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.

There are already many, many people who have passed the landmark age of 100. In fact, there are now so many healthy, elderly people that there's a new term for them: the wellderly. These are people over the age of 80 who have no diseases such as high blood pressure, heart disease or diabetes and have never taken medicines for these conditions.

There have been many scientific studies of communities where a healthy old age is typical. These include places like Calabria in southern Italy and the island of Okinawa in Japan.

The small village of Molochio in Calabria has about 2,000 inhabitants. And of these there are at least eight centenarians. When researchers ask people like this the secret of their long life, the answer is almost always to do with diet and is almost always the same: 'I eat a lot of fruit and vegetables.' 'A little bit, but of everything.’ ‘No smoking, no drinking.’

While in the past scientists have looked at things such as diet and lifestyle for an explanation of long life, these days they are investigating genetics. One such researcher is Eric Topol, who says, "There must be genes that explain why these individuals are protected from the aging process."

The new research into long life looks at groups of people who have a genetic connection. For example, one group of interest lives in Ecuador. In one area of the country there are a number of people with the same genetic condition. It's called Laron syndrome. The condition means that they don't grow to more than about one, but it also seems to give them protection against cancer and diabetes. As a result, they live longer than other people in their families. Meanwhile, on the Hawaiian island of Oahu, there's another group of long-lived men, Japanese-Americans. They have a similar gene to the Laron syndrome group.

Back in Calabria, scientists are trying to work out exactly how much of the longevity is due to genetics and how much to environment. By checking public records going back to the 19th century, researchers have reconstructed the family trees of 202 nonagenarians and centenarians. They concluded that there were genetic factors involved.

There are many mistakes that people make when writing their resume (CV) or completing a job application. Here are some of the most common and most serious.

The biggest problem is perhaps listing the duties for which you were responsible in a past position: all this tells your potential employers is what you were supposed to do. They do not necessarily know the specific skills you used in executing them, nor do they know what results you achieved - both of which are essential. In short, they won’t know if you were the best, the worst or just average in your position.

The more concrete information you can include, the better. As far as possible, provide measurements of what you accomplished. If any innovations you introduced saved the organization money, how much did they save? If you found a way of increasing productivity, by what percentage did you increase it?

Writing what you are trying to achieve in life - your objective - is a waste of space. It tells the employer what you are interested in. Do you really think that employers care what you want? No, they are interested in what they want! Instead, use that space for a career summary. A good one is brief - three to four sentences long. A good one will make the person reviewing your application want to read further.

Many resumes list ‘hard’ job-specific skills, almost to the exclusion of transferable, or ‘soft’, skills. However, your ability to negotiate effectively, for example, can be just as important as your technical skills.

All information you give should be relevant, so carefully consider the job for which you are applying. If you are applying for a job that is somewhat different than your current job, it is up to you to draw a connection for the resume reviewer, so that they will understand how your skills will fit in their organization. The person who reviews your paperwork will not be a mind reader.

If you are modest about the skills you can offer, or the results you have achieved, a resume reader may take what you write literally, and be left with a low opinion of your ability: you need to say exactly how good you are. On the other hand, of course, never stretch the truth or lie.
