Input: Article: Mammalian hair, also known as pelage, can vary in color between populations, organisms within a population, and even on the individual organism. Light-dark color variation is common in the mammalian taxa. Sometimes, this color variation is determined by age variation, however, in other cases, it is determined by other factors. Selective pressures, such as ecological interactions with other populations or environmental conditions, often lead to the variation in mammalian coloration. These selective pressures favor certain colors in order to increase survival. Camouflage is thought to be a major selection pressure shaping coloration in mammals, although there is also evidence that sexual selection, communication, and physiological processes may influence the evolution of coloration as well. Camouflage is the most predominant mechanism for color variation, as it aids in the concealment of the organisms from predators or from their prey. Coat color can also be for intraspecies communication such as warning members of their species about predators, indicating health for reproductive purposes, communicating between mother and young, and intimidating predators. Studies have shown that in some cases, differences in female and male coat color could indicate information nutrition and hormone levels, which are important in the mate selection process. One final mechanism for coat color variation is physiological response purposes, such as temperature regulation in tropical or arctic environments. Although much has been observed about color variation, much of the genetic that link coat color to genes is still unknown. The genetic sites where pigmentation genes are found are known to affect phenotype by: 1) altering the spatial distribution of pigmentation of the hairs, and 2) altering the density and distribution of the hairs. Quantitative trait mapping is being used to better understand the distribution of loci responsible for pigmentation variation. However, although the genetic sites are known, there is still much to learn about how these genes are expressed.

Now answer this question: Which color of hair is most common among mammalian taxa?

Output: Light-dark color

Input: Article: There are many rules to contact in this type of football. First, the only player on the field who may be legally tackled is the player currently in possession of the football (the ball carrier). Second, a receiver, that is to say, an offensive player sent down the field to receive a pass, may not be interfered with (have his motion impeded, be blocked, etc.) unless he is within one yard of the line of scrimmage (instead of 5 yards (4.6 m) in American football). Any player may block another player's passage, so long as he does not hold or trip the player he intends to block. The kicker may not be contacted after the kick but before his kicking leg returns to the ground (this rule is not enforced upon a player who has blocked a kick), and the quarterback, having already thrown the ball, may not be hit or tackled.

Now answer this question: Within what distance from the line of scrimmage can offensive players who do not have the ball be legally contacted by defensive players?

Output: one yard

Input: Article: The Somerset Levels (or Somerset Levels and Moors as they are less commonly but more correctly known) are a sparsely populated wetland area of central Somerset, between the Quantock and Mendip hills. They consist of marine clay levels along the coast, and the inland (often peat based) moors. The Levels are divided into two by the Polden Hills; land to the south is drained by the River Parrett while land to the north is drained by the River Axe and the River Brue. The total area of the Levels amounts to about 647.5 square kilometres (160,000 acres) and broadly corresponds to the administrative district of Sedgemoor but also includes the south west of Mendip district. Approximately 70% of the area is grassland and 30% is arable. Stretching about 32 kilometres (20 mi) inland, this expanse of flat land barely rises above sea level. Before it was drained, much of the land was under a shallow brackish sea in winter and was marsh land in summer. Drainage began with the Romans, and was restarted at various times: by the Anglo-Saxons; in the Middle Ages by the Glastonbury Abbey, from 1400–1770; and during the Second World War, with the construction of the Huntspill River. Pumping and management of water levels still continues.

Now answer this question: what do the Somerset levels consist of 

Output:
marine clay levels along the coast, and the inland (often peat based) moors
