Input: Consider Input: Article: Mary went out at night. She never forgot the night when she met a robber many years ago. That evening, she was invited to a birthday party which lasted until two o'clock in the morning. Without company Mary walked along the quiet street. Suddenly from the shadow of a dark building a tall man with a sharp knife in his right hand ran out at her. "Good evening, lady," the man said in a low voice, "I don't think you wish to die here." "What do you want?" Mary asked. "Your earrings .Take them off!" Slowly Mary's eyes looked down. She tried to cover her necklace with the collar of her overcoat while she used the other hand to take off both of her earrings, and then she quickly threw them on the ground. "Take them and let me go." she said. The robber looked at her only feeling uncertain. He saw the girl didn't care for the earrings at all, only trying to protect the necklace. He realized the necklace would cost more. So he said, "Give me your necklace." "Oh, sir. It's not worth much. Please let me keep it." "Stop rubbish. Quick!" With shaky hands, Mary took off her necklace. As soon as the robber disappeared, she picked up her earrings and ran as fast as she could to one of her friends. The earrings cost 480 pounds and the necklace the robber had taken away cost only six pounds ten shillings.

Input: Consider Input: 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

Output: D

Input: Consider Input: Article: I log onto a computer at the doctor's office to say I have arrived and then wait until a voice calls me into the examination room. There, a robotic nurse directs me onto a device and then takes my blood pressure. Some time later, in steps the doctor, who is also a robot. He notes down my symptoms and gives me a prescription . I pay for my visit using a credit card machine and return home without having met another human being. When I call my dentist's office and actually get a human being on the line, I am thrilled. And when I see the introduction of yet more self-service checkout stations at the grocery store, I feel like shouting, "When it comes to cashiers, make mine human, please!" After all, human cashiers sometimes give you a store coupon for items you are buying. Even more than that, real-life cashiers often take an interest in particularly cute children, which can brighten a young mother's day. A cashier may also show compassion for an elderly person struggling to get that last penny out of her purse. What technological device would do any of this? I don't want to go back to the Stone Age, but I'm also worried about a world run by machines. Sometimes when you're chatting with someone, you discover things you need to know. Maybe a receptionist needs prayers said for a sick child. Maybe a salesperson can offer a bit of encouragement to a customer who is feeling tired. Machines can be efficient and cost-effective and they often get the job done just fine. But they lack an element so important to everyday life. Call it the spirit, the soul or the heart. It is something no machine will ever have. It is being human that prompts us to smile at others, which may be what they need at that moment.
Question: Why does the author prefer being served by humans rather than by robots?
Options: (A) Robots are indifferent and emotionless. (B) Robots can't provide efficient services. (C) Robots don't offer to give store coupons. (D) Robots are unable to do a job as well as humans.
Output: A
