A
Barcodes may seem common enough today that it`s tough to imagine a shopping trip without them. However, barcodes were actually not of much importance until the 1970's. The first product to be barcoded and scanned with the first barcode scanner ever used was in 1974. The idea of barcodes, on the other hand, is not quite as recent. In 1932, Wallace Flint claimed that it might be feasible to create an automated retail checkout system. Even though his idea was ruled out as a possibility in his time, Flint maintained his support for the creation of automated checkouts throughout his working life. It was Flint himself who ended up being a key player in developing UPC code, and went on to become the vice-president of the association of food chains about 40 years later.

答案：how the idea was eventually put into practice
原文定位：In 1932, Wallace Flint claimed that it might be feasible to create an automated retail checkout system. Even though his idea was ruled out as a possibility in his time;It was Flint himself who ended up being a key player in developing UPC code;The first product to be barcoded and scanned with the first barcode scanner ever used was in 1974
答案：addressing the need for an effective way to create an automated scanning system
原文定位：Two college students, Joseph Woodland and Bernard Silver, created this design after they realized that something similar was necessary in order to track huge inventories in rapidly growing supermarkets. The backstory behind this begins when Woodland started working at IBM in 1951. He then persuaded the company to bring in a consultant to learn more barcodes. As he considered the needs of grocery stores in the future, he based his initial idea on Morse Code. But rather than use dots and dashes, he lengthened them into a series of both wide and thin lines, thus creating the first lineal barcode. Developing this further, the vertical pattern of lines were then arranged into a circle
同义替换：「addressing the need」↔「realized that something similar was necessary」，「effective way to create an automated scanning system」↔「creating the first lineal barcode」
答案：the problem of how to read the code
原文定位：Meanwhile, a scanner that could read these codes was also in simultaneous development. Finally in 1952, the Bull’s-Eye code and linear version were patented, along with the mechanical and electrical scanner systems to read them. IBM suggested that they buy out the patent, but did not agree to match their price as they didn’t think the product was marketable enough at that point. However, Philco did match their price, eventually selling the patent to RCA
同义替换：「the problem of how to read the code」↔「a scanner that could read these codes」
答案：how the idea was eventually put into practice
原文定位：It was not until 1967, when RCA started promoting the Bullseye to the grocery industry, that it was even used. One Kroger Grocery store agreed to be the first to try the Bullseye, as RCA tried to draw attention the amount of potential savings made possible by automating the checkout counter. However, even though the Bullseye didn’t need as much scanner orientation, the code used large quantities of space, and the round design restricted amounts of encoded data. The Bullseye never caught on, as it seems technology at that particular moment in time could not do variable printing, and scanners were still being improved through development
同义替换：「how the idea was eventually put into practice」↔「it was even used」
答案：barcodes help companies keep track of rolling stock
原文定位：At the same time that developers were learning more to increase capabilities of scanning equipment and computer technology, technological progress in auto-identification became focused on the railroad system supporting the retail and manufacturing industries. These freight cars usually go from one end of the country to the other, and are sometimes also borrowed from one rail line by another. Therefore, tracking the freight trains as they move about is extremely challenging
同义替换：「rolling stock」↔「freight cars」
答案：barcodes help companies keep track of rolling stock
原文定位：Initially, barcodes were applied as part of the American railroad system in the late 1960’s. It was at this time when the Association of American Railroads (AAR) put system called KarTrak in place;When railcars passed the rail yard scanners, they would be able to identify them by scanning that information
同义替换：「barcodes help companies keep track of」↔「identify them by scanning that information」，「rolling stock」↔「railcars」
答案：barcode technology becomes more widespread
原文定位：Yet around 10 years later, the very same program fell into disuse after an economic downturn, as well as the system being called unreliable and error prone due contamination with dirt. When the 1980’s arrived, radio tags had become the dominant way of tracking railroad cars. Collins still saw different potential uses for barcodes, especially in industrial settings. He went on to found a company that he named Computer Identics Corporation. General Motors became one of the first plants to monitor production and distribution of car parts by using these barcodes, while another early system was used in a distribution facility
答案：FALSE
原文定位：In 1932, Wallace Flint claimed that it might be feasible to create an automated retail checkout system;It was Flint himself who ended up being a key player in developing UPC code;Two college students, Joseph Woodland and Bernard Silver, created this design [the first barcode/Bullseye barcode] after they realized that something similar was necessary in order to track huge inventories in rapidly growing supermarkets
答案：TRUE
原文定位：As he considered the needs of grocery stores in the future, he based his initial idea on Morse Code. But rather than use dots and dashes, he lengthened them into a series of both wide and thin lines, thus creating the first lineal barcode
答案：TRUE
原文定位：This particular design was chosen for its ability to be scanned from any direction, later gaining the apt nickname of the “Bullseye barcode.” Two college students, Joseph Woodland and Bernard Silver, created this design after they realized that something similar was necessary in order to track huge inventories in rapidly growing supermarkets. The backstory behind this begins when Woodland started working at IBM in 1951. He then persuaded the company to bring in a consultant to learn more barcodes.

答案：A though the code designs were small, they could encode large amounts of data

But rather than use dots and dashes, he lengthened them into a series of both wide and thin lines, thus creating the first lineal barcode;This particular design [circular Bullseye barcode] was chosen for its ability to be scanned from any direction
答案：B the economy fell into a slump
