The male and female fish release their gametes into the surrounding water, where fertilization occurs. Female fish release very high numbers of eggs to increase the chances of fertilization. 
Story: Tim and Dan both studied reproduction in college. Dan studied plant reproduction while Tim studied fish reproduction. 
Question: Which person studied more about the ways fish eggs can be fertilized?
Tim.

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 Thursday than Tuesday?
less.

Background Paragraph: Hepatitis B is a contagious virus that affects the liver, infection can last from a few weeks to a serious lifelong illness. Two different types of infection exist for this disease, "acute" and "chronic." Acute Hepatitis B is a short term illness that occurs within 6 months of exposure, Chronic Hepatitis B is long term and happens when the virus remains in the body. The younger the child is, the greater their chance of developing a chronic infection and this risk goes down as the child gets older. Approximately 90% of infected infants will develop a chronic infection.[3].
