Article: He must have been completely lost in something he was reading because I had to tap on the windshield to get his attention."Is your cab available ?"I asked when he finally looked up at me.He nodded,then said apologetically as I settled into the back seat,"I'm sorry,but I was reading a letter."He sounded as if he had a cold."I am not in a hurry,"I told him."Go ahead and finish your letter."He shook his head."I've read it several times already.I guess I almost know it by heart." "Letters from home always mean a lot" I said. "This isn't family," he replied."although it might just as well have been family.Old Ed was my oldest friend.In fact,we used to call each other 'Old Friend'--when we'd meet.I'm not much good at writing." "I don't think any of us keep up our correspondence too well,"I said."I know I don't,but I take it he's someone you've known quite a while?" "All my life.We were kids together, went to school together and all the way through high school.""There are not too many people who've had such a long friendship,"I said."Actually,"the driver went on,"I hadn't seen him more than once or twice year over the past 25 or 30 years because I moved away from the old neighborhood and you kind of lose touch even though you never forget." "You said 'was'.Does that mean---?" he nodded."A couple of weeks ago." "I'm sorry" He didn't say anything more,and we rode on in silence for a few minutes.But I realized that Old Ed was still on his mind when he spoke again,almost more to himself than to me." "I should have kept in touch with him." "Well,'' I agreed,"we should all keep in touch with old friends more than we do.But things come up and we just don't seem to find the time."

Article: There are two dangers to be guarded against in old age. One of these is undue absorption in the past. It does not do to live in memories, in regrets for the good old days, or in sadness about friends who are dead. One's thoughts must be directed to the future and to things about which there is something to be done. It is unwise to be too attached to the youth in the hope of sucking vigor from its vitality. When your children are grown up they want to live their own lives, and if you continue to be as interested in them as you were when they were young, you are likely to become a burden to them, unless they are cold to you. I think that a successful old age is easiest for those who have strong impersonal interests involving appropriate activities. It is in this sphere that long experience is really fruitful, and it is in this sphere that the wisdom born of experience can be exercised without being oppressive. It is no use telling grown-up children not to make mistakes, both because they will not believe you, and because mistakes are an essential part of education. But if you are one of those who are incapable of impersonal interests, you may find that your life will be empty unless you concern yourself with you children and grandchildren. In that case you must realize that while you can still _ them material services, such as making them an allowance or knitting them jumpers, you must not expect that they will enjoy your company. Some old people are afraid of death. But in fact the best way is to make your interests gradually wider and ore impersonal. An individual human existence should be like a river-small at fist, rushing passionately past rocks and over waterfalls. Gradually the river grows wider and the banks move back and in the end they become mixed in the sea without any visible break. The old man who can see life in this way will not suffer from the fear of growing old and death. Question: What's the best title of this passage? Yes or no, is the answer "Growing Old Successfully"?
(A).
Yes

Article: Prolonging human life has increased the size of the human population. Many people alive today would have died of childhood diseases if they had been born 100 years ago. Because more people live longer, there are more people around at any given time. In fact, it is a decrease in death rates, not an increase in birthrates, that has led to the population explosion. Prolonging human life has also increased the dependency load. In all societies, people who are disabled or too young or too old to work are dependent on the rest of society to provide for them. In hunting and gathering cultures, old people who could not keep up might be left behind to die. In times of , infants might be allowed to die because they could not survive if their parents starved, where as if the parents survived they could have another child. In most contemporary societies, people feel a moral to keep people alive whether they can work or not. We have a great many people today who live past the age at which they want to work or are able to work; we also have rules which require people to retire at a certain age. Unless these people were able to save money for their retirement, somebody else must support them. In the United States many retired people live on social security checks which are so little that they must live in near poverty. Older people have more illnesses than young or middle-aged people; unless they have wealth or private or government insurance, they must often "go on welfare" if they have a serious illness. When older people become or too weak and ill to care for themselves, they create grave problems for their families. In the past and in some traditional cultures, they would be cared for at home until they died. Today, with most members of a household working or in school, there is often no one at home who can care for a sick or weak person. To meet , a great many nursing homes and hospitals have been built. These are often profit making organizations, although some are sponsored by religious and other nonprofit...
