The history of the modern world is a
record of highly varied activity, of incessant change, and of astonishing
achievement. The lives of men have, during the last few centuries, increasingly
diversified, their powers have greatly multiplied, their powers have greatly
multiplied, their horizon been enormously enlarged. New interests have arisen
in rich profusion to absorb attention and to provoke exertion. New aspirations
and new emotions have come to move the soul of men. Amid all the bewildering phenomena,
interest, in particular, has stood out in clear and growing pre-eminence, has expressed
itself in a multitude of ways and with an emphasis more and more pronounced,
namely, the determination of the race to gain a larger measure of freedom than
it has ever known before, freedom in the life of the intellect and spirit,
freedom in the realm of government and law, freedom in the sphere of economic
and social relationship. A passion that has prevailed so widely, that has transformed
the world so greatly, and is still transforming it, is one that surely merits
study and abundantly rewards it, its operations constitute the very pith and
marrow of modem history.

Not that this passion was unknown to
the long ages that proceeded the modern periods. The ancient Hebrews, the
ancient Greeks and Roman blazed the was leaving behind them a precious heritage
of accomplishments and suggestions and the men who were responsible for the
Renaissance of the fifteenth century and the Reformation of the sixteen century
contributed their imperishable part to this slow and difficult emancipation of
the human race. But it is in modern times the pace and vigour, the scope and
sweep of this liberal movement have so increased unquestionably as to dominate
the age, particularly the last three centuries that have registered great
triumphs of spirit.

What races, according to the author,
have blazed the way of the spirit of freedom?

Question # 103

The year 2006 was the golden
anniversary, or the 50^{th} birthday, of the Dwight D. Eisenhower
National System of Interstate and Defense Highways. This system, usually
referred to as The Interstate Highway System, is a system of freeways named
after the U.S. President who supported it. The system is the largest highway
system in the world, consisting of 46,876 miles (75,440 km) of freeways. The
construction of the interstate highway system is an important part of American
history. It has played a major role in ** preserving** and maintaining the America way of life.

The interstate highway system has
several major functions. One of its major functions is to ** facilitate** the distribution of US good. Because the
intestate passes through many downtown areas, it plays an important role in the

Today, most of the Interstate system
consists of newly constructed highways. The longest section of the Interstate
system runs from Boston, Massachusetts to Seattle, Washington. It covers
3,020.54 miles. The shortest two-digit interstate is from Emery, North Caroline
to Greensboro, North Caroline. It covers only 12.27 miles. All state capitals
except five are served by the system. The five that are not directly served are
Juneau, AK, Dover, DE, Jefferson City, MO, Carson City, NV, and Pierre, SD. The
Interstate Highway System serves almost all major U.S. cities.

EACH Interstate highway is marked
with a red, white, and blue shield with the word “Interstate,” the name of the
state, and the route number. Interstate highways are named with one or
two-digit numbers. North-south highways are ** designated** with odd numbers; east-west highways are
named with even numbers. The north-south Interstate highways begin in the west
with the lowest odd number; the east-west highways begin in the south with the
lowest even numbers. There all mile markers at each mile of the interstate
system, starting at the westernmost or southernmost point on the highway. Every
Interstate highway begins with the number “0”. Interchanges are numbered
according to their location on the highway in relation to mileage; an exit
between milepost 7 and milepost 8 would be designated “Exit 7.” This system
allows drivers estimate the distance to a desired exit, which a road is leading
off the highway. Despite the common acceptance of the numbering system on the
Interstate highways, some states have adopted different numbering systems. For
example, a portion of the Interstate 19 in Arizona is measured in kilometers
instead of miles since the highway goes south to Mexico.

Since the Interstate highways are
freeways-highways that do not have signs and cross streets – they have the
highest speed limits in the nation. Most interstate highways have speed limits
between 65 – 75 miles per hour (105 – 120 kilometers per hour), but some areas
in Texas and Utah have an 80 mile-per-hour (130 kilometer-per-hour) speed
limit.

The federal government primarily
funds interstate highways. However, they are owned and operated by the
individual states or toll authorities in the states. The federal government
generally funds up to 90% of the cost of an Interstate highway, while the
states pay the remainder of the cost.

How does a driver leave an
Interstate highway?

Question # 106

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 its 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 out
that in the near future they might be successful in achieving this feat. They
have, however, acquired the ability in manipulating 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 is 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 disease from
this world.
