input: Please answer the following: Background: The lungs of mammals are unique in having alveoli . These are tiny, sac-like structures. Each alveolus is surrounded by a network of very small blood vessels (see Figure below ). Because there are millions of alveoli in each lung, they greatly increase the surface area for gas exchange between the lungs and bloodstream. Human lungs, for example, contain about 300 million alveoli. They give the lungs a total surface area for gas exchange of up to 90 square meters (968 square feet). That's about as much surface area as one side of a volleyball court! Paragraph: Two groups of students studied Biology. Group One studied mammals, while Group Two studied birds. They focused on the respiratory system. Given the paragraph above, please answer correctly the following question: Which group of students learned more about the surface area for gas exchange between the lungs and bloodstream?
++++++++++
output: One

Please answer this: Background: Hepatitis B is a contagious virus that affects the liver, infection can last from a few weeks to a serious lifelong illness. Two different types of infection exist for this disease, "acute" and "chronic." Acute Hepatitis B is a short term illness that occurs within 6 months of exposure, Chronic Hepatitis B is long term and happens when the virus remains in the body. The younger the child is, the greater their chance of developing a chronic infection and this risk goes down as the child gets older. Approximately 90% of infected infants will develop a chronic infection.[3] Paragraph: Bob has just graduated from medical school. He went on to serve his community. Especially he is interested in treating children. One day he saw two children, child M and child N, and found child M is infected with Acute Hepatitis B while child N is infected with Chronic Hepatitis B. Next day he saw two other children, child O and child P. Child O was younger, but child P was older. Given the paragraph above, please answer correctly the following question: Which child had long term illness, child M or child N?
++++++++
Answer: child N

Problem: Background: Alpine tundra occurs at high enough altitude at any latitude. Portions of montane grasslands and shrublands ecoregions worldwide include alpine tundra. Large regions of alpine tundra occur in the North American Cordillera, the Alps and Pyrenees of Europe, the Himalaya and Karakoram of Asia, the Andes of South America, and the Eastern Rift mountains of Africa.Alpine tundra occupies high-mountain summits, slopes, and ridges above timberline. Aspect plays a role as well; the treeline often occurs at higher elevations on warmer equator-facing slopes. Because the alpine zone is present only on mountains, much of the landscape is rugged and broken, with rocky, snowcapped peaks, cliffs, and talus slopes, but also contains areas of gently rolling to almost flat topography.Averaging over many locations and local microclimates, the treeline rises 75 metres (245 ft) when moving 1 degree south from 70 to 50N, and 130 metres (430 ft) per degree from 50 to 30N. Between 30N and 20S, the treeline is roughly constant, between 3,500 and 4,000 metres (11,500 and 13,100 ft). Paragraph: Redland and Brownland were two countries situated at different latitudes. Redland was located at 70 degrees N, while Brownland was much further south, at 30 degrees N. Brownland had no mountains, only a few hills under 1000 ft. Given the paragraph above, please answer correctly the following question: Which country had more montane grasslands?

A: Redland

Problem: Given the question: Background: A After a rock forms, nuclei of a radioisotope inside the rock start to decay. As they decay, the amount of the original, or parent, isotope decreases, while the amount of its stable decay product, or daughter isotope, increases. By measuring the relative amounts of parent and daughter isotopes and knowing the rate of decay, scientists can determine how long the parent isotope has been decaying. This provides an estimate of the rock's age. Paragraph: Gregory is a geologist who went on an excursion to Australia. While hiking in a cave, Gregory found two radioactive rocks containing Uranium. Gregory then brought the rocks back to his lab in Germany to conduct tests. Gregory discovered that rock A had high amounts of the original uranium isotope present, and low amounts of the daughter uranium isotope present. In rock B, however, there were low amounts of the original uranium isotope present and high amounts of the daughter uranium isotope present. Given the paragraph above, please answer correctly the following question: Which rock, rock A or rock B, had been decaying over a shorter period of time?
++++++++++++++++++++++++++++++++
The answer is:
rock A

input question: Background: Air pollution can also indirectly cause other health issues and even deaths. Air pollutants can cause an increase in cancer including lung cancer, eye problems, and other conditions. For example, using certain chemicals on farms, such as the insecticide DDT (dichlorodiphenyltrichloroethane) and toxic PCBs (polychlorinated biphenyl), can cause cancer. Indoors, pollutants such as radon or asbestos can also increase your cancer risk. Lastly, air pollution can lead to heart disease, including heart attack and stroke. Paragraph: Two neighboring towns had different methods of growing crops. Lean town used insecticides, while Bean town did not. Lean town had high levels of air pollution. Given the paragraph above, please answer correctly the following question: Which town had more inhabitants experiencing cancer????
output answer: Lean

input question: Background: However, when going across a period from left to right, the atomic radius actually tends to decrease. Why is this so? Each successive electron is going into the same principal energy level as the previous one, so the total amount of occupied space does not really go up significantly. Additionally, because protons are also added to the nucleus as you go across the row, the pull of the positively charged nucleus on the negatively charged electrons increases. This tighter pull leads to a slight decrease in atomic radius. As a result, the atomic radii of the elements exhibit a periodic trend, gradually tends to downward, but with a sharp spike up whenever electrons are added to a new principal energy level ( Figure below ). Paragraph: There are two elements, Zaxon and Barton. Zaxon is an element that is further left on the period, and Barton is on the right of the period. Given the paragraph above, please answer correctly the following question: Which element will have a larger atomic radius????
output answer:
Zaxon
