input: Please answer the following: Background: The epidermis also contains melanocytes , which are cells that produce melanin. Melanin is the brownish pigment that gives skin much of its color. Everyone has about the same number of melanocytes, but the melanocytes of people with darker skin produce more melanin. The amount of melanin produced is determined by heredity and exposure to UV light, which increases melanin output. Exposure to UV light also stimulates the skin to produce vitamin D . Because melanin blocks UV light from penetrating the skin, people with darker skin may be at greater risk of vitamin D deficiency. Paragraph: John is learning more about different cultures and people around the world. He noticed that people have different skin colors. To learn more about the science behind skin colors he categorized the skin colors into two broad groups, case D and case L. Case D is represented by darker skin and case L is represented by lighter skin. Given the paragraph above, please answer correctly the following question: In which case melanocytes would produce less melanin, case D or case L?
++++++++++
output: case L

input: Please answer the following: Background: The strength of an acid refers to its ability or tendency to lose a proton. A strong acid is one that completely dissociates in water; in other words, one mole of a strong acid HA dissolves in water yielding one mole of H+ and one mole of the conjugate base, A, and none of the protonated acid HA. In contrast, a weak acid only partially dissociates and at equilibrium both the acid and the conjugate base are in solution. Examples of strong acids are hydrochloric acid (HCl), hydroiodic acid (HI), hydrobromic acid (HBr), perchloric acid (HClO4), nitric acid (HNO3) and sulfuric acid (H2SO4). In water each of these essentially ionizes 100%. The stronger an acid is, the more easily it loses a proton, H+. Two key factors that contribute to the ease of deprotonation are the polarity of the HA bond and the size of atom A, which determines the strength of the HA bond. Acid strengths are also often discussed in terms of the stability of the conjugate base. Paragraph: David is a chemical engineer. Yesterday, he was working on two samples, sample A and sample B. Sample A was a strong acid, and sample B was a weak acid. David needed to find the differences between them. Given the paragraph above, please answer correctly the following question: Which would lose a proton more easily, sample A or sample B?
++++++++++
output: sample A

input: Please answer the following: Background: Figure B above shows an important relationship between the wavelength and frequency of a wave. The top wave clearly has a shorter wavelength than the second wave. However, if you picture yourself at a stationary point watching these waves pass by, more waves of the first kind would pass by in a given amount of time. Thus the frequency of the first waves is greater than that of the second waves. Wavelength and frequency are therefore inversely related. As the wavelength of a wave increases, its frequency decreases. The equation that relates the two is Paragraph: Bill is working in a sound studio recording sound effects for a short film that he is working on. Some of the sounds he captured have a very high frequency and others are very low frequency. When he is done he begins to edit the sound with a computer program. Given the paragraph above, please answer correctly the following question: Do the high frequency sounds have a longer or shorter wavelength than the low frequency sounds?
++++++++++
output: shorter

input: Please answer the following: Background: Another example of incomplete dominance is with sickle cell anemia, a disease in which a blood protein called hemoglobin is produced incorrectly. This causes the red blood cells to have a sickle shape, making it difficult for these misshapen cells to pass through the smallest blood vessels. A person that is homozygous recessive ( ss ) for the sickle cell trait will have red blood cells that all have the incorrect hemoglobin. A person who is homozygous dominant ( SS ) will have normal red blood cells. Paragraph: Two sisters named Mary and Ann went in for a blood test and found out that Mary had sickle cell anemia. Ann was normal. Given the paragraph above, please answer correctly the following question: Which sister was homozygous recessive?
++++++++++
output:
Mary
