Read the passage carefully and choose the best answer to each question out of the four alternatives and click the button corresponding to it.

Awareness means the capacity to see a coffee pot and hear the birds sing in one's own way, and not the way one was taught. It may be assumed on good grounds that seeing and hearing have a different quality for infants than for grownups and that they are more aesthetic and less intellectual in the first years of life. A little boy sees and hears birds with delight. Then the 'good father' comes along and feels he should 'share' the experience and help his son 'develop'. He says, "That's a jay and this is a sparrow." The moment the little boy is concerned with which is a jay and which is a sparrow, he can no longer see the birds or hear them sing. He has to see and hear them the way his father wants him to. Father has good reasons on his side: since few people can afford to go through life listening to the birds sing, sooner the little boy starts his 'education' the better. Maybe he will be an ornithologist when he grows up.
