6、 阅读下列短文,回答题。。

A man examined the ears of hundreds of children in Europe and found that about one quarter of the children were a little deaf( 聋的).
These children did not know it themselves; they thought they could hear as well as anybody. The teachers thought so, too, only they were quite sure that those special children were the dull ones in the school. No doubt they were rather surprised when the man who examined them found that generally the dull ones were also the deaf ones.
The same man next went to a school in England. There he asked the teachers to pick out seventy bright children and seventy dull children for him to examine. He found about twice as many deaf among the seventy who were dull as among the seventy who were bright. Dullness and deafness often go together.
From there he went to another school, where he found that most of the bright children could hear his watch tick (嘀嗒响) when it was as far from their ears as fifty inches, while most of the dull children could not hear it unless it was as near to them as thirty inches.
All these experiments showed that when children are a little deaf they seem dull. But very often deaf children are not really dull. After doctors cure them, they can be as bright as anybody. The chances are that the better we hear the quicker we shall understand. It is important, therefore, to have good hearing.
The children who were a little deaf were quite sure that__________.
A.they couldn't hear as well as others
B.they could hear no worse than anybody
C.they were the dull ones in the school
D.they were as bright as anybody
