Problem: Given the question: Mike is an an archeologist. He was pondering about how human legacy would be viewed in the future. For that, he was very interested in technofossils. He located a site with ample evidence of technofossils. He noted that site as site A. To compare site A with a site with no technofossils he located another site. He noted that site as site B. Given the paragraph above, please answer correctly the following question: Which site would see more litter and debris deposited, site A or site B? Hint: Increases in erosion due to farming and other operations will be reflected by changes in sediment composition and increases in deposition rates elsewhere. In land areas with a depositional regime, engineered structures will tend to be buried and preserved, along with litter and debris. Litter and debris thrown from boats or carried by rivers and creeks will accumulate in the marine environment, particularly in coastal areas. Such manmade artifacts preserved in stratigraphy are known as "technofossils."Changes in biodiversity will also be reflected in the fossil record, as will species introductions. An example cited is the domestic chicken, originally the red junglefowl Gallus gallus, native to south-east Asia but has since become the world's most common bird through human breeding and consumption, with over 60 billion consumed a year and whose bones would become fossilized in landfill sites. Hence, landfills are important resources to find "technofossils".

The answer is:
site A

Problem: Given the question: Ben and Andy were two old friends. They both have high levels of cholesterol. Ben was prescribed cholesterol medication, while Andy didn't go to the doctor because he was careless. Given the paragraph above, please answer correctly the following question: Which friend didn't take a drug that changed the levels of HMG-CoA reductase? Hint: Currently, millions of individuals with high cholesterol take a similar type of drug, known as a statin. The drug, an inhibitor of HMG-CoA reductase (3-hydroxy-3-methyl-glutaryl-CoA reductase), the rate limiting enzyme in cholesterol biosynthesis, decreases blood levels of cholesterol by induce the expression of low density lipoprotein (LDL) receptors in the liver. The increased levels of the LDL-receptors stimulate the catabolism of plasma LDL, removing cholesterol from plasma, which is an important determinant of atherosclerosis. You may know of people who take a statin to help with their cholesterol levels. However, these drugs probably work slightly differently in many of those people. In some, it lowers their cholesterol significantly; in others it may lower it only moderately; and in some, it may have no significant effect at all. (Luckily for those individuals, there are multiple versions of the statins, so different drugs can be tested to find the proper combination for that individual.) Why the difference? Because of the genetic background of all people; the different single nucleotide polymorphisms that make us all different. Pharmacogenomics, a combination of pharmacology and genomics (the study of the genome) that refers to the study of the relationship between pharmaceuticals and genetics, may explain and simplify this problem.

Problem: Given the question: Bend village was located 20 miles away from Mound village. People in Bend village used gasoline powered vehicles, while Mound village used only electrical vehicles. Given the paragraph above, please answer correctly the following question: Which village emitted more carbon monoxide? Hint: Gasoline-powered vehicles emit a lot of harmful materials. Nitrogen oxides are formed when atmospheric nitrogen reacts with oxygen at the high temperatures found in a car engine. Carbon monoxide is a by-product of incomplete combustion of hydrocarbons. Evaporated and unused fuel releases volatile hydrocarbons into the atmosphere to help form smog. The presence of a catalytic converter in the exhaust system of the car causes these materials to react and be changed into less harmful products.
