input question: A pharmaceutical company is trying to find the cure for allergy. To that end, they conducted an experiment with two groups of subjects, group A and group B. They exposed the participants in group A to allergen, but they didn't expose the participants in group B to any allergen. The symptoms of these two groups would help them find the cure for allergy. Which group's subjects would most likely start coughing, group A or group B? Hint: An allergy is a disease in which the immune system makes an inflammatory response to a harmless antigen . Any antigen that causes an allergy is called an allergen. Allergens may be inhaled or ingested, or they may come into contact with the skin. Two common causes of allergies are shown in Figure below . Inhaling ragweed pollen may cause coughing and sneezing. Skin contact with oils in poison ivy may cause an itchy rash. Other common causes of allergies include dust mites, mold, animal dander, insect stings, latex, and certain food and medications. Symptoms of a common allergy such as pollen can include sneezing, a runny nose, nasal congestion and itchy, watery eyes.???
output answer: group A

Air pollution is a big problem in large industrial cities. New York has its share or air pollution. John is a doctor who works for a New York hospital. Today, he is seeing two patients, patient A and patient B. His diagnosis revealed that patient A has pulmonary fibrosis, but patient B does not have pulmonary fibrosis. In which patient John found thickening of lung walls, patient A or patient B? Hint: Pulmonary fibrosis (literally "scarring of the lungs") is a respiratory disease in which scars are formed in the lung tissues, leading to serious breathing problems. Scar formation, the accumulation of excess fibrous connective tissue (the process called fibrosis), leads to thickening of the walls, and causes reduced oxygen supply in the blood. As a consequence patients suffer from perpetual shortness of breath.[1]

Q: Greg is a doctor with the city hospital. Today, he is seeing two patients, patient A and patient B. Patient A maintains a high-fat diet, but patient B does not maintain a high fat diet. Greg is advising the patients how lifestyle change can improve their health. Would patient B have more or less lipid in the blood than patient A? Hint: Although some lipids in the diet are essential, excess dietary lipids can be harmful. Because lipids are very high in energy, eating too many may lead to unhealthy weight gain. A high-fat diet may also increase lipid levels in the blood. This, in turn, can increase the risk for health problems such as cardiovascular disease. The dietary lipids of most concern are saturated fatty acids, trans fats, and cholesterol. For example, cholesterol is the lipid mainly responsible for narrowing arteries and causing the disease atherosclerosis.
A: less

Question: In central Ireland there are two farms next to two very similar lakes, and both farms use the same fertilizer to grow crops. The farm next to lake Montopeke gets rain on a regular basis and so the farmer doesn't need to water his crops as much. The farm that is adjacent to lake Costanza hardly gets any rain at all though. Both farms are able to prosper and do well though despite the different amount of rain they get. Does lake Montopeke have more or less oxygen than lake Costanza? Hint: Rain dissolves fertilizer in the soil. Runoff carries it away. The fertilizer ends up in bodies of water, from ponds to oceans. Nitrogen is a fertilizer in the water. Since there is a lot of nitrogen, it causes algae to grow out of control. Pictured below is a pond covered with algae ( Figure below ). Algae use up carbon dioxide in the water. After the algae die, decomposers break down the dead tissue. The decomposers use up all the oxygen in the water. This creates a dead zone. A dead zone is an area in a body of water where nothing grows because there is too little oxygen. There is a large dead zone in the Gulf of Mexico ( Figure below ). The U.S. states outlined on the map have rivers that drain into the Gulf of Mexico. The rivers drain vast agricultural lands. The water carries fertilizer from these areas into the Gulf.
Answer: less

[Q]: Two teams of researchers studied the environment in Antarctica. Team Black studied air pollution and the ozone layer, Team Red studied the water. Which team observed that aerosol sprays are being released into the atmosphere? Hint: Unfortunately, the layer of good ozone is being destroyed by air pollution. The chief culprits are chlorine and bromine gases. They are released in aerosol sprays, coolants, and other products. Loss of ozone has created an ozone hole over Antarctica. Ozone depletion results in higher levels of UV radiation reaching Earth. In humans, this increases skin cancers and eye cataracts. It also disturbs the nitrogen cycle, kills plankton, and disrupts ocean food webs. The total loss of the ozone layer would be devastating to most life. Its rate of loss has slowed with restrictions on pollutants, but it is still at risk.

Problem: Given the question: Two sailors, Jim and Eric decide to buy boats. The boats they buy ave a decent amount of iron in the construction and will be exposed to water almost constantly. Jim decides to coat his boat in a protective seal that seals out water and air. Eric thinks this is unnecessary and does not buy the protective seal. Will the boat that Jim bought or the boat that Eric bought corrode faster? Hint: Iron is first oxidized to iron(II) ions by oxygen. In the second step, the iron(II) ions are further oxidized and combine with water and oxygen gas to produce a hydrated form of iron(III) oxide known as rust. Rusting is one of many example of corrosion. Corrosion is the deterioration of metals by redox processes. Corrosion causes enormous amounts of damage to buildings, bridges, ships, cars, and other objects. It has been estimated that corrosion costs the U.S. economy over 100 billion dollars each year. A great amount of time and effort is spent to try to limit or prevent corrosion.
