One of the most interesting authors of the twentieth century, J.R.R Tolkien, achieved fame through his highly inventive trilogy, The Lord of the Rings. Born in 1892, Tolkien received his education from Oxford and then served in World War I. After the war, he became a professor of Anglo -Saxon and English language and literature at Oxford University.

Although published in 1965, the three books that comprise the Lord of the Rings were written in intervals from 1936 to 1949. This was mainly due to Tolkien’s responsibilities as a professor and the outbreak of World War II. By the late 1960s, this fascinating trilogy had become a sociological phenomenon as young people intently studied the mythology and legends created by Tolkien.

The trilogy is remarkable not only for its highly developed account of historical fiction but also its success as a modern heroic epic. The main plot describes the struggle between good and evil kingdom as they try to acquire a magic ring that has the power to rule the world. The novels, which are set in a time called Middle Earth, describe a detailed fantasy world. Established before humans populated the Earth, Middle Earth was inhabited by good and evil creatures such as hobbits, elves, monsters, wizards, and some humans. The characters and the setting of Middle Earth were modeled after mythological stories from Greece and Northern Europe.

Although readers have scrutinized the texts for inner meaning and have tried to connect the trilogy with Tolkien’s real life experiences in England during World War II, he denied the connection. He claims that the story began in his years as an undergraduate student and grew out of his desire to create mythology and legends about elves and their language.

Tolkien was a masterful fantasy novelist who used his extensive knowledge of folklore to create a body of work that is still read and enjoyed throughout the world today

     Many ants forage across the countryside in large numbers and undertake mass migrations; these activities proceed because one ant lays a trail on the ground for the others to follow. As a worker ant returns home after finding a source of food, it marks the route by intermittently touching its stinger to the ground and depositing a tiny amount of trail pheromone – a mixture of chemicals that delivers diverse messages as the context changes. These trails incorporate no directional information and may be followed by other ants in either direction. 

     Unlike some other messages, such as the one arising from a dead ant, a food trail has to be kept secret from members of other species. It is not surprising then that ant species use a wide variety of compounds as trail pheromones. Ants can be extremely sensitive to these signals. Investigators working with the trail pheromone of the leafcutter ant Atta Texana calculated that one milligram of this substance would suffice to lead a column of ants three times around Earth. 

          The vapor of the evaporating pheromone over the trail guides an ant along the way, and the ant detects this signal with receptors in its antennae. A trail pheromone will evaporate to furnish the highest concentration of vapor right over the trail, in what is called a vapor space.  In following the trail, the ant moves to the right and left, oscillating from side to side across the line of the trail itself, bringing first one and then the other antenna into the vapor space. As the ant moves to the right, its left antenna arrives in the vapor space. The signal it receives causes it to swing to the left, and the ant then pursues this new course until its right antenna reaches the vapor space. It then swings back to the right, and so weaves back and forth down the trail

According to the passage, the highest amount of pheromone vapor is found _____
