If women are encouraged by equal pay to take full-time jobs, they will be unable to do the things they are best at doing: making a nice home and bringing up children. (Passage 3)

When a human infant is born into any community in any part

of the world it has two things in common with any infant, pro- 【M1】__

vided neither of them have been damaged in any way either be- 【M2】__

fore or during birth. Firstly, and most obviously, newborn chil-

dren are completely helpless. Apart from a powerful capacity to

pay attention to their helplessness by using sound, there is noth- 【M3】__

ing the newborn child can do to ensure his own survival. With-

out care from some other human being or beings, be it mother,

grandmother, or human group, a child is very unlikely to sur-

vive. This helplessness of human infants is in marked contrast

with the capacity of many newborn animals to get on their feet 【M4】__

within minutes of birth and run with the herd within a few

hours. Although young animals are certainly in risk, sometimes 【M5】__

for weeks or even months after birth, compared with the human

infant they very quickly develop the capacity to fend for them. 【M6】__

It is during this very long period in which the human infant

is totally dependent on the others that it reveals the second fea- 【M7】__

ture which it shares with all other undamaged human infants, a

capacity to learn language. For this reason, biologists now sug-

gest that language be "species-specific" to the human race, that is 【M8】__

to say, they consider the human infant to be genetic programmed 【M9】__

in such way that it can acquire language. This suggestion implies 【M10】__

that just as human beings are designed to see three-dimensionally

and in colour, and just its they arc designed to stand upright

rather than to move on all fours, so they arc designed to learn

and use language as part of their normal development as well-

formed human beings.
