Read the following article and select the best answer. Article: Security guard, truck driver, salesperson--year after year, these jobs appear on lists of the unhappiest careers. Although many factors can make a job unhappy, unusual hours, low pay, nochance for advancement -- these three gigs stand out for another reason: a lack of small talk. Psychologists have long said that connecting with others is central to well-being, but just how much conversation we require is under investigation. In one study, researchers eavesdropped on undergraduates for four days, then cataloged each overheard conversation as either small talk (What do you have there? Popcorn?(Yummy!) or serious (So did they get divorced soon after?). They found that the second type related with happiness--the happiest students had roughly twice as many serious talks as the unhappiest ones. Small talk, meanwhile, made up only 10 percent of their conversation, versus almost 30 percent of conversation among the least content students. However, don't just consider chat worthless yet. Scientists believe that small talk could promote linking. Chatting with strangers could brighten your morning. In a series of experiments, psychologists gave Chicago travelers varying directions about whether to talk with fellow train passengers something they typically avoided. Those told to chat with others reported a more pleasant journey than those told to enjoy your being alone or to do whatever they normally would. None of the chatters reported being rejected. And the results held for introverts and extroverts alike which makes sense, since acting extroverted has a positive effect on introverts. Small talk can also help us feel connected to our surroundings. People who smiled at, made eye contact with, and briefly spoke with their Starbucks reported a greater sense of belonging than those who rushed through the business. Similarly, one not yet published paper found that when volunteers broke the silence of the Tate Modern to chat with gallery goers, the visitors felt happier and more connected to the exhibit than those who... Question: The author used the Tate Modern example to demonstrate that _ . - connecting with others is key to our happiness - unserious conversation could promote bonding - small talk can help us feel connected to our surroundings - smiling can help people gain a great sense of belonging
small talk can help us feel connected to our surroundings

(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
