Article: Ibrahim became disabled after contracting polio when he was three years old. At first his parents, like many other parents of disabled children in Niger, did not want to send him to school. They were worried he would be laughed at by his classmates. Despite his disability, and his parents' doubts, Ibrahim was determined to go to school. "When I was eight," Ibrahim says, "other kids of my age were going to school while I stayed at home. I did not like that. So, I pestered my parents until they finally let me go to school." Ibrahim's parents sent him to a private school nearby. Although the journey to and from school was a short one, it still wasn't easy for Ibrahim. He had to use his hands to help him move along, protecting them with plastic slippers. But at least he was getting an education. However, after only a year in school, Ibrahim's education was interrupted when his parents separated. His mother did not have the means to continue paying for his tuition. In 2007, Ibrahim received some money to be fitted with a leg brace , corrective shoes and his first pair of crutches . Now that he was more mobile than before, the most important thing for him was to find a way to go back to school. "I wanted to start school again last October," Ibrahim says. "After my mother told me she could not afford it, I went to visit some of my relatives for support. And I collected 5,000 francs CFA (US $8) to pay my tuition for half a year. I will find the rest of the money somehow." Ibrahim attends a school in which he is the only disabled student. According to his teacher, he is among the top five students in a class of 55.

Article: It is one of the most annoying words in the English language and it seems there is no escaping it. The word "huh?" is in worldwide use, a study found. Researchers discovered that languages spoken in countries from Ghana and Laos to Iceland and Italy all include "huh?", or something that sounds very like it. They said that while the study may sound silly, the word is an absolutely necessary part of speech. Without it and similar words, it would be impossible to show that we haven't heard or understood what had been said and this would lead to constant misunderstandings. But while other words used in the same context, such as "sorry" or "what", vary widely across languages, "huh?" remains unchanged. The Dutch researchers carefully studied ten languages from around the world, including Siwu, which is spoken in Ghana, and an Australian Aboriginal language, as well as Italian, Spanish, Dutch and Mandarin Chinese. They analysed tapes of recorded conversations for words that sounded like "huh?" and were used to request that whatever had just been said be repeated. All contained a version of "huh?". The word was also found in another 21 languages. While there were subtle differences in each country, all sounded basically the same. This is surprising because normally unrelated languages will use very different words to describe the same thing. For instance, the Japanese for "dog" is "inu", while the French is "chien". It is thought that languages around the world have developed their own version of "huh?" because the sound is quick and simple to form, as well as being easily understood. The researchers, said that it might seem unimportant to carry out scientific research into a word like "huh?" but in fact this little word is an essential tool in human communication. They also have an answer for those who claim that "huh?" isn't a word. They say that it qualifies because of the small differences in its pronunciation in different languages. It also can be considered a word because it's something we learn to say, rather than a grunt or cry that we are born knowing how to make.
Question: According to researchers, the word "huh?" is very important in speech because of _ .
Options: (A) its stable meaning in language development (B) its important function in communication (C) its simple and easy sound and spelling (D) its popularity in every language
