Which of the following statements is CORRECT about the origin of language? [orig

How men first learnt to invent words is unknown, in other words, (14)the origin of language is a mystery. All we really know is that men, unlike animal, somehow invented certain sounds to express thoughts and feelings, actions, and things, so that they could communicate with each other, and that later they agreed upon certain signs, called letters, which could be combined to represent those sounds, and which could be written down. These sounds, whether spoken or written in letters are called words.(15)The power of words, then, lies in their associations—the things they bring up before our minds. Words become filled with meaning for us by experience, and the more we read and learn, the more the number of words that mean something to us increases. Great writers are those who not only have great thoughts but also express these thoughts in words, which appeal powerfully to style. Above all, the real poet is a master of words. He can convey his meaning in words which sing like music and which by their position and association can move men to tears.(16)We should therefore learn to choose our words carefully and use them accurately, or they will make our speech silly and out of place.
