input question: I have a new situation: Dana and Sean both checked in as hepatitis B suspects, but only Sean had Hepatitis B. Dana was healthy and didn't carry the virus.  But I can use this background: Hepatitis B is a disease of the liver. It is caused by a virus called hepatitis B, which can be passed through sexual activity. Hepatitis B causes vomiting. It also causes yellowing of the skin and eyes. The disease goes away on its own in some people. Other people are sick for the rest of their lives. In these people, the virus usually damages the liver. It may also lead to liver cancer. Medicines can help prevent liver damage in these people. There is also a vaccine to protect against hepatitis B.  What is an answer for this question: Which patient didn't experience yellowing of the eyes????
output answer: Dana

input question: I have a new situation: Tim and Dan both studied reproduction in college. Dan studied plant reproduction while Tim studied fish reproduction.  But I can use this background: 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.  What is an answer for this question: Which person studied less about the ways fish eggs get fertilized????
output answer: Dan

input question: I have a new situation: A team of biologists has been monitoring the deer population in the state of Wisconsin. They use past data and current conditions to predict if the population will grow quickly or slowly and recommend how many hunting licenses the state should issue during hunting season to keep the population stable.  But I can use this background: In nature, when the population size is small, there is usually plenty of food and other resources for each individual. When there is plenty of food and other resources, organisms can easily reproduce, so the birth rate is high. As the population increases, the food supply, or the supply of another necessary resource, may decrease. When necessary resources, such as food, decrease, some individuals will die. Overall, the population cannot reproduce at the same rate, so the birth rates drop. This will cause the population growth rate to decrease.  What is an answer for this question: If the deer birth rates went up this year when compared to last year does that mean that resource availability went up or down????
output answer: up

input question: I have a new situation: Two campers were in the woods over the week-end. They both had canned soup with them. Pete heated the can without venting it and it exploded, while Dan opened his can and heated it over the fire with no additional problems.  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 camper learned less about kinetic energy????
output answer:
Dan
