Recent advances in science and technology have made it possible for geneticists to find out abnormalities in the unborn foetus and take remedial action to rectify some defects which would otherwise prove to be fatal to the child. Though genetic engineering is still at tis infancy, scientists can now predict with greater accuracy, a genetic disorder. It is not yet an exact science since they are not in a position to predict when exactly a genetic disorder will set in. While they have not yet been able to change the genetic order of the gene in germs, they are optimistic and are holding about that in the near future they might be successful in achieving this feat. They have, however, acquired the ability to manipulate tissue cells. However, genetic mis-information can sometimes be damaging for it may adversely affect people psychologically. Genetic information may lead to a tendency to brand some people as inferiors. Genetic information can therefore be abused and its application in deciding the sex of the foetus and its subsequent abortion is now hotly debated on ethical lines. But on this issue geneticists cannot be squarely blamed though this charge has often been leveled at them. It is mainly a societal problem. At present genetic engineering is a costly process of detecting disorders but scientists hope to reduce the costs when technology becomes more advanced. This why much progress in this area has been possible in scientifically advanced and rich countries like the U.S.A., U.K., and Japan. It remains to be seen if in the future this science will lead to the development of a race of supermen or will be able to obliterate illness from this world.
Q: Which of the following is true regarding the reasons for progress in genetic engineering?
Anthropologists who study orangutans, distant cousins of the
human race, find in the animals behavior hints of how our earliest ancestors
may have lived. It has long been accepted that primates originally dwelt in the
treetops and only migrated to the ground as forests began to dwindle. While to
a certain extent, all primates except humans spend at least some time dwelling
in trees, the orangutans, can grow as heavy as 330 pounds and live for decades,
requiring copious amounts of fruits simply to stay alive. Thus, they become
very jealous of the territory where they find their food. Compounding his
territoriality are the breeding habits of orangulants, since females can only
breed every few years and, like humans, give birth not to litters but single
off-spring.
Consequently, orangutans are solitary, territorial animals
who have difficulty foraging in an part of the forest where they were not raised.
Orangutans take from poachers by costums agents undergo incredible hardship on
their return to the wild. Incorrectly relocating a male orangutan is especially
problematic, often ending in the animal’s death at the hands of a rival who
sees not only his territory but also the females of his loosely knit community
under threat from an outsider. While humans, like chimpanzees, are more
gregarious and resourceful then orangutans, the latter provide anthropologists
with useful information about the behavior of prehominid primates and how
apelike behavior influenced out ancestors search for the food and family
beneath the forest canopy.

Through the U.S. prides itself on behing a leader in the
world community, a recent report shows that it lags far behind other industrialized
countries in meeting the needs of its youngest and most vulnerable citizens.
The U.S. has a higher infant mortality rate, a higher proportion of low birth
weight babies, a smaller proportion of babies immunized against childhood
diseases and a much higher rate adolescent pregnancies. These findings,
described as a quiet crisis requiring immediate and far-reaching action,
appeared in a report prepared by a task force of educators, doctors,
politicians and business people. According to the report, a fourth of the
nation’s 12 infants and toddlers live in poverty. As many as half confront risk
factors that could harm their ability to develop intellectually, physically and
socially. Child immunizations are too low, more children are born into poverty,
more are in substandard care while their parents work and more are being raised
by single parents When taken together, these and other risk factor can lead to
educational and health problems that are much harder and more costly to
reverse.
The crisis beings in the womb with unplanned parenthood.
Women with unplanned pregnancies are less likely to seek pre-natal care. In the
U.S. 80% of teenage pregnancies and 56% of all pregnancies are unplanned. The
problems continue after birth where unplanned pregnancies and unstable
partnerships often go hand in hand. Since 1950, the number of single parent
families had nearly tripled. More than 25 percent of all births today are to unmarried
mothers. As the number of single parent families grows and more women enter the
work force, infants and toddlers are increasingly in the care of people other
than their parents.
Most disturbingly, recent statistics show that American
parents are increasingly neglecting or abusing their children. In only four
years from 1987-1991, the number of children in foster care increased by over
50 percent. Babies under the age of one are the fastest growing category of
children entering foster care. The crisis affects children under the age of
three most severely the report says. Yet, it is this period-from infancy
through preschool years- that sets the stage for a child’s future.
The main focus of the passage is on the plight of
