---------------------------------------
1) Here is the structure declaration of a doubly
linked list
struct dlink {int nodeid;
struct dlink *next;
struct dlink *prev;
} dlink_t;
A pointer of the head of the linked list is maintained
as a global variable,
whose definition is
dlink_t *head;
The funtion remove_element(dlink_t *rp), needs to
remove the node pointed to
the rp and adjust the head.
The first node's prev and the last node's next are
NULL.
remove_element(dlink_t *rp)
{rp->prev->next = rp->next;
rp->next->prev = rp->prev;
if( head == rp)
head = rp->next;
Which of the following statement is true about the
function remove_element

list
c) It sets the head of the list correctly
D) It works in all cases
Answer :B
2) Consider the following function written in c:
#define NULL 0
char *
index(sp,c)
register char *sp,c;
{do {if(*sp == c)
return (sp);
} while (*sp++);
return NULL;
}
The first argument sp, is a pointer to a C string. The
second
argument, c, is a character. This function scarches
for the character
c, in the string. If it is found a pointer to that
location is returned
else NULL is returned.

investment in India was transforming the car industry and warned
that jobs were under threat from japanese competition. they stated
that increasing competition would be coupled with an in evitable downturn
if the car market and the recent rise in interest rates which had already
hit demand.

in the future (False)
6. mangers told workers that japanese workers are taking jobs away from
Indian workers in the car industry.

C. Researchers in Mumbai have found that certain types of gallstones
can be dissolved by injecting them with a gasoline additive in the form
of ether 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 on calcium However as the cholesterol
stones are by far the most common type for millions of gallstones sufferers
the treatment should offer a welcome alternative to surgery the commonest
option in most hospitals.

talking to his baby.
13. most working wives do not expect their husbands to share chores
equally (True)
14. the average wife has half as much free time at weekends as her
husband F.
15. some women collude in the unequal distribution of house hold work
because gthey want to retain control C.
16. 39% of all men with working wives do the cooking and aall the cleaning F.
E. Confucius said that to know the future we have to understand
the pasthis time transport communications and scientific knowledge
wireless developed thatn they are today news took weeks to travel
where as today satellite links connect the continents virtually
instantaneously but our technological advances in the field of
communications seem not to have improved our capacity to understand
one another.
17. in confucius day people were more intelligent C.
18. we understand each other better now than in confucius time because

G. Statistics show that millions of vehicles have been carried by
shuttle over the pas 30 years through alpine tunnels withouty one ever
catching tire in the alpine tunnels drivers and passengers sit in their
vehicles on the shuttle trains . Only one vehicle has evercaught fire on
the bussy french motorrail equivalent system . This sort of accidents is
not possible in a closed shuttle. Assertinos that a vehicle fire will lead to
catastophe have no basis. Since the resoures exit do detect, control and
extinguish a fire and to remove any persons present safely to an adjoining
wagon, leaving any surviving fire facing rapid extinction with a wagon built
to contain fire for 30 minutes . Catastrophe seems very unlikely.

shuttle system F.
H. Every form of art is protected by copy write upon the expiration
of which the property passes into the public domain and becomes freely
available to any one wishing to exploit it commercially the time has come
when all treasures should pass to the controlled of a trust, and by this

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 together in 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 data from
another machine is possible. So long as users are authorised, networking is
just a way of makung work easier and more productive. Hacking on the other
hand, is the unauthorisexd use of networks or unauthorised entry into the
computers themselves. Most people do not need to break into the networks
they use since they aare 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 (True)
35. the main reason why it is relatively easy to break into a computer is
that few ppeople understand the technology C.
36. hackers do not work for the firms whose networks they break into.
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,
which may have to be brought n from other countries. The second is
releasing organisms into the wild that are completely novel, because 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 (True)
38. genetically engineered organisms must always be regarded as
potentially dangerous (False).
39. natural predators are work harmful than pests (True)
40. genetically engineered organisms escaped from the farm they will be
pose a threat to wildlife (True)
K. Electronis technology is coming to the rescue of helicopters which can
be grounded or crash in icy conditions the kacnines 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 buld up 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 given before the potential hazard is encountered.
41. an electronic device has been invented which will prevent the build up
of ice on helicopter rotors(False).
42. helicopters are sometimes grounded because in cold damp weather their
engine air intakes and rotors malfunction owing to the formation of ice (True)
43. only one device can at present detect the liquid water content of cloud
above freezing level C.
44. in futur fewer helicopters will crash or have to grounded (True)
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 assymetry as does the type of emotion protrayed posistive
motions 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.
45. an angry person is more likely to have a lopsided expression than
someone who is smiling (True).
46. a deliberately assumed facial expression will always be
asymmetrical (False)
47. an actor is likely to smile symmetrically when acting C.
48. more self conscious people are likely to have less asymmetrically
facial expressions than those who are less aware of themselves (True)
M. Human existence is not susceptible of arbitrary divsion 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 dreawn as the influence of dreaming on the waking state would
reemain unclear but as yet no common vocabulary exists to record the
substance of prenatal dreaming.
49. sleep can be a creative state (True)
50. it is difficult to tell whether a sleeper is dreaming or not C.
51. if we knew what babies dream about before they are born we could
show that conscious and unconscious mond influence one another (False)
52. it is untrue to claim that the conscious and unconscious worlds never
impinge on one another (False).
N. Disease Xsucceeds lung disease it may also occur healthy persons the
person looks healthier from outside the number of red blood cells in the
blood increased and this leads to thickness of the blood as a result of
which blood lacks inside the vessels the person suffers heart attack One
possible solution is to remove a litre of blood or to control the growth of
red blood cells.
53. lung idsease precedes the disease X (True)
54. a person whogets heart attack always has disease X (False).
55. people suffering from disease X look healthier C.
56. one litre of blood must be removed to cure this (True)
O. A starfire engine has been designed to work only for unleaded petrol
this crossfire engine is designed for both 1500 and 1800cc they internally
and externally look alike except for the difference in wheels . 2000cc is
different from the above two i;n terms of 3 features on the bumper.
57. the engine run only on the leaded petrol (False).
58. 1500 and 1800cc look alike (False).
59. apart from cross fire engines they manufacture --- False.
60. internal structure of the 2000cc is same as that of both 1500 and
1800cc C.
P. A weed killer to kill the weeds has been developed the week killer
solution has to be applied to the growing tips it need not be appplied 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 be applied to growing leaves False.
62. to use the weedkiller first take the plants in the can and then pour the
solution into it .
63. it is sufficient to apply it only to some roots .
64. it effects to the other plants.
