Example Input: Article: Americans often plan social gatherings on short notice, so don't be surprised if you get invited to someone's home or to see a movie or baseball game without much warning. If the time is convenient for you, surely accept their invitation. But if you're busy, don't be afraid to _ the invitation, perhaps suggesting a time that would be better. Your host won't be shamed. Invitations are usually sent in person or over the telephone. The main exception is for some formal occasions, in which case a written invitation will be mailed. You would normally receive a written invitation to a wedding . For a casual dinner invitation, don't arrive more than 5 minutes early, because your host may still be preparing for your visit. Arriving more than 10 minutes late is considered rude if very few people were invited. If many people were invited, it's OK to arrive a little late, even as much as half an hour late. For example, it's OK to arrive late for a party, for a potluck dinner or for a social gathering inviting a large group of people. If you're invited for dinner, it's proper to bring the host a bottle of wine, a gift basket of fruit, a box of candy , or a bouquet of flowers. Don't bring roses, as men often give roses to women on a date . If you wish to thank the host for his or her hospitality , it's right to call or send a brief written thank-you note the next day.
Answer: something about American social visits.

Example Input: Article: The Process of Ageing At the age of twelve years, the human body is at its most vigorous. It has yet to reach its full size and strength, and its owner his or her full intelligence; but at this age the possibility of death is least. Earlier, we were infants and young children, and consequently more vulnerable ; later, we shall undergo a progressive loss of our vigour and resistance which, though vague at first, will finally become so steep that we can live no longer, however well we look after ourselves, and however well society, and our doctors, look after us. This decline in vigour with the passing of time is called ageing. It is one of the most unpleasant discoveries which we all make that we must decline in this way, that if we escape wars, accidents and disease we shall eventually "die of old age", and that this happens at a rate which differs little from person to person, so that there are heavy odds in favor of our dying between the ages of sixty-five and eighty. Some of us will die sooner, a few will live longer -- on into a ninth or tenth decade. But the chances are against it, and there is a virtual limit on how long we can hope to remain alive, however lucky and physically strong we are. Normal people tend to forget this process unless and until they are reminded of it. We are so familiar with the fact that man ages, that people have for years assumed that the process of losing vigour with time, of becoming more likely to die the older we get, was something self-evident, like the cooling of a hot kettle or the wearing-out of a pair of shoes. They have also assumed that all animals, and probably other organisms such as trees, or even the universe itself, must in the nature of things "wear out". Most animals we commonly observe do in fact age as we do, if given the chance to live long enough; and mechanical systems like a wound watch, or the sun, do in fact ran out of energy in accordance with the second law of thermodynamics . But these are not similar or equivalent to what happens when man ages. A run-down watch is still a watch and can be rewound. An old watch, by contrast, becomes so worn and unreliable that it eventually is not worth mending. But a watch could never repair itself -- it does not consist of living parts, only of metal, which wears away by friction . We could, at one time, repair ourselves -- well enough, at least, to overcome all but the most instantly fatal illnesses and accidents. Between twelve and eighty years we gradually lose this power, an illness which at twelve would knock us over, at eighty can knock us out, and into our grave. If we could stay as vigorous as we are at twelve, it would take about 700 years for half of us to die, and another 700 for the survivors to be reduced by half again.
Answer: people usually are unhappy when they are reminded of ageing

Example Input: Article: Buck did not read the newspapers,or he would have known that trouble was coming,not only for himself,but for every big dog,strong of muscle and with long,warm hair in California.Men had found gold in the Yukon,and these men wanted big,strong dogs to work in the cold and snow of the north. Buck lived at a big house in the sunkissed Santa Clara valley.Judge Miller's place,it was called.There were large gardens and fields of fruit trees around the house,and a river nearby.In a big place like this,of course,there were many dogs.There were house dogs and farm dogs,but they were not important.Over this great land Buck ruled.Here he was born and here he had lived the four years of his life.He was not so large--he weighed only one hundred and forty pounds.But he had saved himself by not becoming a mere housedog.Hunting and outdoor delights had kept down the fat and hardened his muscles.He went swimming with Judge Miller's sons,and walking with his daughters.He carried the grandchildren on his back,and he sat at Judge Miller's feet in front of the warm library fire in winter.During the four years,he had a fine pride in himself which came of good living and universal respect.He was king of Judge Miller's place. But this was 1897,and Buck did not know that men and dogs were hurrying to northwest Canada to look for gold.And he did not know that Manuel,one of the gardener's helpers,was in bad need of money for his hobby of gambling and for his large family.One day,the Judge was at a meeting and the boys were busy organizing an athletic club.No one saw Manuel and Buck go off on what Buck imagined was merely an evening walk.Only one man saw them arrive at the railway station.This man talked to Manuel,and gave him some money.Then Manuel tied a piece of rope around Buck's neck. Buck had accepted the rope with quiet dignity .He had learned to trust in men he knew and to give them credit.But when the ends of the rope were placed in the stranger's hands,Buck roared,and was surprised when the rope tightened around his neck,shutting off his breath.In extreme anger,he jumped at the man.The man caught him and suddenly Buck was thrown over on his back.Then the rope tightened cruelly while Buck struggled,his tongue out of his mouth.Never in all his life had he been so badly treated.Never in all his life had he been so angry.For a few moments he was unable to move,and it was easy for the two men to put him into the train. When Buck woke up,the train was still moving.The man was sitting and watching him,but Buck was too quick for him and he bit the man's hand hard.Then the rope was pulled again and Buck had to let go. That evening,the man took Buck to the back room of a bar in San Francisco.The barman looked at the man's hand and trousers covered in blood. "How much are they paying you for this?"he asked. "Only get fifty dollars." "And the man who stole him--how much did he get?"asked the barman. "A hundred.He wouldn't take less." "That makes a hundred and fifty.It's a good price for a dog like him." Buck spent that night in a cagelike box.He could not understand what it all meant.What did they want with him,these strange men?And where were Judge Miller and the boys? The next day Buck was carried in the box to the railway station and put on a train to the north.
