Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: Even as Google plans to test its fleet of self-driving cars on public roads this summer, its business model remains a bit of a mystery. By 2025, as many as 250,000 self-driving vehicles could be sold each year globally, according to a study by an industry research firm. "Vehicles that can take anyone from A to B at the push of a button could transform mobility for millions of people," said Chris Urmson, director of Google's self-driving car project. For now, Google has no plans to sell any of its self-driving cars. They are strictly for research. But they will hit public roads this summer near Google's headquarters in Mountain View, California. Previous testing has taken place only on closed courses. The cars are built to operate without a steering wheel, accelerator or brake pedal. "Our software and sensors do all the work," Urmson said. "The vehicles will be very basic -- we want to learn from them and adapt them as quickly as possible -- but they will take you where you want to go at the push of a button." The prototype are the first of a 100-car fleet the tech giant is building. In the long run, Urmson sees a future of safer roads -- the majority of auto accidents are caused by human error -- and fewer traffic jams. Robotic cars could also shuttle people who can't drive because of age or illness. Google has said that self-driving cars could launch new business models in which people buy the use of vehicles they don't own. The company has already tested other types of self-driving cars on public streets, including modified Lexus sport-utility vehicles, under a special permit program by the California Department of Motor Vehicles that requires a human driver at the controls. The state has issued six other companies permits to operate such cars, including Delphi, Mercedes-Benz, Volkswagen, Tesla, Bosch and Nissan. The vehicles that will be tested on open roads this summer will have removable steering wheels, accelerators and brake pedals to allow "safety drivers" to take control if needed. Google says... Options: A self-driving cars can give driving orders to humans B software and sensors are vital for self-driving cars C self-driving cars are specially designed for the elderly D ordinary vehicles will be replaced by self-driving cars Answer: B software and sensors are vital for self-driving cars Question:

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: Persuasion is the art of convincing someone to agree with your point of view. According to the ancient Greek philosopher Aristotle, there are three basic tools of persuasion: ethos, pathos, and logos. Ethos is a speaker's way of convincing people that she is an honest source. For example, a speaker can develop ethos by explaining how much experience or education she has in the field. After all, you would be more likely to listen to advice about how to take care of your teeth from a dentist than a firefighter. A speaker can also create ethos by convincing people that she is a good person who has their best interests at heart. Pathos is a speaker's way of connecting with a listener's emotions. For example, a speaker trying to convince people to vote for him might say that he alone can save the country from a terrible war. These words are intended to fill them with fear, thus making them want to vote for him. Similarly, a charity organization that helps animals might show pictures of injured dogs and cats, intended to fill the viewers with pity. If they feel bad for the animals, they will be more likely to donate money. Logos is the use of facts, statistics, or other information to make your argument more convincing. An audience will be more likely to believe you if you have data to support your claims. For example, a commercial for soap might tell you that lab tests have shown that their soap kills all 7,000, 000 of the bacteria living on your hands right now. it is more convincing than simply saying "our soap is the best!" Use of logos can also increase a speaker's ethos. Although ethos, pathos, and logos all have their strengths, they are often most effective when they are used together. The next time you listen to a speech, watch a commercial, or listen to a friend trying to convince you to lend him some money, be on the lookout for these ancient Greek tools of persuasion. Options: A ethos B pathos C logos D strengths Answer: B pathos Question:

A: When a speaker tries to move people to tears, the tool of persuasion used by him is _ .

Q: Write a multi-choice question for the following article, with the given choices and answer: Article: Tea vs Coffee Tea and coffee are two of the most widely consumed drinks in the United States. With popularity and interest in tea continuing to grow in recent years, many consumers have recently considered making the switch from coffee to tea, if they have not done so already. All the buzz surrounding tea and coffee may have you wondering, what are the differences? As it turns out, the differences are many and varied. In the US, interest in tea ranges from coast to coast with the highest in Hawaii and California but stretching to the eastern states of Vermont and New York. On the other hand, the highest interest in coffee tends to be concentrated more in the north and western regions , with the highest search volumes appearing in the states of Hawaii, Washington and Minnesota. Differences between tea and coffee also vary in origin and production. All tea comes from the harvested leaves of the Camellia sinensis plant, while there are about 60 different species of coffee plants. Production of tea is quicker and more efficient: Camellia sinensis plants only need to grow for three years before they are ready to process; coffee plants take up to five years. Perhaps the most concerning issue consumers have when considering making the switch to tea is the question of caffeine. The good news is, when it comes to tea and caffeine, there is something for everyone. Unlike coffee, which typically only comes in decaffeinated and regular, there are several varieties of tea available, based on caffeine preference. From herbal teas that are naturally free of caffeine, to high quality green and black teas that offer less than half the caffeine of coffee, to high caffeine teas such as our specially formulated HiCAF(r) blends that contain slightly more caffeine than a cup of coffee, there is a variety sure to suit your needs. As an added bonus, the lower acidity levels in tea tend to be gentler on the stomach for a more comforting pick-me-up. So what is the answer, coffee or tea? If you are looking for the most healthful... Options: A Green tea. B Black tea. C Herbal tea. D HiCAF(r) blends. Answer: C Herbal tea. Question:
