Answer the following question given this paragraph: Over 2500 years ago Aristotle proposed two laws of physics governing motion. One for 'Earthly bodies' (objects on Earth) that states objects naturally go in straight lines and one for 'Heavenly bodies' (objects in space) that states objects naturally go in circles. This idea held steady for 2,000 years until Isaac Newton, in a triumph of brilliance, declared that there is one law of physics that governs motion and he unified "earthly" bodies and "heavenly" bodies with the The Universal Law of Gravitation. Newton used the universal law of gravity to prove that the moon is accelerating towards Earth just as a body on Earth is falling towards it. The acceleration of both the moon and the object on Earth is calculated using the same formula. This theory is so well regarded that it has been used to hypothesize the existence of black holes and dark matter, later verified by observation. The search to unify the laws of physics into one theory continues today and is often referred to as the yet undiscovered Grand Unified Theory (GUT). Q: The as yet undiscovered grand unified theory is a search to unify laws of what branch of science? A:

OPTIONS:
- genetics
- chemistry
- masses
- physics

Answer: physics

Problem: OPTIONS:
- hands
- lungs

- kidneys
Q: Answer the following question given this paragraph: 25.3 Gross Anatomy of the Kidney As noted previously, the structure of the kidney is divided into two principle regionsthe peripheral rim of cortex and the central medulla. The two kidneys receive about 25 percent of cardiac output. They are protected in the retroperitoneal space by the renal fat pad and overlying ribs and muscle. Ureters, blood vessels, lymph vessels, and nerves enter and leave at the renal hilum. The renal arteries arise directly from the aorta, and the renal veins drain directly into the inferior vena cava. Kidney function is derived from the actions of about 1.3 million nephrons per kidney; these are the "functional units. " A capillary bed, the glomerulus, filters blood and the filtrate is captured by Bowman's capsule. A portal system is formed when the blood flows through a second capillary bed surrounding the proximal and distal convoluted tubules and the loop of Henle. Most water and solutes are recovered by this second capillary bed. This filtrate is processed and finally gathered by collecting ducts that drain into the minor calyces, which merge to form major calyces; the filtrate then proceeds to the renal pelvis and finally the ureters. Q: What paired organs together receive about 25 percent of cardiac output and are protected in the retroperitoneal space by the renal fat pad and overlying ribs and muscle? A:
Answer: kidneys

Answer the following question given this paragraph: Sulfur enters the ocean in runoff from land, from atmospheric fallout, and from underwater geothermal vents. Some ecosystems rely on chemoautotrophs using sulfur as a biological energy source. This sulfur then supports marine ecosystems in the form of sulfates. Human activities have played a major role in altering the balance of the global sulfur cycle. The burning of large quantities of fossil fuels, especially from coal, releases larger amounts of hydrogen sulfide gas into the atmosphere. As rain falls through this gas, it creates the phenomenon known as acid rain, which damages the natural environment by lowering the pH of lakes, thus killing many of the resident plants and animals. Acid rain is corrosive rain caused by rainwater falling to the ground through sulfur dioxide gas, turning it into weak sulfuric acid, which causes damage to aquatic ecosystems. Acid rain also affects the man-made environment through the chemical degradation of buildings. For example, many marble monuments, such as the Lincoln Memorial in Washington, DC, have suffered significant damage from acid rain over the years. These examples show the wide-ranging effects of human activities on our environment and the challenges that remain for our future. Q: Acid rain is corrosive rain caused by rainwater falling to the ground through which gas? A:
OPTIONS:
- sulfide dioxide
- carbon dioxide
- essential dioxide
- sulfur dioxide

Answer: sulfur dioxide

input with options: Answer the following question given this paragraph: The brain is a marvelous organ. And it's a hungry one, too. The major fuel for the brain is the carbohydrate glucose. The average adult brain represents about 2% of our body's weight, but uses 25% of the glucose in the body. Moreover, specific areas of the brain use glucose at different rates. If you are concentrating hard, (taking a test, for example) certain parts of the brain need a lot of extra glucose while other parts of the brain only use their normal amount. Something to think about. Q: The major fuel for the brain is which carbohydrate? A:
OPTIONS:
- glutamate
- sucrose
- insulin
- glucose
output:
glucose
