They could barely ask the two guides questions when they were climbing. （"A Grand Safari in Tanzania")

It is, everyone agrees, a huge task that the child performs when he learns to speak, and the fact that he does so in so short a period of time challenges explanation.

Language learning begins with listening. Individual children vary greatly in the amount of listening they do before they start speaking, and late starters are often long listeners. Most children will "obey" spoken instructions some time before they can speak though the word obey is hardly accurate as a description of the eager and delighted cooperation usually shown by the child. Before they can speak, many children will also ask questions by gesture and by making questioning noises.

Any attempt to trace the development from the noises babies make Io their first spoken words leads to considerable difficulties. It is agreed [hat they enjoy making noises, and that during the first few. months one or two noises sort themselves out as particularly indicative of delight, distress, sociability, and so on. But since these cannot be said to show the baby's intention to communicate they can hardly be regarded as early forms of language. It is agreed, too, that from about three months they play with sounds for enjoyment, and that by six months they are able to add new sounds to their repertoire. This selfimitation leads on to deliberate imitation of sounds made or words spoken to them by other people. The problem then arises as to the point at which one can say that these imitations can be considered as speech.

By "... challenges explanation" the author means that ______.

A．no explanation has been made up to now

B．no explanation is necessary for such an obvious phenomenon

C．it's no easy job to provide an adequate explanation

D．it's high time that an explanation was provided

Language learning begins with listening. Individual children vary greatly in the amount of listening they do before they start speaking, and late starters are often long listeners. Most children will "obey" spoken instructions sometime before they can speak, though the world "obey" is hardly exact as a description of the eager and delighted cooperation usually shown by the child. Before they can speak, many children will also ask questions by gesture and by making questioning noises.

Any attempt to discover the development from the noises babies make to their first spoken words leads to considerable difficulties. It is agreed that they enjoy making noises, and that during .the first few months one or two noises sort themselves out as particularly indicative of (表示) delight, suffering and so on. But since these cannot be said to show the baby's intention to communicate, they can hardly be regarded as early forms of language. It is agreed, too, that from about three months they play with sounds for enjoyment, and that by six months they are able to add new sounds to their sound collection. This self-imitation (模仿) leads on to deliberate (深思熟虑的) imitation of sounds made or words spoken to them by other people. The problem then arises as to the point at which one can say that these imitations can be considered as speech.

By saying "the fact... challenges explanation", the author means that ______.

A．no explanation is necessary for such a common case
