Problem: Given the following passage  "In 2010, the literacy rate of Liberia was estimated at 60.8% (64.8% for males and 56.8% for females). In some areas primary and secondary education is free and compulsory from the ages of 6 to 16, though enforcement of attendance is lax. In other areas children are required to pay a tuition fee to attend school. On average, children attain 10 years of education (11 for boys and 8 for girls). The country's education sector is hampered by inadequate schools and supplies, as well as a lack of qualified teachers.",  answer the following question. Note that the answer is present within the text.  Question: How was the reading and writing ratio differentials between boys and girls determined in Liberia?

A: estimated


Problem: Given the following passage  "Richard Phillips Feynman (/ˈfaɪnmən/; May 11, 1918 – February 15, 1988) was an American theoretical physicist known for his work in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics, and the physics of the superfluidity of supercooled liquid helium, as well as in particle physics for which he proposed the parton model. For his contributions to the development of quantum electrodynamics, Feynman, jointly with Julian Schwinger and Sin-Itiro Tomonaga, received the Nobel Prize in Physics in 1965. He developed a widely used pictorial representation scheme for the mathematical expressions governing the behavior of subatomic particles, which later became known as Feynman diagrams. During his lifetime, Feynman became one of the best-known scientists in the world. In a 1999 poll of 130 leading physicists worldwide by the British journal Physics World he was ranked as one of the ten greatest physicists of all time.",  answer the following question. Note that the answer is present within the text.  Question: What did Feynman do when it came to quantum physics?

A: his work in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics


Problem: Given the following passage  "Apple's Safari had its first beta release in January 2003; as of April 2011, it had a dominant share of Apple-based web browsing, accounting for just over 7% of the entire browser market.",  answer the following question. Note that the answer is present within the text.  Question: By 12th year of the century known as the 2000s, what were Safari's numbers like?

A: accounting for just over 7% of the entire browser market


Problem: Given the following passage  "Lactase is an enzyme that breaks down the disaccharide lactose to its component parts, glucose and galactose. Glucose and galactose can be absorbed by the small intestine. Approximately 65 percent of the adult population produce only small amounts of lactase and are unable to eat unfermented milk-based foods. This is commonly known as lactose intolerance. Lactose intolerance varies widely by ethnic heritage; more than 90 percent of peoples of east Asian descent are lactose intolerant, in contrast to about 5 percent of people of northern European descent.",  answer the following question. Note that the answer is present within the text.  Question: What protein molecule can some people have trouble eating?

A:
Lactose
