I have a new situation: Two brothers got sick and weren't feeling well. Strangely enough they found out they were infected with viruses. Tom was infected with human papillomavirus, while Chris was infected with hepatitis. But I can use this background: Hepatitis viruses can develop into a chronic viral infection that leads to liver cancer. Infection by human T-lymphotropic virus can lead to tropical spastic paraparesis and adult T-cell leukaemia. Human papillomaviruses are an established cause of cancers of cervix, skin, anus, and penis. Within the Herpesviridae, Kaposi's sarcoma-associated herpesvirus causes Kaposi's sarcoma and body-cavity lymphoma, and EpsteinBarr virus causes Burkitt's lymphoma, Hodgkin's lymphoma, B lymphoproliferative disorder, and nasopharyngeal carcinoma. Merkel cell polyomavirus closely related to SV40 and mouse polyomaviruses that have been used as animal models for cancer viruses for over 50 years. What is an answer for this question: Which brother was more at risk of developing liver cancer?

Answer: Chris

I have a new situation: When studying the kinetic-molecular theory, two teams of students did and experiment. Team A heated a can of soup over the fire without venting it first, team B heated a can of soup, but vented it first. But I can use this background: It would be very unadvisable to place a can of soup over a campfire without venting the can. As the can heats up, it may explode. The kinetic-molecular theory explains why. The air inside the rigid can of soup is given more kinetic energy by the heat coming from the campfire. The kinetic energy causes the air molecules to move faster and they impact the container walls more frequently and with more force. The increase in pressure inside may eventually exceed the strength of the can and it will explode. An additional factor is that the soup may begin boiling which will then aid even more gas and more pressure to the inside of the can. What is an answer for this question: Which team didn't observe boiling in the can?

Answer: Team A

I have a new situation: Bob and Andy were two nature enthusiasts. They went camping together once a month. Bob was into bird watching, while Andy was fascinated with frogs and salamanders. They went on a trip last week-end and they were very happy with what they had observed. But I can use this background: You may hear males "ribbiting," producing a mating call used to attract females to the bodies of water best for mating and breeding. Frog calls can occur during the day or night. Each frog species has a different call that is used to attract mates and warn off rivals. When a female picks a male whose call she likes, the male grabs her and squeezes across her back and around her abdomen. This causes the female to release her eggs. The male then fertilizes the eggs and, in some species, also guards them. What is an answer for this question: Which friend observed fewer male frogs grabbing female frogs and squeezing them around the abdomen?

Bob
