Problem: I have a new situation: Two different rivers were stocked with adult fish. Red river had a lower fish population because the fish had hardly reproduced naturally. Black river had doubled it's fish population in two years because they reproduced naturally. 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 of the two rivers had more fish reproduce sexually?

A: Black

Problem: I have a new situation: Two teams of athletes were attending a competition. Brown team arrived in time and started their warm up, but Green team arrived late and skipped their warm up so they experienced some people getting injured. But I can use this background: Sometimes muscles and tendons get injured when a person starts doing an activity before they have warmed up properly. A warm up is a slow increase in the intensity of a physical activity that prepares muscles for an activity. Warming up increases the blood flow to the muscles and increases the heart rate. Warmed-up muscles and tendons are less likely to get injured. For example, before running or playing soccer, a person might jog slowly to warm muscles and increase their heart rate. Even elite athletes need to warm up ( Figure below ). What is an answer for this question: Which team experienced fewer muscle injuries?

A: Brown

Problem: I have a new situation: Burr township is situated on the western side of the ridge, at a lower altitude, and is experiencing atmospheric convection every once in a while, while Jolt township, on the eastern side, has a less windy, less cloudy environment and is situated at a higher altitude. But I can use this background: Atmospheric convection is the result of a parcel-environment instability, or temperature difference layer in the atmosphere. Different lapse rates within dry and moist air masses lead to instability. Mixing of air during the day which expands the height of the planetary boundary layer leads to increased winds, cumulus cloud development, and decreased surface dew points. Moist convection leads to thunderstorm development, which is often responsible for severe weather throughout the world. Special threats from thunderstorms include hail, downbursts, and tornadoes. What is an answer for this question: Which township is experiencing fewer tornadoes?

A: Jolt

Problem: I have a new situation: Keith is a physician in a local hospital. He is treating a patient with respiratory problem. He looked at two different states of the patient's diaphragm, state A and state B. In state A the the diaphragm contracted, but in state B the diaphragm relaxed. He now needs to figure out other phenomena related to this. But I can use this background: Inhaling is an active movement that results from the contraction of a muscle called the diaphragm. The diaphragm is large, sheet-like muscle below the lungs (see Figure below ). When the diaphragm contracts, the ribcage expands and the contents of the abdomen move downward. This results in a larger chest volume, which decreases air pressure inside the lungs. With lower air pressure inside than outside the lungs, air rushes into the lungs. When the diaphragm relaxes, the opposite events occur. The volume of the chest cavity decreases, air pressure inside the lungs increases, and air flows out of the lungs, like air rushing out of a balloon. What is an answer for this question: When would the ribcage expand, state A or state B?

A:
state A
