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 the same in meaning as he phrase "holding out" as used in the passage?
Educational planning should aim at meeting the educational
needs of the entire population of all age groups. While the traditional
structure of education as a three layer hierarchy from the primary stage to the
university represents the core, we should not overlook the periphery which is
equally important. Under modern conditions, workers need to rewind, or renew their
professor. The retired and the aged have their needs as well. Educational planning,
in their words, should take care of the needs of everyone.
Our structures of education have been built up on the
assumption that there is a terminal point to education. This basic defect has
become all the more harmful today. A UNESCO report, titled “Learning to be”
prepared by Edgar Faure and others in 1973 asserts that the education of
children must prepare the future adult for various forms of self-learning. A viable
education system of the future should consist of modules with different kinds
of functions serving a diversity of constituents. And performance, not the
period of study, should be the basis for credentials. The writing is already on
the wall.
In view of the fact that the significance of a commitment of
lifelong learning and lifetime education is being discussed only in recent
years even in educationally advanced countries, the possibility of the idea
becoming an integral part of educational thinking seems to be a far cry. For,
to move in that direction means much more than some simple rearrangement of the
present organization of education. But a good beginning can be made by
developing Open University programs for older learners of different categories
and introducing extension services in the conventional colleges and schools. Also,
these institutions should learn to cooperate with numerous community
organizations such as libraries, museums, municipal recreational programs,
health services etc.
Q: What is the main thrust of the author?
A great deal of discussion continues as to the real extent
of global environment degradation and its implications. What few people
challenge however is that the renewable natural resources of developing countries
are today subject to stresses of unprecedented magnitude. These pressures are
brought about, in part, by increased population and the quest for an ever
expanding food supply. Because the health, nutrition and general well-being of
the poor majority are directly dependent on the integrity and productivity of
their natural resources, the capability of government to manage them
effectively over the long term becomes of paramount important.
Developing countries are becoming more aware of the ways in
which present and future economic development must built upon a sound and
sustainable natural resource base. Some are looking at our long tradition in
environmental protection and are receptive to U.S. assistance which recognizes
the uniqueness of the social and ecological system in these tropical countries.
Developing countries recognize the need to improve their capability to analyze
issues and their own natural resource management. In February 1981, for
example, AID funded a national Academy of Sciences panel to advise Nepal on its
severe natural resource degradation problems. Some countries such as Senegal,
India, Indonesia and Thailand, are now including conservation concerns in their
economic development planning process.
Because so many governments of developing nations have
recognized the importance of these issues, the need today is not merely one of
raising additional consciousness, but for carefully designed and sharply
focused activities aimed at management regimes that are essential to the
achievement of sustained development.

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.
Which of the following can be inferred between the behavior of orangutans and that of other ape species?
