Q: Background: Carbon dioxide is the most significant long-lived greenhouse gas in Earth's atmosphere. Since the Industrial Revolution anthropogenic emissions primarily from use of fossil fuels and deforestation have rapidly increased its concentration in the atmosphere, leading to global warming. Carbon dioxide also causes ocean acidification because it dissolves in water to form carbonic acid. Paragraph: Two counties were part of the same region. Green county used alternative methods to produce energy, while Brown county used fossil fuels and released a lot of carbon dioxide into the atmosphere. Given the paragraph above, please answer correctly the following question: Which county caused less global warming?
A: Green

Q: Background: Old age begins in the mid-60s and lasts until the end of life. Many people over 65 have retired from work, freeing up their time for hobbies, grandchildren, and other interests. Stamina, strength, reflex time, and the senses all decline during old age, and the number of brain cells decreases as well. The immune system becomes less efficient, increasing the risk of serious illnesses such as cancer and pneumonia. Diseases such as Alzheimer's disease that cause loss of mental function also become more common. Paragraph: Mark has just graduated high school and is going to visit his grandpa, Tom, over the summer for a couple days. Since Tom is retired, he often has plenty of time to go fishing, and he even has a small cabin by the lake. The two men are planning to spend several days at the cabin cooking, fishing, chopping firewood to make fires and just general outdoor activities. Given the paragraph above, please answer correctly the following question: Is Tom's chance of getting sick while at the cabin higher or lower than Mark's?
A: higher

Q: Background: The Hubble space telescope shows that technology and science are closely related. Technology uses science to solve problems, and science uses technology to make new discoveries. However, technology and science have different goals. The goal of science is to answer questions and increase knowledge. The goal of technology is to find solutions to practical problems. Although they have different goals, science and technology work hand in hand, and each helps the other advance. Scientific knowledge is used to create new technologies such as the space telescope. New technologies often allow scientists to explore nature in new ways. Paragraph: Stan Lawson is a biologist who studies marine life and has been keeping hand written notes for many years on experiments that he has performed. Jack Smith is an inventor and engineer who wants to create a new type of plastic companies can use that won't harm the ocean. They are considering joining together to work on this new venture. Given the paragraph above, please answer correctly the following question: Which person would provide the technological knowledge used to create the new product, Stan Lawson or Jack Smith?
A: Jack Smith

Q: Background: For example, if a solid pellet of NaOH is placed into a chamber of HCl gas, a relatively slow acid-base reaction will occur between gaseous HCl molecules and hydroxide ions on the surface of the pellet. If we were to grind the pellet into smaller pieces, it would greatly increase the total surface area, and therefore the overall reaction rate. Once ground up, many hydroxide ions that were on the interior of the pellet, where they were not exposed to any HCl molecules, will now be on the surface, where the necessary collisions can occur. Paragraph: In his chemistry lab David is experimenting with how NaOH and HCl gas reacts with each other. He conducted two experiments, experiment A and experiment B. In experiment A he used solid pellets of NaOH, but in experiment B he used ground NaOH. He was surprised to see the difference it made in his experiment. Given the paragraph above, please answer correctly the following question: Would experiment A's hydroxide have smaller or larger surface area than experiment B's hydroxide?
A:
smaller
