Write a multi-choice question for the following article, with the given choices and answer: Article: Many people rely on a cup of coffee or two to wake them up in the morning or refresh them during the working day, but now a chemist has come up with a speedy alternative to drinking 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 noise, taking in unnecessary calories or being stuck with a nasty aftertaste like they might get from drinking energy drinks or coffee. The tasteless caffeine spray is absorbed through the skin and spread through the body over a number of hours to deliver a caffeine hit that lasts longer than drinking a cup of coffee. The only active ingredient in the spray is caffeine, which is very similar to nicotine in structure. Each spray '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 isn't entirely metabolized by the liver before entering your system and becoming available to your body." Sprayable Energy's website recommends that users apply the spray in places where they normally spritz perfume, such as wrists, the neck or behind the ears, but warns users not to exceed 20 times a day. It claims that after spraying the product on the skin, users will feel awake and focus without being over-excited, which is common with coffee and energy drinks. Options: A "Sprayable Energy" contains caffeine as well as nicotine. B The liver can metabolize in caffeine before it enters your system. C Whenever you feel tired, you can spray the product. D After spraying "Sprayable Energy", you'll get rid of tiredness. Answer: D After spraying "Sprayable Energy", you'll get rid of tiredness. Question:

Write a multi-choice question for the following article, with the given choices and answer: Article: Walking is so simple and convenient that it couldn't possibly count as exercise, right? Wrong. Study after study shows that regular walking can help you lose weight and reduce your risk of heart disease. The study published in Diabetes Research in Clinical Practice shows that the blood pressure of the overweight men being tested improved and the amount of body fat greatly decreased. That's good news, because walking has now become the most popular fitness activity in the United States. Convenient, simple, and gentle on the joints, walking is perhaps the easiest form of exercise to maintain. According to a survey, four out of five women who start a walking program continue to walk, while half of women who attempt other types of aerobic exercise , such as swimming, drop out during the first few months. Here are some basics for walking exercise. Walk at a pace that makes you breathe heavily, but still able to talk. Your goal, first and foremost, is to walk five days a week, 30 minutes a walk. Do that, and you are getting the base-level amount of exercise that research says should maintain your health and vigor . Walk for as long as you are comfortable the first week, even if it is just to your mailbox and back. Each following week, increase that amount by no more than 10 percent. Start every walk with five minutes of easy-paced walking, about the same pace at which you do shopping, to get your body warmed up. Then, cool down at the end of each walk with another five minutes of easy-paced walking. This allows your heart rate to gradually speed up and slow down. Options: A To help reduce your blood pressure. B To help reduce your risk of heart disease. C To help your body lose fat. D To help your heart rate change gradually. Answer: D To help your heart rate change gradually. Question:
