Directions (1-10): In the following passage there are blanks each of which has been numbered. These numbers are printed below the passage and against every five words are suggested one of which fits the blank appropriately. Find out the appropriate word in each case.
(1)_________ made by a variety of spacecraft over the past few decades suggest that the moon harbors a lot of water ice in (2)________ shadowed craters near the poles, which are some of the coldest locales in the solar system. Siegler and his colleagues studied measurements made by two of these probes: NASA’s (3)________ Lunar Prospector (LP) spacecraft, which (4)________ the moon from January 1998 through July 1999, and the agency’s Lunar Reconnaissance Orbiter (LRO), which is still in operation. The orbiters’ data revealed (5)_________ ice deposits at both poles, as expected. But there was a surprise as well: A large patch of ice (6)________ near each pole, in a spot offset from the true pole by 5.5 degrees. Moreover, these “displaced” deposits are positioned such that a straight line is drawn through the center of the moon (7)________ connect them. Siegler and his team have an explanation for this finding, which they report online in March in the journal Nature: The moon’s (8)________ axis has (9)______ by 5.5 degrees (10) _______ the ages, and the offset ice patches mark the “paleopoles.”
1. (A) Observatories
(B) Observations
(C) Observes
(D) Observation
(E) observed
Answer: Option (B)
Explanation: look at the meaning of the following options:
Observatories: A room or building housing an astronomical telescope or other scientific equipment for the study of natural phenomena.
Observations: The action or process of closely observing or monitoring something or someone.
Observes: Notice or perceive (something) and register it as being significant.
Now, as per the meaning of the passage either ‘observations’ or ‘observation’ is the correct option. Now, the usage of a plural verb ‘suggest’ in the latter part of the sentence shows that the blank should be filled with a plural subject. Hence, ‘observations’ is the correct option.
2. (A) permanently
(B) permanent
(C) transitory
(D) randomly
(E) transiting
Answer: Option (A)
Explanation: Look carefully at the structure of the phrase i.e. ‘shadowed (adjective) + craters (noun)’. So, as per the rules of grammar, the blank should be filled with an adverb. Therefore, ‘permanent’ and ‘transitory’, which are adjectives, cannot be the answer. Now ‘randomly shadowed craters’ does not go with the sense of the passage. Hence ‘permanently’ is the correct option.
3. (A) pioneering
(B) primitive
(C) auxiliary
(D) reserved
(E) reserving
Answer: Option (A)
Explanation: Look at the meaning of the given options
pioneering: Involving new ideas or methods.
primitive: Relating to, denoting, or preserving the character of an early stage in the evolutionary or historical development of something.
auxiliary: Providing supplementary or additional help and support.
reserved: Slow to reveal emotion or opinions. Hence, ‘pioneering’ is the only option that goes with the sense of the passage.
4. (A) rotated
(B) revolves
(C) revolved
(D) circled
(E) rotates
Answer: Option (D)
Explanation: Look at the meaning of given options:
Rotate: To turn or cause something to turn in a circle, around a fixed point.
Revolve: To move or cause something to move around a central point in a well-defined path.
Circled: To move in a circle, often around something.
Now, both ‘revolve’ and ‘circled’ can be the correct option. But the action was done in the past (1998-99 ). Hence, ‘circled’ is the correct option.
5. (A) that
(B) if
(C) whether
(D) few
(E) some
Answer: Option (E)
Explanation: Since the sentence is not reported by a person, hence, it is not in indirect speech. Therefore, ‘that’, ‘if’ and ‘whether’, which are conjunctions used in indirect speech, cannot be the correct answer. Again, ‘few’ cannot be the correct answer. Since it is used with a countable noun and ‘ice deposits’ is uncountable. Hence, ‘some’ is the correct option.
6. (A) existed
(B) appear
(C) exists
(D) exist
(E) appeared
Answer: Option (C)
Explanation: Since the sentence is a universal fact hence ‘present indefinite tense’ should be used. Out of the given options only ‘appear’, ‘exists’ and ‘exist’ can be the correct option. But here, the subject is ‘A large patch of ice’ which is singular hence verb used should also be singular. Hence, ‘exists’ is the correct option.
7. (A) will
(B) would
(C) shall
(D) can
(E) ought to
Answer: Option (B)
Explanation: Though the sentence is in future perspective, hence, ‘will’ should be used, but after a careful reading of the sentence, one could infer that the sentence is in Passive voice. Hence, ‘would’ is the correct option.
Note: Following is the usage of other options:
Will: Used to talk about what is going to happen in the future, especially things that you are certain about or things that are planned.
Shall: Used instead of “will” when the subject is “I” or “we”
Can: Used to denote ‘ability’ and ‘permission’
Ought to: Used to show when it is necessary or would be a good thing to perform the activity referred to by the following verb.
8. (A) rotational
(B) rotating
(C) revolutionary
(D) revolving
(E) revolve
Answer: Option (A)
Explanation: The blank is followed by a noun (axis), hence, blank should be filled with an adjective. Therefore, ‘revolving’ and ‘rotating’, which are verbs, cannot be the correct option. Hence, either ‘rotational’ or ‘revolutionary’ should be the correct option. Now, heavenly bodies ‘Rotate’ on its ‘axis’ and ‘Revolve’ around its ‘orbit’, Hence, ‘rotation’ is the correct option.
9. (A) shifted
(B) drifted
(C) dispersed
(D) veered
(E) shifts
Answer: Option (A)
Explanation: Look at the meanings of the given options:
Shifted: Move or cause to move from one place to another, especially over a small distance.
Drifted: Be carried slowly by a current of air or water.
Dispersed: Distribute or spread over a wide area.
Veered: change direction suddenly. Hence ‘shifted’ is the only option which goes with the meaning of the sentence.
10. (A) with
(B) in
(C) over
(D) along
(E) besides
Answer: Option (C)
Explanation: ‘over the ages’ is correct idiomatic usage.
over the ages: extending a long time in the dimension of time (from some point in time in the very remote past)
