What unusual or unique biological train led to the remarkable diversification and unchallenged success of the ants for over 50 million years? The answer appears to be that they were the first group of predatory eusocial insects that both lived and foraged primarily in the soil and in rotting vegetation on the ground. Eusocial refers to a form of insect society characterized by specialization of tasks and cooperative care of the young; it is rare among insects. Richly organized colonies of the land made possible by eusociality enjoy several key advantages over solitary individuals.

Under most circumstances groups of workers are better able to forage for food and defend the nest, because they can switch from individual to group response and back again swiftly and according to need. When a food object or nest intruder is too large for one individual to handle, nestmates can be quickly assembled by alarm or recruitment signals. Equally important is the fact that the execution of multiple-step tasks is accomplished in a series-parallel sequence. That is, individual ants can specialize in particular steps, moving from one object (such as a larva to be fed) to another (a second larva to be fed). They do not need to carry each task to completion from start to finish - for example, to check the larva first, then collect the food, then feed the larva. Hence, if each link in the chain has many workers in attendance, a sense directed at any particular object is less likely to fail. Moreover, ants specializing in particular labor categories typically constitute a caste specialized by age or body form or both. There has been some documentation of the superiority in performance and net energetic yield of various castes for their modal tasks, although careful experimental studies are still relatively few.

What makes ants unusual in the company of eusocial insects is the fact that they are the only eusocial predators (predators are animals that capture and feed on other animals) occupying the soil and ground litter. The eusocial termites live in the same places as ants and also have wingless workers, but they feed almost exclusively on dead vegetation.

Washington was the first city in history to be created solely for the purpose of governance. Following the Revolution, members of Congress had hotly debated the question of a permanent home for themselves and for those departments – the Treasury, the Patent Office and so on – which even the sketchiest of central governments would feel obliged to establish. In 1790, largely in order to put an end to congressional bickering, George Washington was charged with selecting a site for the newly designated federal district. Not much to anyone’s surprise but to the disappointment of many he chose a tract of land on the banks of the Potomac River, a few miles upstream from his beloved plantation Mount Vernon.

The District of Columbia was taken in part from Virginia and in part from Maryland. At the time it was laid out, its hundred square miles consisted of gently rolling hills, some under cultivation and the rest heavily wooded, with a number of creeks and much swampy land along the Potomac. There is now a section of Washington that is commonly referred to as Foggy Bottom; that section bore the same nickname a hundred and eighty years ago.

Two ports cities, Alexandria and Georgetown, flourished within sight of the new capital and gave it access by ship to the most important cities of the infant nation – Charleston, Baltimore, Philadelphia, New York, Newport, Salem and Portsmouth – and also to the far-off ports of England and the Continent.

* Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 43 to 50.

  All over the country, young people are entering a world of homelessness and poverty, according to a recent report by the housing group, Shelter.

  Nearly 150,000 young people aged between sixteen and twenty-five will become homeless this year, says Shelter. Some of the young homeless may sleep out in the open in such places as the “cardboard city” in London, where people of all ages sleep in the open air in their only home - cardboard boxes. Others may find accommodation in shelters run by voluntary organisations or get a place in a hostel, which gives them board up to ten weeks.

  But who are these people? Those who are seeking a roof over their heads are mostly not runaways but “throwaways” — people who have been thrown out of their homes or forced to leave because of parental divorce, an unsympathetic step-parent or one of many other reasons.

  Take the case of one six teen-year-old schoolgirl, Alice. She did not come from a poor home and had just passed her exams with good results. The Shelter team met her in a hostel where she was doing her physics homework. Her parents had thrown her out of her home for no other reason that she wanted to do Science Advanced Level Exams - which her parents refused her permissionjo do, saying that studying sciences was unladylike!

  Shelter says that the government’s laws do nothing to help these youngsters. Rising rents, the shortage of cheap housing and the cut in benefits for young people under the age of twenty-five are causing a national problem, according to Shelter. The recent changes in the benefit laws mean that someone aged between sixteen and twenty-five gets less than older people and they can only claim state help if they prove that they left home for a good reason.

  Shelter believes that because of the major cuts in benefits to young people, more and more are being forced to sleep on the streets. Shelter also points out that if you are homeless, you can’t get a job because employers will not hire someone without a permanent address; and if you can’t get a job, you are homeless because you don’t have any money to pay for accommodation. It’s an impossible situation.

(Source: FCE success workbook)

The changes in the system of benefits mean that

A. the under twenty-fives can claim money only if they have left home 

B. anyone under twenty-five and not living at home will receive help with food and accommodation 

C. young people cannot claim money unless they are under sixteen or over twenty-five 

D. young people do not receive as much money as those over twenty-five

C       Theo Shelter, một khi những người trẻ tuổi đã buộc phải lên đường, _________ .

A. lợi ích của họ sẽ bị cắt giảm nghiêm trọng

B. họ sẽ không bao giờ trở về nhà một lần nữa

C. họ sẽ thấy khó tìm việc

D. họ sẽ khuyến khích bạn bè của họ làm như vậy

Đáp án C.

Dẫn chứng trong đoạn 6: Shelter also points out that if you are homeless, you can’t get a job because employers will not hire someone without a permanent address; and if you can’t get a job, you are homeless because you don’t have any money to pay for accommodation. - Shelter cũng chỉ ra rằng nếu bạn vô gia cư, bạn không thế kiếm được việc làm vì người chủ sẽ không thuê người không có địa chỉ thường trú; và nếu bạn không thể kiếm được việc làm, bạn vô gia cư vì bạn không có tiền để trả tiền ăn ở.
