What is the most important reason that Sequoyah will be remembered

A:He was illiterate. B:California redwoods were named in his honor. C:He recovered from his madness and helped mankind. D:He created a unique alphabet.

If we were asked exactly what we were doing a year ago, we should probably have to say that we could not remember. But if we had kept a book and had written in it an account of what we did each day, we should be able to give an answer to the question. It is the same in history. Many things have been forgotten because we do not have any written account of them. Sometimes men did keep a record of the most important happenings in their country, but often it was destroyed by fire or in a war. Sometimes there was never any written record at all because the people of that time and place did not know how to write. For example, we know a good deal about the people who lived in China 4 000 years ago, because they could write and leave written records for those who lived after them. But we know almost nothing about the people who lived even 200 years ago in central Africa, because they had not learned to wrtie.
Sometimes, of course, even if the people cannot write, they may know something of the past. For most people are proud to tell what their fathers did in the past. This we may call "remembered history", Some of it has now been written down. It is not so exact or so valuable to us as written history is, because words are much more easily changed when used again and again in speech than when copied in writing. But where there are no written records, such spoken stories are often very helpful.

Which of the following ideas is not conveyed in the passage （　）

A:"Remembered history", compared with written history, is less reliable B:Written records of the past plays a most important role in our learning of the human history C:A written account of our daily activities helps us to be able to answer any questions D:Where there are no written records, there is no history

Having taken a room at the hotel which he had been instructed to stay, Smallwood went out; it was a lovely day, early in August, and the sun shone in an unclouded sky. He had not been to Lucerne Since he was a boy, but remembered a covered bridge, though not clearly, a great stone lion and a church in which he had sat, bored yet impressed while they played an organ(风琴) ;and now wandering along a shady quay (码头), he tried not so much to find his way about a half-forgotten scene as to reform in his mind some recollection(回忆) of the shy and eager boy, so impatient for life, who so long ago had wandered there . But it seemed to him that the most lively of his memories was not of himself, but of the crowd; he seemed to remember the sun and the heat and the people; the train was crowded and so was the hotel, the lake steamers were packed and on the quays and in the streets you found your way among the holiday-makers. They were fat and old and ugly and strange.
Now, in wartime, Lucerne was as deserted as it must have been before the world discovered that Switzerland was the play-ground of Europe. Most of the hotels were closed, the streets were empty, the boats for hire rocked(摇晃)idly at the water’s edge and there was none to take them, and in the avenue by the lake the only persons to be seen were serious Swiss taking their dogs for their daily walk . Smallwood felt happy and, sitting down on a bench that faced the water, surrendered (听任)himself to the sensation. The blue water, snowy mountains, and their beauty hit you in the face. So long, at all event, as the fine weather lasted he was prepared to enjoy himself. He didn’t see why he should not at least try to combine pleasure to himself with advantage to his country.
He felt that the city ______.

A:was more crowded than it used to be B:had changed out of all recognition C:had been ruined by becoming a holiday resort D:was quieter than he remembered it
