Answer All the Questions
11. Read the following passage and answer the
questions that follow:
Since
1945, 2051 nuclear tests have been conducted all over the world. Of these, 528
have been in the atmosphere, under water or in space. The rest were underground
tests. The international awareness of the dangers of radioactive effects from
the atmospheric tests came with the 1954 “Bravo” thermonuclear test conducted
by the U.S.
All 23 crewmembers of the Japanese fishing boat named “Lucky Dragon” that was
fishing about 160 km away from the test location, were irradiated. Several fell
sick and died, creating anger in the minds of the people.
The
effect of atmospheric testing were both local and global. Local effects in
regions near testing sites led to relatively large doses of irradiation. For
example, in 1996, the U.S National Cancer Institute estimated that about 10,000
to 75,000 U.S citizens would be affected with thyroid cancer just from iodine –
13 from atmospheric tests. About 10,000 to 40,000 inhabitants of the area
adjacent to the testing site in Kazakhstan
were exposed to an average dose of 160 rods.
In
response to wide spread public concern about the health affects of radioactive
fall out from atmospheric testing a large number of countries signed the
Limited Test Ban Treaty in 1963. The Treaty prohibited all but underground
nuclear tests. Since then most nuclear tests have been conducted underground.
Nuclear establishments the world over have tried to convince their citizens and
others that this possessed no risks top their health. Even from the limited amount
of data that is available, it is clear that this not true.
They hide
their truths regarding the data on health and environment effects of nuclear
weapons testing. Nuclear weapons are secretive about every thing. But the,
absence of such information led to ignorance of the terrific danger involved in
nuclear testing.
In the
case of underground testing, there are further problems. Scientific models for
predicting the spread of radioactive contamination are at their early stages.
The observed rate of plutonium migration, for example, is much larger than what
has been previously predicted. Under such circumstances, it is best to adopt
the cautionary principle that can be reasonably expected and apply appropriate
remedies, for the good of one and all.
(i) Read the
text and say whether the statements are True or False:
(a) Nuclear tests, even when conducted underground,
post risks to our health.
(b) The ‘Bravo’ nuclear test did not prove to be
harmful.
(c) The Limited Test Ban Treaty was signed by a small
number of countries.
(d) The ‘Lucky Dragon’ incident caused the death of 22
members of a Japanese fishing crew.
(ii) Choose the appropriate meaning of words as they
are used in the text.
(A)
Afflicted
(1)
affected (2) died (3) felt sickened (4)
excited
(B)
Estimated
(1)
Calculated (2) speculated (3) found out (4) finished
(C)
Concern
(1)
consideration (2) anxiety (3) industry (4) related
(D)
Predicting
(1)
warming (2) forecasting (3) considering
(4) editing
(or)
(iii) Read the following passage and make notes:
Matter may exist as a solid, or gas
depending on its energy. Gases and vapors are high-energy states of matter;
they flow to take the shape and to occupy the total volume of any container.
When gas loses sufficient energy (in the form of heat or by doing work) it is
considered to be a liquid. Liquids are able to flow, but they are virtually
incompressible. Matter that flows (that is, gas or liquid) is called a fluid.
Liquid molecules are able to move and they flow past each other, but their
motion is much slower than that of gases.
Solids are the lowest energy states of
matter. The usually possess rigid structures, they do not flow and they are
relatively difficult to compress. The atoms in a solid cannot move from one
form to another, but they do vibrate about fixed positions in the structure.
These vibrations are due to thermal energy.
When a solid is heated, the magnitude of
these thermal vibrations j increases until they ‘shake apart’ the solid
structure and the solid melts, becoming liquid. If heat is applied to the
liquid, molecules increase their energy, and evidently have sufficient to
escape through the liquid surface, where they escape.
Some molecules escape from a liquid even at
temperatures below the boiling point, because one molecule may obtain energy
from several others, so that its energy is sufficient to enable it to escape
through the surface. This process is called evaporation, and since it leaves
the other molecules with less average energy, the remaining liquid is cooled.
Read
the following passage and summarise to one third of its size:
Nature is
our mother, She offers us all facilities to lead a comfortable and peaceful
life. She brings us rain. She feeds the human beings who are her children. The
plants, trees, brushes and the grains we grow all belong to nature. Yet man is
not grateful to nature. He pollutes the surroundings and brings destruction to
himself.
Environmental
pollution may be of three kinds. They are air pollution, water pollution and noise
pollution. Air pollution is caused by factories which emerge smoke and fumes.
They mix with the pure air and pollute it. Air pollution is also caused by
fumes from the exhaust pipes of vehicles. It is also caused by all kinds of
refuse such as dust bin refuse, lavatory refuse and washing up refuse. When we
breathe and pollute air, our lungs are affected by diseases.
Water pollution is contaminating water
resources. Factory wastes and gutter water are allowed to flow into rivers.
These waste also get collected in ponds. They pollute the surrounding.
Contaminated water causes many diseases. Cholera is the first among them,
Stagnant water breeds mosquitoes, it results in malaria.
Noise pollution is caused by vehicles
and the horn. Some factories also disturb the peaceful atmosphere around. Loud
speakers are the worst pollutants in this regard. They spoil the entire
atmosphere.
Man cuts and fells trees without any
limit. This causes imbalance on the surface of the earth. This results in lack
of rain and soil erosion. We must protect trees. Let us keep our surroundings
clean and lead a healthy and happier life.

Represent
the following by means of a flow chart
Silver
occurs in the ores of several metals. The froth process of extracting silver
accounts for about 75 percent of silver recovered. Here the ore is ground to
powder, placed in large vats containing water suspension of froth agents and
thoroughly agitated by jets of air. Depending on the agent used either the
silver bearing ore or the gangue adhering to the bubbles of the froth is
skimmed off and washed. The final refining is done using Electrolysis.
Represent this process by means of a flow chart.
