Please answer this: Background: Carbon monoxide is used in modified atmosphere packaging systems in the US, mainly with fresh meat products such as beef, pork, and fish to keep them looking fresh. The carbon monoxide combines with myoglobin to form carboxymyoglobin, a bright-cherry-red pigment. Carboxymyoglobin is more stable than the oxygenated form of myoglobin, oxymyoglobin, which can become oxidized to the brown pigment metmyoglobin. This stable red color can persist much longer than in normally packaged meat. Typical levels of carbon monoxide used in the facilities that use this process are between 0.4% to 0.5%. Paragraph: Anna is going grocery shopping today. She gets to the meat section and decides to buy some ground beef. While looking at the cases she notices 2 brands of meat, Brand A and brand B. Bother were packaged the same day but package B's meat is noticeably more brown in color. Given the paragraph above, please answer correctly the following question: Will the red pigment of meat last longer or shorter if it is treated with carbon monoxide?
++++++++
Answer: longer

Problem: Background: 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. Paragraph: 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 start taking statins for his disease?

A: Andy

Problem: Given the question: Background: An anaerobic organism is any organism that does not need oxygen for growth and even dies in its presence. Obligate anaerobes will die when exposed to atmospheric levels of oxygen. Clostridium perfringens bacteria, which are commonly found in soil around the world, are obligate anaerobes. Infection of a wound by C. perfringens bacteria causes the disease gas gangrene. Obligate anaerobes use molecules other than oxygen as terminal electron acceptors. Paragraph: Microbiologist John is studying the anaerobic organism. He collected two samples of this organism, sample A and sample B. Sample A is an anaerobic organism, and sample B is specifically identified as the Clostridium perfringens obligate anaerobe. To compare these samples to other organisms he collected another microbe that is not an anaerobic organism. He labeled it as sample C. Given the paragraph above, please answer correctly the following question: Which sample would not use oxygen as terminal electron acceptor, sample A or sample C?
++++++++++++++++++++++++++++++++
The answer is:
sample A

input question: Background: Old age begins in the mid-60s and lasts until the end of life. Most 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: Doctors studied two groups of individuals: group O with people over 65, and group S with people under 65 years old. They published the results in a magazine. Given the paragraph above, please answer correctly the following question: Which group had fewer people with decreased stamina????
output answer: group S

Background: With shade applications, crops are purposely raised under tree canopies within the shady environment. The understory crops are shade tolerant or the overstory trees have fairly open canopies. A conspicuous example is shade-grown coffee. This practice reduces weeding costs and improves coffee quality and taste. The shade does not necessarily translate into lost or reduced yields. This is because the rate of photosynthesis hardly increases once the light intensity is over about one tenth that of direct overhead sunlight and declines with increasing light intensity. This means that shaded plants can grow well. Planting more than one level of vegetation can increase total photosynthesis and overall yields. Paragraph: Two coffee farms used different methods to grow coffee. Hill farm grown coffee conventionally, while Valley farm is into shade-grown coffee production. Given the paragraph above, please answer correctly the following question: Which farm grew less coffee with improved quality?
----
Answer: Hill

Q: Background: Using longitudinal data from over 100 countries, Diener and his colleagues showed that rich countries are in general happier than poor countries (Diener, Tay, & Oishi, 2013).[17] Also, life satisfaction for most countries goes up as they become wealthier over time. Diener identified three factors that influence the relationship between income and SWB. Namely, rising income most likely results in higher SWB when it leads to greater optimism, financial satisfaction and household material prosperity among citizens. Furthermore, Diener and his colleagues investigated the relationship between income and different elements of SWB. They illustrated that income has stronger influence on people's evaluation of their lives than the positive or negative emotions they experience over time (Diener, Kahneman, Tov, & Arora, 2010).[18] The study points to the necessity to evaluate different elements of SWB separately instead of treating happiness as a single entity. Paragraph: Over the years, the town of Euphoria has grown more successful and wealthier than anyone ever thought. As the wealth has increased and people have acquired more material possessions, their outlook on life has become more positive and it has been noted that the citizens have a lower incidence of depression. The town of Zenphora, on the other hand, has taken a downward financial turn over the past 50 years. The citizens have had to sell their worldly goods just to make ends meet and many do not have a good feeling about what their future holds. Given the paragraph above, please answer correctly the following question: Do the people of Zenphora have more life satisfaction or less life satisfaction?
A:
less
