[Q]: Article: It can greet people, show DVDs and hand out balloons. "Ubiko", a robot-on -wheels with a catlike face, is joining the crew of temporary workers supplied by a Japanese job-referral company, Ubiquitous Exchange, to stores, events and even weddings. Next month, the 44-inch tall robot will be selling mobile phones at a store. Ubiko can be hired as a temporary worker for two hours for 105,000 yen, or $890. "We see this as serious business. There are jobs that robots are better at," Akiko Sakurai said "people do develop a relation with the robot, and it's lovable." The $255,000 robot, which is equipped with a camera and sensors, greets customers with a nasal electronic voice, shows DVDs with a projector in its head and hands out balloons and other goods with wireless remote-controllable arms. Ubiko sounds like a Japanese female name, which often ends with "ko". Tmsuk, the Japanese company that makes the robot, sold three last month to hospital, where they are working as full-time, rather than temporary, receptionists and guides. One of the hospital's robots serves as a receptionist and has been programmed to greet visitors. It also has a touch-panel on its body, and visitors can use it to get directions for where they want to go. "Just give it electricity, and a robot can work for long hours, even do repetitive work, and you don't have to worry about labor laws," Sudo said. Japan's lower birth rate means that in the coming years it could face a labor shortage, and some experts believe robots could be part of the key to that problem. Robots are very popular in Japan partly because of the popularity of cartoons that describe robots as friends and assistants to humans.

[Q]: Article: Do you want to write your password down so that no one can see it, or do you want to send someone a secret message? Knowing how to make an invisible ink message will have you feeling like a secret agent in no time. These are instructions for making invisible ink using baking soda. Difficulty: Easy Time required: A few minutes What you need: Baking soda, Paper, Water, Light bulb, Paintbrush, Measuring cup, Purple grape juice Here's how: There are at least two methods of using baking soda as invisible ink. Mix equal amounts of water and baking soda. Use a paintbrush to write a message onto white paper, using the baking soda solution as "ink". Allow the ink to dry. One way to read the message is to hold the paper up to a heat source, such as a light bulb. The baking soda will cause the writing in the paper to turn brown. The second way to read the message is to paint over the paper with purple grape juice. The message will appear in a different color1. Tips: If you are using the heating method, avoid burning the paper. Baking soda and grape juice react in an acid-base reaction, producing a color1 change in the paper. Grape juice concentrate results in a more visible color1 change than regular grape juice.
Question: is not needed for making invisible ink.

[Q]: Article: As the train approached the seaside town where I was going to spend my holiday, I went into the corridor to stretch my legs.I stayed there for a short while,breathing in the fresh air and exchanging a few words with one of the passengers,whom I had met earlier on the station platform. When I turned to go back to my seat,I happened to glance into the compartment next to mine.Sitting there was a man who many years before had been my neighbor.He was a great talker, I remembered;it used to take hours to get away from him once he began talking.I was not at all sorry when he went to live in another part of London.We had not met since then,nor did I wish to meet him now, when my holiday was about to begin. Luckily at that moment he was much too busy talking to the man opposite him to have the chance to notice me.I slipped back into my compartment,took down my two suitcases and carried them to the far end of the corridor so as to be ready to get off the train as soon as it stopped.The moment the train came to a stop,I called a porter, who _ carried my luggage out of the station and found a taxi for me.As I drove towards the small hotel on the other end of the town,I breathed a deep relief and felt happy that there was little chance that I should run into my boring ex-neighbor again. When I reached the hotel, I went straight to my room and rested there until it was time for dinner.Then I went to the lounge and ordered a drink.I had hardly raised the glass to my lips when a too familiar voice greeted me.I had not escaped from my tiresome neighbor after all !
