52. (c) If it would have been 'security' then it would have been'provided' in the statement not 'subjected'. Exercise doesnot fit. Violation (to breech) is also out of place. Use of'physical' in statement indicates 'violence'. It fits bestin the blank.

53. (c) War is a negative word and it is synonym with massdestruction, death hence certainly has grimconsequences. Happy, Pleasing, exciting all havepositive sense; so can not be linked with war.

54. (b) 'With' is used for 'contentment'. All other options arenot valid and do not have any sense.

55. (d) 'Disgrace to' is perfect as per Standard English Usage.'for' can be used with disgrace as -'His behaviour is a disgrace for all the love showeredby society to his acts.' In this type of question it isvery important to read and reread the sentence to getthe true sense of the situation described in thestatement.

56. (b) ‘Glean’ means ‘to gather ears of corn left’.57. (d) ‘Tactile’ means ‘connecting wiht your sense of touch’.58. (c) Usurp means to seize prower or position of somebody

else without right.59. (b) The word drowsy means half-asleep or sleepy.60. (a) The author talks about the leisure and peace he was

experiencing.61. (d) The author mentions "In a moment the sole porter

emerged from his midday nap".62. (b) The author mentions a reference to the porter by

"operated a signal that clanked noisily into position".63. (c) The word placid means pleasantly calm or peaceful;

unruffled; tranquil; serenely quiet or undisturbed.64. (a) '….. why she wants to see him' is the correct option.65. (c) Here, though everybody is plural the word 'who' is

singular and the verb 'has' must be in consistency with'who'. Also, the sentence is describing an ongoing act,thus tense should be present. These rules out 'have'and 'had' respectively. Hence, 'has finished' is mostappropriate, option (c).

66. (b) This statement provides a hypothetical statement. Thisis best conveyed through the word 'could' suggestingthe willingness to sing but the incapacity to do thesame. Hence, option (b).

67. (c) The sentence sounds grammatically incorrect as 'haveseen him' should not be followed by the adverb 'last'.Use of has/have twice in a sentence is unnecessary.Hence, the most appropriate part is '.. Since I saw himlast'. Option (c).

68. (b) When stating a fact, we need not use presentcontinuous 'is having'. Rather, the sentence shouldhave its verb in the form of simple past. Thus, myneighbour has two cars is correct. Option (b).

69. (b) Flute being a musical instrument it can only be 'played'.Recitation is mostly of a piece of article, poem or extractof a book. Recital is also not compatible with flute.Hence, option (b).

70. (b) Try should be followed by 'to make….'. Also, make himto understand is wrong usage for the unnecessary useof to twice. Hence, option (b).

71. (d) As are has been used in the first part of the sentence,the negating second part must have a compatiblenegative word which is obviously 'aren't. hence, option(d) as no improvement is required.

72. (a) A basic grammar rule requires not to follow 'to' afterusing told as it already implies said to. Rest everythingis correct making option (a) the correct choice.

73. (c) Unless means if not and it cannot follow a negativestatement (double negative). Hence, do not work hardshould be replaced with work hard. Thus option (c) isthe answer.

74. (b) 'Deferential' means behaviour that shows respect.75. (d) ‘Felicitous’ means very suitable or giving a good result.76. (d) ‘Absolve’ means to state officially that someone is not

guilty.77. (b) They sit by the window and watch the traffic.78. (d) I started early for the station lest I should miss the
