the ether is injected through a tube directly into a tube directly into
the gallbladder.the one day treatment works only on cholesterol-based
stones.not those composed largely o calcium.however as the clolesterol
stones are by far the most common typefor millions of gallstones
sufferers the treatment should offer a welcome alternative tosurgery
the commonest option in nost hospitals.

K.electronics technology is coming to the rescue of helicopters which can
be grounded or crash in icy conditions the machines are especially
vulnerable to the build up of ice on both their rotors and engine air
intake when operating in cold damp conditions.the problem is 2 fold
ice increases the weight and the build upp makes the aerofoils
less efficient .now at last a detector has been devised which the company
hopes will mean safer flightsand less frequent grounding.unlike most
devices in use at present it can detect the liquid water content of cloud
above freezing level.so the warning is ginven before the potential hazard
is encountered.
39.an electronic device has been invented which will prevent the build
up of ice on helicopter rotors F
40.helicopters are sometimes grounded because in cold damp weather their
engine air intakes and rotors malfuntion owing to the formatrion of ice.
T
41.only one device can at present detect the liquid water content of
cloud above freezing level C
42.in future fewer helicopters will crash or have to grounded T
L.anyone whos has systematically examined faces will have perceived a
prepondreance although not a proliferation of asymmtry.whether or not
the expression is volitinal and self controlled or spontaneous appears
to predict facial asymmetry as does the type of emotion protrayed.positive
emotions are usually displayed symmetrically although a left sided
representation of a negative emotion is more common.posed expressions and
negative emotions are less likely to be symmetrically represented.
43.an angry person is more likely to have a lopsided expression than
someone who is smiling T
44.a deliberately assumed facial expression will always be asymmetrical F
45.an actor is likely to smile symmetrically when acting C
46.more self conscious people are likely to have less asymmetrically
facial expressions than those who are less aware of themselves T
M. human existence is not susceptible of arbitary division between
consciousness and unconsciousness.the conscious world invades and shapes
the activities of the unconscious while many of the great achievements of
humanity's waking hours were wholly or partly inspires bu dreams .even if
it could be argued that dreams precede experience such a dichotomy could
not be drawn as the influence of dreaming on the waking state would remain
unclear but as yet no common vocabulary exists to record the substance
of prenatal dreaming
47.sleep can be a creative state. T
48.it is difficult to tell whether a sleeper is dr3eaming or not C
49. if we knew what babies dream about before they are born we could
show that conscious and unconscious mond influence one another F
50. it is untrue to claim that the conscious and unconscious worlds never
impinge on one another F
New twenty questions

person looks healthier from outside.the number of red blood cells in
the blood increased and this leads to thickness fo the blood as a result
of which blood lacks inside the vessels .the person suffers heart attact.
one possible solution is to remove a litre of blood or to control the
growth of red blood cells.
53.lung disease precedes the disease x T
54.a person who gets heart attack always has disease x F
55.people suffering from disease x look healthier C
56.one litre of blood must be removed to cure this T
O.a starfire engine has been designed to work only for unleaded
petrol.this crossfire engine is designed for both 1500 and `1800 cc
they internally and externally look alike except for the difference
in wheels ----,2000 cc is differentr from the above.two in terms of 3
features --- ----- ---- on the bumber.
57.the engine run only on the leaded petrol F
58.1500 and 1800 cc look alike F
59.apart from cross fire engines they manfacture ---- F
60.internal structure of the 2000cc is same as that of both 1500 and
1800 cc C
P.a weed killer to kill the weeds has been developed.the weed killer
solution has to be applied to the growing tips. it need not to be applied
to all the tips.the solution has to be prepared in a can in one hand
and the plants are taken in the other hand with a glove and are immersed
in the solution if we cannot immerse them in the solution the solution
can be applied to the roots with a brush.it used without care it can
pose danger to other plants.
61.the solutions has to applied to growing leaves
62.to use the weedkiller first take the plants in the cn as then pour the
solution into it.
63.it is sufficient to apply it only to some roots
64.it effects to the other plants.

Hello gupta,
these are the questions given from tcs paper
dont answer all questions.
In reasoning test at the end of each question we indicated
F,T,C
where F represents False
" T " True
" C " cant say.
after this psychmetry test will be there.dont bother about it it is just
formal.they will not consider it.But answer all 150 questions in 30
minutes
All the best
critical reasonig:
G.statistics show that millions of vehicals have beencarried by shuttle
over the past 30 years through alpine tunnels withouty one ever catching
tire.in the alpine tunnels.drivers and passengers sit in theirvhehicals on
the shuttle trains.only one vehical has evercaught fire on the bussy
french motorail equivalent system.this sort of accidents is not possible
in a closed shuttle. assertinos that a vehical fire will lead to
catastophe have no basis. since the resoures exit do detect,control and
extingush a fire and to remove any persons present safely to an adjoning
wagon, leaving any surviving fire facing rapid extinction within a wagan
built to contain fire for 30 minutes. catastrophe seems very unlikely.
25. if a car cauget fire in a rail shuttle, probably none would be killed.
(T)
26.at least one vehical has cauht fire in an alpine tunnel.(f)
27.if a fire started in a wagon, it would be allowed to burn itself out in
30 minutes.(f)
28.if would theoreticaly be possible for a car to cath fire in aclosed
shuttle system.(F)
H)every form of art is protected by copy write,upon the expiration
of whitch the property passes into the public domain and becomes freely
available to any one wishing to exploit it commercialy. the time has come
when all treasures shoud pass to the controled of a trust,and by this made
readily available to anyone on pament of a fee or royality.the income
fromthe works of tagore would alone be enarmous.these who now main
financialbenifit from his genius should make some contribution to the
welfare of the arts in general.
29.tagore's plays are not protected by copyright. F
30.tagore's decendants should be asked to make some contribution to the
arts C
31.instead of buying a ticket , theatregoers should pay a fee to trust for
the benefit of the arts. C
32. More people could go to the theatre if copy rightwere abolished C
I. Hacking is a crime made possible by a relatively new technology,
which one of the reasons it is often poorly understood and reported.
Many computers, but no means all,are now linked togetherin networks which
allow users on one computer to communicate with others on the same
network.If a computer is not networked,no manipulation of its datafrom
another machine is possible.So long as users are authorised, networking
is just a way of making work easier and more productive.Hacking on the
other hand,is the unauthorised use of networks or unauthorised entty
into the computers themselves.Most people do not need to break into the
networks they use,since they are already accredited users.
33. Most hackers are authorised to break into networks F
34. Computers are only vulerable to the unauthorised manipulation of
their data via another computer if they are networked T
35.The main reason why it is relatively easy to break into a computer is
that few people understand the technology. C
36.Hackers do not work fot the firms whose networks they break into. T
J.Although invaders represent a threat to the conservation of flora and
fauna,there are two special cases in which invasion have been deliberately
brought about.One is the desire to control presents by natural predators,
whichmay have to be brought in from other countries.The second is
releasing organisms into the wild(or on to farms,from which they might
escape)that are completely novel,beacause they have been genetically
engineered.There is nothing intrinsically sinister about engineered
organisms,but any novelty must be regarded as a potential invader.
37.Pest control does not threat the conservation of flora and fauna. T
38.Genetically engineered organisms must always be regarded as poten-
tially dangerous. F
39.Natural predators are work harmful than pests.T
40.Genetically engineered organisms escaped from the farm,they will be
pose a threat to wildlife. T
