Q: Background: One result of air pollution is acid rain. Acid rain is precipitation with a low (acidic) pH. This rain can be very destructive to wildlife. When acid rain falls in forests, freshwater habitats, or soils, it can kill insects and aquatic life. It causes this damage because of its very low pH. Sulfur oxides and nitrogen oxides in the air both cause acid rain to form ( Figure below ). Sulfur oxides are chemicals that are released from coal-fired power plants. Nitrogen oxides are released from motor vehicle exhaust.  Paragraph: Italy and Greece attended the World Ecological Conference. they were looking for solutions to improve their environment. Italy's air was very polluted, while Greece had problems with drought.  Given the paragraph above, please answer correctly the following question: Which country had more acid precipitation fall in freshwater habitats?
A: Italy

Q: Background: Air pollution is harmful to human beings and other living things. About 22 million people die from air pollution each year. Breathing polluted air increases the risk of developing lung diseases such as asthma and lung cancer. Breathing bad air also increases the chances of dying from other diseases. Children are most likely to be affected by air pollution. That’s because their lungs are still developing and growing. Children also take in more air for their size than adults do. Some air pollutants damage the environment as well as the health of living things. The type of damage depends on the pollutant. Air pollution can also harm the environment.  Paragraph: Tree city and Leaf city were the two biggest cities in Boulderland. Tree city burned lots of gas and other fossil fuels, while Leaf city was very protective towards its environment.  Given the paragraph above, please answer correctly the following question: Which city caused more harm to human beings?
A: Tree

Q: 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.  Paragraph: Dan and Fred were friends. they studied Biology at the same University. Fred studied bird reproduction this semester, while Dan studied fish reproduction.  Given the paragraph above, please answer correctly the following question: Which friend studied more about eggs that can be fertilized either inside or outside of the body?
A: Dan

Q: Background: No doubt you already have a good idea of what temperature is. You might say that it’s how warm or cool something feels. In physics, temperature is defined as the average kinetic energy of the particles of matter. When particles of matter move more quickly, they have more kinetic energy, so their temperature is higher. With a higher temperature, matter feels warmer. When particles move more slowly, they have less kinetic energy on average, so their temperature is lower. With a lower temperature, matter feels cooler.  Paragraph: Noah is currently making dinner in his kitchen. He has been boiling some soup on the stove for a while, so the temperature of the soup is currently high. Noah's brother, Justin, is sitting on the couch in the living room. Justin is eating ice cream, which has a low temperature.  Given the paragraph above, please answer correctly the following question: Are the particles moving slower in the ice cream or the soup?
A:
