In comparison with most other places in the world, family identity is rather weak in Britain, especially in England. Of course, the family unit is still the basic living arrangement for most people. But in Britain this definitely means the nuclear family. There is little sense of extended family identity, except among some racial minorities. This is reflected in the size and composition of households.

It is unusual for adults of different generations within the family to live together. The average number of people living in each household in Britain is lower than in most other European countries. The proportion of elderly people living alone is similarly high.

Significant family events such as weddings, births and funerals are not automatically accompanied by large gatherings of people. It is still common to appoint people to certain roles on such
occasions, such as „best man‟ at a wedding, or godmother and godfather when a child is born. But for most people these appointments are of sentimental significance only. They do not imply lifelong responsibility. In fact, family gatherings of any kind beyond the household unit are rare. For most people, they are confined to the Christmas period.

Even the stereotyped nuclear family of father, mother and children is becoming less common. Britain has a higher rate of divorce than anywhere else in Europe except Denmark and the proportion of children born outside marriage has risen dramatically and is also one of the highest (about a third of all births). However, these trends do not necessarily mean that the nuclear family is disappearing. Divorces have increased, but the majority of marriages in Britain (about 55%) do not break down. In addition, it is notable that about three-quarters of all births outside marriage are officially registered by both parents and more than half of the children concerned are born to parents who are living together at the time.

Today, in Britain, many couples, mostly in their twenties or thirties, live together without getting married. Only about 60% of those couples will eventually get married. 40% of children in Britain are born to these cohabiting parents. In 2000, around a quarter of unmarried people between the ages of 16 and 59 were cohabiting in Great Britain. Unmarried couples are also starting families without first being married. Before 1960, this was very unusual, but in 2001, around 23% of births in the UK were to cohabiting couples.

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.

Farming has come a long way since the days of horse-drawn plows, and now it’s heading swiftly into the twenty-first century. Research at Indiana’s Purdue University uses the Navistar Global Positioning System (GPS) to help increase crop yields and reduce chemical use. GPS uses satellite signals to determine location within inches. Under Purdue’s scheme, a farmer out in the field would use a GPS receiver mounted on his vehicle to pinpoint his position. A computer linked to the receiver and programmed with the field’s soil conditions – which can vary widely from one area to another – would tell the farmer precisely where the plant and how much pesticide and fertilizer to use at that specific site. “Currently the number one cost to the famer is chemicals” say Gary Kurtz, a Professor of Agriculture Engineering at Purdue. Site-specific farming can increase yields while reducing chemical use.

But the cost of this new technology may be too high for the small farmer. The cost of taking and testing soil samples every few feet in a farmer’s field is a limiting factor. Soil tests can run $7 to  $8 each. Mark Morgan, assistant Professor of Agriculture Engineering at Purdue and his graduate assistants are working on a sensor to be attached to the front of a farm implement, enabling the farmer to perform his own soil tests on the go.

What does the passage mainly discuss?

A. Technological advances in agriculture

B. The cost of new technology on farming

C. The problems of using computerized machines

D. The rapid evolution of farming
