Read the following article and select the best answer. Article: Picture the scene: You come home after work feeling too exhausted to cook -only to find a delicious meal worthy of a Michelin-starred restaurant waiting for you. It sounds like a fantasy, but it could be about to come true thanks to a robot chef developed by British scientists. Those scientists have come up with a set of robotic arms so smart that _ are capable of cooking meals all by themselves. The device will be sold from as early as 2017 as part of a purpose-built high-tech kitchen. Scientists at Moley Robotics spent almost 18 years developing the hands. According to its creators, the arms can chop, stir, whisk and baste well enough to recreate almost anything you would care to eat, whether it is a simple home-cooked supper, or a complicated creation designed by a world-class chef. The hands move a little slowly, hovering strangely above the work surface whenever they are not busy, but they imitate human movements closely enough that they can do things such as wiping a spoon on the edge of a pan to prevent drips. Mr Oleynik, who is leading the project, said, "All the things which are possible with the hand are possible here. There is no limitation. A lot of people want to go to Michelin-starred restaurants, but they are quite expensive and may be quite far from the home. This is an opportunity for people to enjoy very good food, and for a reasonable price. " The only cuisine that is off the robot's menu at the moment is sushi, which requires extremely steady pressure and nimble fingers to make, but the team plan to conquer that as well by the time it goes on sale. Question: What can we infer from the passage? - Hands of a robot chef can perform exactly like a cook. - Robot chefs are available at shopping malls. - Michelin-starred restaurants are suitable for many people. - It is uncertain when the robot can cook all kinds of food.
It is uncertain when the robot can cook all kinds of food.

Read the following article and select the best answer. Article: The island of Great Britain being small (compare the size of Australia), the natural place for holiday relaxation and enjoyment is extensive coastline, above all its southern and eastern coasts, and the favorite resort of the mass-population of industrial Lancashire, is on the north-west coast. Distant and little-inhabited area like Northern Scotland, are too remote for the development of large seaside resorts. For most children, going to the seaside suggests a week or fortnight of freedom on the beach, ideally a sandy one providing enough opportunities for the construction of sandcastle, fishing in pool, paddling in shallow water or swimming in deep water. Their parents spend sunny days swimming in the sea and sunbathing on the beach. Not that the British sun can be relied on and the depressing sight of families wandering round the town in old -fashioned and under umbrellas is only too common. However, there are always shops with their tourist souvenirs, plenty of cafes and if the worst comes to the worst, the cinema to offer a refuge. The average family is unlikely to seek accommodation in a hotel as they can stay more cheaply in a boarding-house. There are usually three or four-storeyed Victorian buildings, whose owners spend the summer season letting rooms to a number of couples or families and providing three cooked meals a day at what they describe as a reasonable price, with the hope that in this way they will add enough to their savings to see the winter through. Otherwise there are the camping sites for those who prefer self-catering. Nowadays, even when an increasing number of people fly off to Mediterranean resorts where a well-developed suntan can be assured, or explore in comfort Swiss lakes and mountains or romantic Italian or Spanish cities, the British seaside is still the main attraction for families, especially those with younger children. As they queue for boats trips, cups of tea or ice-cream under gray skies and in dizzling rain, the parents are reliving their own childhood when time... Question: Children enjoy the seaside because _ . - their parents can live and play with them - they can buy what they want there - there are a variety of enjoyable ways of spending time there - they can learn how to build sandcastles, how to swim, etc.
there are a variety of enjoyable ways of spending time there

(Question)
Read the following article and select the best answer. Article: As a child, I was really afraid of the dark and of getting lost. These fears were very real and caused me some uncomfortable moments. Maybe it was the strange way things looked and sounded in my own room at night that scared me so much. There was never complete darkness, but always a streetlight or passing car lights, which made clothes on the back of a chair take on the shape of a wild animal. Out of the corner of my eye, I saw the curtains seem to move when there was no wind. A very low sound in the floor would seem a hundred times louder than in the day. My imagination would run wild, and my heart would beat fast. I would lie very still so that the "enemy" would not discover me. Another of my childhood fears was that I would get lost, especially on the way home from school. Every morning I got on the school bus right near my home. That was no problem. After school, though, when all the buses were lined up along the street, I was afraid that I would get in the wrong one and be taken to some other strange places. On school or family trips to a park or a museum, I wouldn't let the leaders out of my sight. Perhaps one of the worst fears of all I had as a child was that of not being liked or accepted by others. Being popular was so important to me then, and the fear of not being liked was a serious one. One of the processes growing up is being able to realize and overcome our fears. Understanding the things that scared us as children helps us achieve greater success later in life. Question: The author had _ kind(s) of fears when she was a child. - three - two - one - none
