Read the following article and select the best answer. Article: This year some twenty-three hundred teenagers (young people aged from 13 to 19) from all over the world will spend about ten months in US homes. They will attend US schools, meet US teenagers, and form impressions of the real America. At the same time, about thirteen hundred American teenagers will go to other countries to learn new languages and gain a new understanding of the rest of the world. Here is a two-way student exchange in action. Fred, nineteen, spent last year in Germany with George's family. In turn, George's son Mike spent a year in Fred's home in America. Fred, a lively young man, knew little German when he arrived, but after two months' study, the language began to come to him. Schools were completely different from what he had expected--much harder. Students rose respectfully when the teacher entered the room. They took fourteen subjects instead of the six that are usual in the United States. There were almost no outside activities. Family life, too, was different. The father's word was law, and all activities were around the family rather than the individual . Fred found the food too simple at first. Also, he missed having a car. "Back home, you pick up some friends in a car and go out and have a good time. In Germany, you walk, but you soon learn to like it." At the same time, In America, Mike, a friendly German boy, was also forming his idea."I suppose I should criticize American schools," he says. "It is far too easy by our level. But I have to say that I like it very much. In Germany we do nothing but study. Here we take part in many outside activities. I think that maybe your schools are better in training for citizens . There ought to be some middle ground between the two. Question: Fred and Mike agreed that _ . - American food tastes better than German food. - Americans and Germans were both friendly - German schools were harder than American schools - There were more cars on the streets in America
**Answer**
German schools were harder than American schools

*Question*
Read the following article and select the best answer. Article: Many people rely on a cup of coffee or two to wake them up in the morning or pick them up during the working day, but now a chemist has come up with a speedy alternative to crafting a cup of coffee. U.S. biochemist Ben Yu has created 'Sprayable Energy,' which claims to be the world's first caffeine - based topical energy spray. He said tired workers can spray a 'shot' of caffeine onto their skin without experiencing a strong buzz, loading up on unnecessary calories or being stuck with a nasty aftertaste like they might get from drinking energy drinks or coffee. The patent-pending caffeine spray is an odourless liquid that is absorbed through the skin and distributed through the body over a number of hours to deliver a caffeine hit that apparently lasts longer than guzzling a cup of coffee. Each small aluminum bottle of Sprayable Energy contains around 160 sprays - the equivalent amount of caffeine to 40 cups of coffee and the creators say it is a much cheaper way of getting a caffeine fix than popping to a cafe. The only active ingredient in the spray is caffeine, which can naturally enter the human body through the skin by passing through cell membranes as it is very similar to nicotine in structure. Each spritz of Sprayable Energy contains around a quarter of the amount of caffeine found in a cup of coffee, but apparently has the same effect as a full cup. The website said: 'The reason for this is our product not being ingested, isn't almost entirely metabolised by the liver before entering your system and becoming available to your body.''Thus, a smaller amount of caffeine can have just the same effect as a very large amount of caffeine ingested through an energy drink or cup of coffee. Sprayable Energy's website recommends that users apply the spray in places where they normally spritz perfume, such as the neck or wrists, but warns users not to exceed 20 sprays a day. It claims that after spraying the product on the skin, users will feel 'awake and focused without being over-stimulated', which is common... Question: We can conclude from the passage that _ - Sprayable Energy can not be permitted to be used by people now. - Sprayable Energy has not already gone into mass production - Each spritz of Sprayable Energy has the same effect as a full cup of coffee - Sprayable Energy is well received by flagging workers.
**Answer**
Sprayable Energy has not already gone into mass production
