     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 chronicles 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, dwarves, 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 denies the connection. He claims that the story began in his years as an undergraduate student 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 or work that is still read and enjoyed throughout the world today.

The following sentence could be added to paragraph 2. Where would it best fit into this paragraph?

“Once the ring is found by hobbit, a wizard selects a group to take the ring to the volcano where it was forged and destroy it.”

A. After the sentence that ends with “heroic epic”

B. After the sentence that ends with “fantasy world”

C. After the sentence that ends with “rule the world”

D. After the sentence that ends with “monster, wizards, and some humans”

Smart cards and mobile phones are becoming an increasingly popular way to make all sorts of payments. Even now, in Japan thousands of transactions, from paying rail tickets to picking up the groceries, take place every day with customers passing their handsets across a small flat-screen device. And predictions in the world of finance reckon that payments using mobile phones will have risen to more than $50 billion in the very near future.

What's the appeal of e-cash? Compared to cheques or credit cards, it offers the speed of cash, but more so. It takes just one tenth of a second to complete most transactions and as no change is required, errors in counting are eliminated. Fraud and theft are also reduced and for the retailer, it reduces the cost of handling money. Sony's vision of having a chip embedded in computers. TVs and games consoles means that films, music and games can be paid for easily and without having to input credit card details.

And what about the future of the banks? Within their grip on the market, banks and credit-card firms want to be in a position to collect most of the fees from the users of mobile and contactless-payment systems. But the new system could prove to be a "disruptive technology" as far as the banks are concerned. If payments for a few coffees, a train ticket and a newspaper are made every day by a commuter with a mobile, this will not appear on their monthly credit card statements but on their mobile phone statements. And having spent fortunes on branding, credit-card companies and banks do not want to see other payment systems gaining popularity. It's too early to say whether banks will miss out and if so, by how much. However, quite a few American bankers are optimistic They feel there is reason to he suspicious of those who predict that high-street banks may be a thing of the past. They point out that Internet banking did not result in the closure of their high-street branches as was predicted. On the contrary, more Americans than ever are using local branches. So, whether we'll become a totally cash-free society remains open to contention.

A. Daily expenses on drinks and tickets will appear on phone statements.

B. Banks will collect their fees through credit-card companies.
