Read the following passage and mark the letter A, B, C, or D to indicate the answer to each of the question.

Robots are useful for exploring and working in space. In particular, many robots have been sent to explore Mars. Such robots have usually looked like a box with wheels. Though these robots are useful, by their very nature they are unreliable, extremely expensive, and they break easily. Also, they cannot do very many tasks. Because of these problems, scientists have been developing a new and unusual kind of robot. These new robots move like snakes, so they have been given the name "snakebots."

The way a snake is shaped lets it get into very small spaces, like cracks in rocks. It can also push its way below the ground or climb up different kinds of objects, like high rocks and trees. Such abilities account for the usefulness of a robot designed like a snake. A snakebot would be able to do these things, too, making it much more effective than regular robots with wheels, which easily get stuck or fall over. Since they can carry tools, snakebots would be able to work in space, as well. They could, for example, help repair the International Space Station.

But how can such a robot shape be made? A snakebot is built like a Chain made of about thirty parts, or modules. Each module is basically the same in that they all have a small computer and a wheel to aid movement. The large computer in the "head” of the snake makes all of the modules in a snakebot work together.

The modular design of the snakebot has many advantages. If one module fails, another can be added easily. Snakebot modules can also carry different kinds of tools, as well as cameras. Since each module is actually a robot in itself, one module can work apart from the rest if necessary. That is, all the modules can separate and move on their own, and then later, reconnect back into a larger robot. Researchers are also trying to develop snakebots made of a special kind of plastic that can change its shape using electricity, almost like animal muscles. Snakebots made with this plastic will be very strong and hard to break.

Overall, the snakebot design is much simpler than that of common robots. Thus, snakebots will be much less expensive to build. For example, a robot recently sent to Mars cost over a hundred million dollars, whereas snakebots can cost as little as a few hundred dollars. With their versatility and affordability, snakebots seem to be the wave of the future, at least as far as space robots are concerned.

“Since each module is actually a robot in itself, one module can work apart from the rest if necessary. That is, all the modules can separate and move on their own, and then later, reconnect back into a larger robot.” (Vì bản thân mỗi mô đun này thật sự đã là một con rô bốt, chúng có thể tách ra khỏi những mô đun còn lại để làm việc đơn độc nếu cần thiết. Đó là, tất cả các mô đun có thể tách ra và di chuyển độc lập, rồi sau đó kết nối trở lại với nhau thành một con rô bốt lớn hơn).

Câu 9:

Read the following passage and mark the letter A, B, C, or D to indicate the answer to each of the question.

The majority of medium and large companies pay higher wage rates to men than to women, according to the latest government figures. The disparity, known as the gender pay gap, reflects the different average hourly salaries earned by men and women. The government data showed 74% of firms pay higher rates to their male staff. just 15% of businesses with more than 250 employees pay more to women. As many as 11% of firms said there is no difference between the rates paid to either gender.

Unlike pay inequality - which compares the wages of men and women doing the same job - a gender pay difference at a company is not illegal, but could possibly reflect discrimination. The average gender pay gap across all medium and large-sized firms is now 8.2%, as measured by median pay. in other words, men typically earn over 8% more per hour than women. Among those with the largest gender pay gap are airlines such as Tui and Easyjet, and banks including Virgin Money, the Clydesdale and TSB. Easyjet has said its pay gap of 45.5% is down to the fact that most of its pilots are male, while most of its more modestly paid cabin crew are female. Tui Airways - where men earn 47% more than

214women - has the same issue. Many banks also appear to have a gender bias on salaries. The Bank of England's wage rate for men is 24% higher than for its female employees.

By law, all firms with more than 250 staff must report their gender pay gap to the government by 4 April this year. So far only 1,047 firms have complied, leaving another 8,000 to go. Carolyn Fairbairn, director general of the CBI, denied companies were dragging their feet in reporting the data. "I don't see a reluctance," she told the Today programme. "I think this is genuinely quite difficult data to find, it is often sitting on different systems and firms are working very hard towards that deadline.

Câu 11:

The bad news in the lune jobs numbers, released Friday, is also the good news. The unemployment rate rose to 4 percent last month, from 3.8 percent, which in many contexts would be reason to worry (25) _____ a softening economy. But the details of this particular jump in the jobless rate actually imply good things for the economy.

The labor force rose by 601,000 people last month, driving the proportion of the civilian adult population that is either working or looking for work up by 0.2 percentage points, to 62.9 percent. The unemployment rate rose because not all of the people looking for work found it immediately. That suggested they were ready and willing to (26) _____ the jobs that employers have kept creating at a healthy rate — an additional 213,000 positions in June alone. The month-to-month swings in the size of the labor force can be large because of (27) _____ error. So this may prove to be a random blip that is erased as more data become available.

But taken at face value, it’s a sign that the hot job market is succeeding at pulling people off the sidelines and into the work force. It’s easy to imagine people (28) _____ have become disengaged from the work force who, in this tightening job market, are more likely than they were a few years ago to see help wanted signs everywhere, (29) _____ to have friends and acquaintances urge them to start working.
