Vitamins, taken in tiny doses, are a major group of organic compounds that regulate the mechanisms by which the body converts food into energy. They should not be confused with minerals, which are inorganic in their makeup. Although in general the naming of vitamins followed the alphabetical order of their identification, the nomenclature of individual substances may appear to be somewhat random and disorganized. Among the 13 vitamins known today, five are produced in the body. Because the body produces sufficient quantities of some but not all vitamins, they must be supplemented in the daily diet. Although each vitamin has its specific designation and cannot be replaced by another compound, a lack of one vitamin can interfere with the processing of another. When a lack of even one vitamin in a diet is continual, a vitamin deficiency may result.

The locations of stars in the sky relative to one another do not appear to the naked eye to change, and as a result stars are often considered to be fixed in position. Many unaware stargazers falsely assume that each star has its own permanent home in the nighttime sky.

In reality, though, stars are always moving, but because of the tremendous distances between stars themselves and from stars to Earth, the changes are barely perceptible here. An example of a rather fast-moving star demonstrates why this misconception prevails; it takes approximately 200 years for a relatively rapid star like Bernard's star to move a distance in the skies equal to the diameter of the earth's moon. When the apparently negligible movement of the stars is contrasted with the movement of the planets, the stars are seemingly unmoving.

While the bald eagle is one national symbol of the United States, it is not the only one. Uncle Sam, a bearded gentleman costumed in the red, white, and blue stars and stripes of the nation's flag, is another well-known national symbol. According to legend, this character is based on Samuel Wilson, the owner of a meat-packing business in Troy, New York. During the War of 1812, Sam Wilson's company was granted a government contract to supply meat to the nation's soldiers; this meat was supplied to the army in barrels stamped with the initials U.S., which stood for United States. However, the country was at that time relatively young, and the initials U.S. were not commonly used. Many people questioned what the initials represented, and the standard reply became "Uncle Sam," for the owner of the barrels. It is now generally accepted that the figure of Uncle Sam is based on Samuel Wilson, and the U.S. Congress has made it official by adopting a resolution naming Samuel Wilson as the inspiration for Uncle Sam.

According to the passage, what was in the barrels stamped U.S.?

The railroad was not the first institution to impose regularity on society, or to draw attention to the importance of precise timekeeping. For as long as merchants have set out their wares at daybreak and communal festivities have been celebrated, people have been in rough agreement with their neighbors as to the time of day. The value of this tradition is today more apparent than ever. Were it not for public acceptance of a single yardstick of time, social life would be unbearably chaotic: the massive daily transfers of goods, services, and information would proceed in fits and starts; the very fabric of modern society would begin to unravel.

In line 7, the phrase "this tradition" refers to

Economic contact between Native Americans and Europeans can be traced back to the English and French fishermen off the coast of Canada in the 1500s. They traded guns and other weapons for beaver fur. The first explorers to trade with the Native Americans were Giovanni da Verrazano and Jacques Cartier in the 1520s and 1530s. In Verrazano's book he notes, "If we wanted to trade with them for some of their things, they would come to the seashore on some rocks where the breakers were most violent while we remained on the little boat, and they sent us what they wanted to give on a rope, continually shouting to us not to approach the land."

The word 'They' in paragraph 3 refers to?
