Problem: Nutrition:

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.

What does soluble fiber do to help lower blood glucose levels?
---
A: slow the absorption of sugar


Problem: On runways, green lights indicate the beginning of the runway for landing, while red lights indicate the end of the runway. Runway edge lighting consists of white lights spaced out on both sides of the runway, indicating the edge. Some airports have more complicated lighting on the runways including lights that run down the centerline of the runway and lights that help indicate the approach (an approach lighting system, or ALS). Low-traffic airports may use pilot controlled lighting to save electricity and staffing costs.
On runways, what indicate the beginning of the runway for landing?

Answer: green lights

Confer With the White House. If his or her party controls the White House, the minority leader confers regularly with the President and his aides about issues before Congress, the Administration's agenda, and political events generally. Strategically, the role of the minority leader will vary depending on whether the President is of the same party or the other party. In general, minority leaders will often work to advance the goals and aspirations of their party's President in Congress. When Robert Michel, R-IL, was minority leader (1981–1995), he typically functioned as the "point man" for Republican presidents. President Ronald Reagan's 1981 policy successes in the Democratic controlled House was due in no small measure to Minority Leader Michel's effectiveness in wooing so-called "Reagan Democrats" to support, for instance, the Administration's landmark budget reconciliation bill. There are occasions, of course, when minority leaders will fault the legislative initiatives of their President. On an administration proposal that could adversely affect his district, Michel stated that he might "abdicate my leadership role [on this issue] since I can't harmonize my own views with the administration's." Minority Leader Gephardt, as another example, has publicly opposed a number of President Clinton's legislative initiatives from "fast track" trade authority to various budget issues.
What did Gephardt function as for Republican presidents?
A: unanswerable


Context and question: A gramophone record (phonograph record in American English) or vinyl record, commonly known as a "record", is an analogue sound storage medium in the form of a flat polyvinyl chloride (previously shellac) disc with an inscribed, modulated spiral groove. The groove usually starts near the periphery and ends near the center of the disc. Phonograph records are generally described by their diameter in inches (12", 10", 7"), the rotational speed in rpm at which they are played (16 2⁄3, 33 1⁄3, 45, 78), and their time capacity resulting from a combination of those parameters (LP – long playing 33 1⁄3 rpm, SP – 78 rpm single, EP – 12-inch single or extended play, 33 or 45 rpm); their reproductive quality or level of fidelity (high-fidelity, orthophonic, full-range, etc.), and the number of audio channels provided (mono, stereo, quad, etc.).
What is a gramophone or 'vinyl' record?
Answer: analogue sound storage medium


Question: After defeating the Visigoths in only a few months, the Umayyad Caliphate started expanding rapidly in the peninsula. Beginning in 711, the land that is now Portugal became part of the vast Umayyad Caliphate's empire of Damascus, which stretched from the Indus river in the Indian sub-continent (now Pakistan) up to the South of France, until its collapse in 750. That year the west of the empire gained its independence under Abd-ar-Rahman I with the establishment of the Emirate of Córdoba. After almost two centuries, the Emirate became the Caliphate of Córdoba in 929, until its dissolution a century later in 1031 into no less than 23 small kingdoms, called Taifa kingdoms.
Is there an answer to this question: In which year did Umayyad Caliphate's empire collapse?

Answer: 750

Game players were not the only ones to notice the violence in this game; US Senators Herb Kohl and Joe Lieberman convened a Congressional hearing on December 9, 1993 to investigate the marketing of violent video games to children.[e] While Nintendo took the high ground with moderate success, the hearings led to the creation of the Interactive Digital Software Association and the Entertainment Software Rating Board, and the inclusion of ratings on all video games. With these ratings in place, Nintendo decided its censorship policies were no longer needed.
How did game players affect Nintendo's policy?
A:
