Input: Consider Input: Passage: Dietary fiber is a carbohydrate that is incompletely absorbed in humans and in some animals. Like all carbohydrates, when it is metabolized it can produce four Calories (kilocalories) of energy per gram. However, in most circumstances it accounts for less than that because of its limited absorption and digestibility. Dietary fiber consists mainly of cellulose, a large carbohydrate polymer which is indigestible as humans do not have the required enzymes to disassemble it. There are two subcategories: soluble and insoluble fiber. Whole grains, fruits (especially plums, prunes, and figs), and vegetables are good sources of dietary fiber. There are many health benefits of a high-fiber diet. Dietary fiber helps reduce the chance of gastrointestinal problems such as constipation and diarrhea by increasing the weight and size of stool and softening it. Insoluble fiber, found in whole wheat flour, nuts and vegetables, especially stimulates peristalsis – the rhythmic muscular contractions of the intestines, which move digesta along the digestive tract. Soluble fiber, found in oats, peas, beans, and many fruits, dissolves in water in the intestinal tract to produce a gel that slows the movement of food through the intestines. This may help lower blood glucose levels because it can slow the absorption of sugar. Additionally, fiber, perhaps especially that from whole grains, is thought to possibly help lessen insulin spikes, and therefore reduce the risk of type 2 diabetes. The link between increased fiber consumption and a decreased risk of colorectal cancer is still uncertain. Question: What is the main component that makes up dietary fiber?

Output: cellulose


Input: Consider Input: Passage: Fryderyk's father, Nicolas Chopin, was a Frenchman from Lorraine who had emigrated to Poland in 1787 at the age of sixteen. Nicolas tutored children of the Polish aristocracy, and in 1806 married Justyna Krzyżanowska, a poor relative of the Skarbeks, one of the families for whom he worked. Fryderyk was baptized on Easter Sunday, 23 April 1810, in the same church where his parents had married, in Brochów. His eighteen-year-old godfather, for whom he was named, was Fryderyk Skarbek, a pupil of Nicolas Chopin. Fryderyk was the couple's second child and only son; he had an elder sister, Ludwika (1807–55), and two younger sisters, Izabela (1811–81) and Emilia (1812–27). Nicolas was devoted to his adopted homeland, and insisted on the use of the Polish language in the household. Question: What language did Frédéric's father, Nicolas, insist on using in the household?

Output: Polish


Input: Consider Input: Passage: The West Campus is located about one mile (1.6 km) to the west of the Danforth Campus in Clayton, Missouri, and primarily consists of a four-story former department store building housing mostly administrative space. The West Campus building was home to the Clayton branch of the Famous-Barr department store until 1990, when the University acquired the property and adjacent parking and began a series of renovations. Today, the basement level houses the West Campus Library, the University Archives, the Modern Graphic History Library, and conference space. The ground level still remains a retail space. The upper floors house consolidated capital gifts, portions of alumni and development, and information systems offices from across the Danforth and Medical School campuses. There is also a music rehearsal room on the second floor. The West Campus is also home to the Center for the Application of Information Technologies (CAIT), which provides IT training services. Question: Where is the West Campus of Washington University located?


Output: Clayton, Missouri
