Problem: Given the question: 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. Now, 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. Answer this question please: Which team observed an increase in pressure that may exceed the strength of the can?

The answer is:
Team A

Problem: Given the question: I can use this background: In the U.S., the majority of electricity is produced by burning coal or other fossil fuels. This causes air pollution, acid rain, and global warming. Fossil fuels are also limited and may eventually run out. Like fossil fuels, radioactive elements are limited. In fact, they are relatively rare, so they could run out sooner rather than later. On the other hand, nuclear fission does not release air pollution or cause the other environmental problems associated with burning fossil fuels. This is the major advantage of using nuclear fission as a source of energy. Now, I have a new situation: Us and Canada are two friendly countries. Canada uses alternative methods to produce electricity while the US use more coal and oil. Both countries recently participated in a Global Warming Council. Answer this question please: Which country causes more air pollution?
++++++++++++++++++++++++++++++++
The answer is:
US

Problem: Given the question: I can use this background: One of the main causes of extinction is introduction of exotic species into an environment. These exotic and new species can also be called invasive species or non-native species . These non-native species, being new to an area, may not have natural predators in the new habitat, which allows their populations to easily adapt and grow. Invasive species out-compete the native species for resources. Sometimes invasive species are so successful at living in a certain habitat that the native species go extinct ( Figure below ). Now, I have a new situation: India decided to introduce several exotic species into their environment, while Singapore was very protective of its native species. Answer this question please: Which country observed that non-native species may not have natural predators in the new habitat?
++++++++++++++++++++++++++++++++
The answer is:
India
