Question: Article: It would be hard to find a person in America who has never eaten a hamburger, but this popular food was not originally made in America. The original hamburger can be traded back to the Middle Ages, when Russians ate raw meat that was scraped and shredded with a dull knife and formed into patties , It was called Tartar steak. This was the first step in a long series of developments that eventually resulted in hamburger as we know it today. German sailors picked up the raw meat delicacy in their contacts with Russians and brought it back to their home port of Hamburg. But the people there were unused to eating raw meat , so they broiled the outside of the Russian steak; thus the hamburger steak was born. The hamburger steak was brought ot America in the nineteenth century immigrants. Louis Lasssen, a cook in New Haven, Connecticut, modified the hamburger steak by sandwiching it between two pieces of bread. But the true American hamburger came into existence in St. Louis at the Louisiana Purchase Exposition in 1904. A harried cook at the fair quickly slapped broiled beef patties between buns and served them to a demanding crowd, which gulped them down joyously. At first this new food creation was made from scraps of poorer cuts of meat that were not used for anything else, but before scrapes were not enough. The demand for greater quantities of hamburger could only be met by using more and better cuts . Hamburger stands sprang up all over the country, and a side industry of condiments , such as ketchup and relish, grew

Question: Article: It is amazing to note that the Internet is still such a new device, and yet it is one of the fastest and most powerful media tools. But think about it for a moment. On the Internet, a big online company can be run by two guys out of their garage. So it is only reasonable that people shopping on the Net would be a little _ of the security levels. Internet giants such as Microsoft knew consumer confidence was the key to getting virtual shopping off the ground, and they work hard to make people feel safe to shop online. Credit card companies, too, quickly saw the potential for Internet shopping, and have installed things like online shopping insurance for people. If you ever have a problem with your online credit purchases, many credit card companies will happily refund your money and then set their claws on the company that wronged you. Now that's buying power! There are other bonuses for online shoppers, of course. No line-ups, for one. No annoying mall shopping carts with broken wheels and kids crying because their parents won't get them what they want. When shopping online, consumers can sit down, have a coffee, and wear their slippers, not have to worry about their hair or parking and just click through sale after sale. Comparison shopping couldn't be any easier. And thanks to courier companies getting in on the act, you never need wait longer than a day or two to get those all important purchases delivered right to your door. No wonder so many companies are shaking their heads at traditional advertising and instead looking to the "virtual" world to attract online shoppers.
Question: _ leads to consumers' trust in online shopping.
Options: (A) Shopping law (B) Shopping convenience (C) Internet access (D) Shopping security
