Read the following article and select the best answer. Article: Those accustomed to looking through thousands of books in big bookstores may find Japan's Morioka Shoten a little strange.That's because this tiny bookstore that is located in luxury shopping district of Ginza,in Tokyo offers just one title to its customers. Opened in May 2015,Morioka Shoten(Japanese for bookstore)is the brainchild of Yoshiyuki Morioka.The experienced bookseller began his career as a bookstore clerk in Tokyo's Kanda district before branching out to open his own store.It was here while organizing book readings that he realized that customers usually came into the store with one title in mind.Morioka began to wonder if a store could exist by selling many copies of just one single book.In November 2014,he partnered with his two friends,to establish a unique bookstore with the idea'A Single Room,A Single Book.' Like its offering,the bookstore is simple.The selections that are picked by Morioka change weekly and vary widely to attract customers with different interests.Recent choices include The True Deceiver,all award-winning Swedish novel by Tove Jansson,Hans Christian Andersen's Fairy Tales.and a collection of artist Karl Blossfeldt's photography of plants.Morioka has also displayed books written by famous Japanese authors Mimei Ogawa and ito Akagi. To highlight his single offering,Morioka often uses clever methods.For example,when selling a book about flowers,he decorated his shop with the ones that had been mentioned in the book.He also encourages featured authors to hold multiple talks and discussions so they can connect with customers.Morioka says his ultimate goal is for the customers to perience being inside a book,not just a bookstore! Risky as the idea might seem,things appear to be going well.Morioka says he has sold over 2,100 books since he opened it.Things can only get better given that his bookstore is becoming increasingly popular not just among the locals but also visitors from other countries* Question: What does the author think of Morioka's bookstore? - Boring. - Unrealistic - Optimistic. - Funny.
Optimistic.

Read the following article and select the best answer. Article: A blind baby is doubly handicapped. Not only is it unable to see, but because it cannot receive the visual stimulus from its environment that a sighted child does, it is likely to be slow in intellectual development. Now the ten-month old son of Dr. and Mrs. Dennis Daughters is the subject of an unusual psychological experiment designed to prevent a lag in the learning process. With the aid of a sonar-type electronic that he wears on his head, infant Dennis is learning to identify the people and objects in the world around him by means of echoes . The device is an improvement of the "Sonicguide", an instrument produced by Telesensory Systems, Inc., of Palo Alto, Calif, and used by blind adults in addition to a smart or guide dog. As adapted for Dennis, it consists of a battery-powered system about the size of a half dollar that is on a headgear. A transmitter sends out an ultrasonic pulse that creates an 80 degree cone of sound at 6 feet. Echoes from objects within the cone are perceived (felt) as sounds that vary in pitch and volume with the size and distance of the object. The closer an object is, the lower the pitch, and the larger the object, the louder the signal. Hard surfaces produce a sharp ping, while soft ones send back signals with a slightly fuzzy quality. An object slightly to the right of Denny's sends back a louder sound to his right ear than to the left. Thus , by simply moving his head right and left and up and down, he can not only locate an object but also get some notion of its shape and size, thanks to the varying qualities of sounds reaching his ears as the cone of ultrasound passes _ . Dennis likes to use the device to play a kind of peek-a-boo with his mother. Standing on her knee and facing her directly, he receives a strong signal in both ears. By turning his head away, he makes her seem to disappear. "From the first time he wore it," says Mrs. Daughters, "it was like a light going on in his head." What remains to be determined is how well the device will help Dennis cope with... Question: What can we learn about infant Dennis' device? - Its first design was designed for blind adults. - Its battery is as small as a half-dollar coin. - It is functionally similar to a sane and guide dog. - It has been improved by Telesensory Systems, Inc.
Its first design was designed for blind adults.

*Question*
Read the following article and select the best answer. Article: The Internet is full of headlines that grab your attention with buzzwords . But often when we click through, we find the content hardly delivers and it wastes our time. We close the page, feeling we've been cheated. These types of headlines are called "click bait". A headline on Busin,esslnsider.com reads: "This phrase will make you seem more polite". First, when you click through, you find another headline: "Four words to seem more polite." Then, on reading the article, you find it's actually an essay about sympathy. And what are the four words? They're "Wow, that sounds hard." On some video websites, you might encounter headlines such as "Here's what happens when six puppies visited a campus". Turns out it's just some uneventful dog footage . Nowadays, with the popularity of social media, many news outlets tweet click bait links to their stories. These tweets take advantage of the curiosity gap or attempt to draw the reader into a story using a question in the headline. These click bait headlines are so annoying that someone is attempting to save people time by exposing news outlet click bait through social media. The Twitter account @SavedYouAClick, run by Jake Beckman, is one such example. Beckman's method is to grab tweets linking to a story and retweet them with a click-saving comment. For example, CNET tweeted "So iOS 8 appears to be jailbreakable but...", with a link to its coverage of Apple's product announcements. Beckman retweeted it with this comment attached: "... it hasn't been jailbroken yet." Since founding the account, Beckman's Twitter experiment has brought him more than 131,000 followers. Beckman said that @SavedYouAClick is "just my way of trying to help the Internet be less temble." Asked about his goal, he said, "I'd love to see publishers think about the experience of their readers first. I think there's an enormous opportunity for publishers to provide readers with informative updates that include links so you can click through and read more.
