2 SECTION-I Answers for questions 1 to : D should be the opening sentence of the passage as it refers to misery that struck North Carolina last September. G must follow next as it states what exactly happened. G must be followed by B as it talks about another disaster that followed. A refers to the nature of this disaster and hence must follow B. E mentions the consequences of this disaster. C states how generally the area s brackish estuaries are well mixed and F states how the hurricane affected this. So F must follow C. So the correct sequence is DGBAECF. 1-[d] -[a] 3-[d] -[b] -[a]. From the passage we can decipher that one talks about the inconsistency that exists in life. Everybody craves for certainty. Option [a] does not fit with the later half of the passage which talks of disappointments when you cannot be sure. Option [d] does not fit grammatically. 7. Option [c] is logically appropriate. Options [a] and [d] mean the opposite of what is required to complete the sentence. Option [b] doesn t fit with the context of the sentence. 8. Option [a] best fits the blank. Optimistic brings in a positive feeling which cannot be ascertained here. Options [c] and [d] are irrelevant. 9. Option [d] most logically follows the theme. Option [a] is the opposite of what is required. Options [b] and [c] are irrelevant as they drift from the theme of the given passage. 10. Option [d] fits the blank most appropriately. Options [a], [b] and [c] are irrelevant. 11. Options [a] and [b] are irrelevant. Options [c] and [d] are close. But [d] is the correct option as there is nothing to prove if something is natural. 1. Option [c] best fits the blank as inevitable means invariably occuring or impossible to avoid. It fits the logic best. 13. We are talking of repressive and persecuting passions. Option [b] best fits the blank as unhappiness is the cause of the above. 1. Option [a] best fits the blank, whereas the other options are out of context. 1. Options [a] and [d] are irrelevant. Option [b] does not convey the underlying meaning. 1. Refer to paragraph 1, responsible travel to... local people. EXPLANATORY ANSWERS 17. Refer to paragraph 7. Each area has a carrying capacity and tourists must be admitted upto that capacity. 18. Refer to paragraphs and 3, Traditional or conventional... to mankind. 19. Refer to paragraph, India...for ecotourism. 0. Refer to paragraph 8. There would be economic viability if tourist destinations are preserved for future generations. 1. The BD link is the most crucial. B states how in Athens, these Games have met something deeper and more powerful - they have come up against the reason for being (sentence D).. D should follow statement 1 as it states how flying cheap has become a reality now and is no longer a flight of fantasy. But the CB link is important. C states how a clutch of low-cost no-frills airlines is promising to open the skies to the Indian masses. B cites the instance of one of the first ones. Hence,[a]. 3. Note the AC link. A reason why Greek food is considered remarkably healthy is stated in sentence C. This brings us down to options [b] & [d]. But the DB link is a giveaway.. PALE is the word that can be formed and therefore [a] is the correct choice as it is the synonym. [b] cannot be the answer, [c] and [d] are opposites.. The new word formed is MACE. Mace means a stick or a rod.. There is no error in the given sentence. Options [b], [c] and [d] contain parallel structure error and use sustraining instead of to sustain. 7. If dignity. would be the most appropriate start for the sentence. Option [b] has the unnecessary then. 8. [b] has a subject-verb mismatch. [d] wrongly changes the meaning of the sentence. [a] changes the voice of the sentence. On the outskirt is the correct usage. 9. There is no error in the given sentence. All the options other than [a] use wrong verb-preposition combination. 30. The original sentence is correct and only [c] reproduces it. There is no error of parallel construction. IMS-1--MOCK TEST-1

3 31. The verb in [b] should be could make not could made. 3. May never will be in [c] should be may neverbe. 33. A plural verb were is used for a singular subject a Ripper victim in [b]. 3. The plural of crisis is crises, not crisises. 3. The verb had in [b] should be has. 3. The subject is singular, box, so the verb must be singular, was, instead of were. 37. This sentence has no error. 38. Whether is a homonym of the correct word - weather. 39. They is meant to refer back to one ; since one is singular, they (plural) is incorrect. The correct pronoun is one. 0. Laying means putting in place ; the main idea here is resting, so the correct word is lying. SECTION-II 1. Karuna is Jitu s sister and Jitu is Iqbal s uncle. Therefore, Karuna could be Iqbal s mother or aunt.. Dinesh is Sunita s grandfather and Jitu is Sunita s and Iqbal s uncle. Also, Jitu is Lara s nephew. Therefore, Dinesh and Lara are from the first generation, Jitu and Karuna from the second and Sunita and Iqbal are from the third generation. Therefore, Iqbal and Sunita could be Karuna s children. Dinesh and Lara cannot be Karuna s children. 3. Karuna is Lara s neice since Jitu is Lara s nephew. Therefore, Lara s daughter will be Karuna s cousin.. Dinesh is Sunita s grandfather fi Dinesh is Iqbal s grandfather. Dinesh need not be Jitu s father. Karuna could be Iqbal s mother or aunt. Lara s gender is not known. Hence, [a], [b] and [c] need not be true.. Iqbal and Sunita will be Tina s cousins.. According to the passage, when Danes talk to foreigners about Denmark, they comment on its negative aspects. This implies that no Dane would look at you in the eye and say that Denmark is a great country. The above statement thus is true. 7. Since Danes are themselves modest by nature, they do not talk about Denmark s virtues, that the Danes want others to figure out by themselves the greatness of Denmark cannot be determined from the information given. 8. The statement is probably false. When the Danes talk to foreigners they usually comment on the negative aspects of their country as boasting about their country does not go with their modest nature. Thus complaining about the high taxes does not mean that the Danes are actually unhappy about their taxes. 9. According to the passage Danes never talk about how proud they are to be Danes as they take pride in being modest. So it is not that they are not proud to be Danish - they don t prefer to talk about it. 0. I is a weak argument because it merely gives the statistics of last year and does not give an indication of the widening gap. Again it is the same in argument II and thus again weak. Argument III talks of landline connections going up but does not say why India will not have more mobile phone users by 007. Hence,[d]. 1. Argument I is weak as it does not say how the boarding school is going to help young pupil develop those interest. II is strong because of do not always, as the regulation of the pupil could be institutionalized. III is weak as it is only speaking from a section of many pupils.. I is strong as it tells of the absence of responsibility on the father. II tells about the ill effects due to child care centre options, etc. but does not tell about mother staying at home, and is thus weak. It is the same with III as it speaks from the point of many and not all. 3. I is weak as it talks of a sub-set factories and managers only but does not take China into consideration. II is strong as it argues about unpreparedness for competition. III is weak as it again talks of managers only.. I is weak as it argues by taking only a single country into consideration (Canada). II is not a relative argument because it includes people who commit other crimes. III is also weak as it expresses not with surity but with possibility may.. B is the cause and A is the effect. As some villages are not connected commuting becomes difficult.. The correct option is [d] where statements A and B are effects of some common cause. From both the sentences we can gather that the ministry in broad terms wants to reduce the tax burden on the common man. Thereby both are effects of some specific cause which is not known to us. 3 IMS-1--MOCK TEST-1

4 7. The correct option is [c] where statements A and B are effects of some independent causes. We cannot deduce from just these two statements as to why the grass is green and how the grass can prepare its own food. 8. The correct option is [b] where statement B is the cause and statement A is the effect. Clearly we can identify with the situation and say that since she has been out all day she was feeling tired. 9. The correct option is [a] as the disastrous play is the reason for the disappointment among the audience. 0. The correct option is [a], where statement A is the cause and statement B is the effect. It is because they are poor they have no money to buy food. The conclusion is simple and straightforward. 1. The series is of the following form: The odd man out is 1..
