- Mark the correct option for blank _(A)_.
- desecrate
- impious
- inflict
- perpetrating
- None of the above
Correct option is : C
Explanation:
Option A “desecrate” means ‘treat a sacred place or thing with violent disrespect’ and can be ruled out as it makes the sentence incoherent.
Option B “impious” means ‘non-pious’ and can be eliminated as it is not related to the context of the passage.
Option D “perpetrating” means ‘to commit’ and though it seems to be in sync with the context, its usage makes the sentence grammatically incorrect. Rather ‘perpetrate’ should be used.
Option C “inflict” means ‘cause something unpleasant or painful by someone or something’ and it aptly fits the context and makes the sentence a meaningful one.
- Mark the correct option for blank _(B)_.
- mitigate
- exacerbate
- alleviate
- effectuate
- None of the above
Correct option is : B
Explanation:
Options A and C “mitigate” and “alleviate” mean ‘make something bad less severe’ and can be eliminated as they have positive connotation and contradict the sentence.
Option D can be ruled out as “effectuate” means ‘put into force or operation’ and is vague in the context of the sentence.
Option B “exacerbate” means ‘make a problem, bad situation, or negative feeling worse’ and is apt as it fits in the blank perfectly. It rightly points at the fact that the social media platforms are worsening the mindset of young people.

- consternate
- poise
- concern
Correct option is : D
Explanation:
Option A “bridle” means ‘show one’s resentment or anger’ can be eliminated as its usage renders the sentence incoherent.
Option B “consternate” means ‘to fill someone with anxiety’ and can be eliminated as it makes the sentence grammatically incorrect. Rather, ‘consternation’ should be used.
Option C “poise” means ‘graceful and elegant bearing in a person’ and can be eliminated as it does not lend any meaning to the sentence and is contextual misfit.
Option D “concern” means ‘make someone anxious or worried’ and here it aptly shows that the politicians, doctors, parents were anxious about the wellbeing of young people.
- Mark the correct option for blank _(D)_.
- reinforcing
- ebbing
- augment
- accentuate
- None of the above
Correct option is : A
Explanation:
The sentence as a whole talks about propagating negative thoughts among youngsters. Thus, the word to be used in the blank should indicate strengthening these thoughts among youngsters.
Option A “reinforcing” means ‘to strengthen and support’ and conforms itself to the explanation above.
Option B “ebbing” means ‘gradually decrease in terms of an emotion or quality’ and can be eliminated as it is contradictory to the meaning expressed in the passage.
Options C and D “augment” and “accentuate” mean ‘making something greater by adding to it or noticeable’ and are not usually used with “feelings”.
- Mark the correct option for blank _(E)_.
- legitimately
- outlandish
- unfairly
- impartially
- None of the above
Correct option is : C
Explanation:
The sentence hints at various complex reasons for which the social media cannot be held responsible for governing the mental wellbeing of young people.
Option C “unfairly” means ‘in a manner that is not in accordance with the principles of equality and justice’ and aptly fits the context and makes the sentence a meaningful one.
Options A and D “legitimately” and “impartially” mean ‘justly’ and can be ruled out as make the sentence logically incorrect as they have positive connotation.
Option B “outlandish” means ‘looking or sounding bizarre or unfamiliar’ and can be eliminated as it is nowhere related to the context of the passage.

The layer of ozone helps ___ A ___ the harmful ultraviolet rays away from entering the Earth’s atmosphere. Ozone layer depletion over the years has ___ B ___ in ozone hole formation through which harmful radiations can now enter the atmosphere. Ozone layer depletion has many ___ C ___ effects including cancer risks. These wavelengths can harm plants and animals and also cause skin cancer, sunburn, and cataracts in humans. The problem is very ___ D ___ indeed and has rightly generated global concern. These concerns led to the ___ E ___ of the Montreal Protocol in the year 1987. This protocol bans the production of ozone-depleting chemicals like CFCs and halons. Ozone depletion refers to a steady ___ F ___ in the total amount of ozone present in the Earth’s atmosphere or the ozone layer. It can also be described as a much larger decrease in stratospheric ozone around the polar regions of the Earth. The second phenomenon is termed as the ozone hole. In addition to these stratospheric events, there are also springtime polar tropospheric ozone depletion events. __________ G __________. These compounds enter the stratosphere after being emitted at the surface where these compounds release halogen atoms by a process called photo dissociation. __________ H __________ . The main cause of ozone layer depletion is the indiscriminate use of CFCs, which are chlorine-based substances. These are widely used in several manufacturing plants, refrigerants and aerosols. __________ I __________. Just one atom of chlorine can destroy around 100, 000 molecules of ozone. Wind blows the CFCs up into the stratosphere. Ozone molecules are already unstable. The chlorine atoms in the CFCs react with the ozone molecules, which break down resulting in the formation of an oxygen molecule and a single free-floating oxygen atom. __________ J __________. However, chlorine in other places such as swimming pools does not pose any danger.

Taken out of context, Chagnon might have been (a) ……his own experience studying the Yanomamö people. He faced a monumental task in the South American fieldwork he began in 1964. The Yanomamö language was (b) ……rich, the conditions dangerous.
Yet in studying the Yanomamö, Chagnon elected to conduct not only traditional ethnographic research, but also complex quantitative research. Besides bringing in a shotgun to deal with predators, Chagnon also (c) …… solarpowered computers to his remote research site when they became available.
But Chagnon, in that February 2009 email, wasn’t talking about his own work. He was advising me about mine.
I was trying, as a historian of science, to understand the culture in which Chagnon lived: academic anthropology. Specifically, I was trying to figure out why the American Anthropological Association had put Chagnon on trial from 2001 to 2002 over charges made by the self-styled “anthropological journalist” Patrick Tierney.
In the email he signed “Shaki” — the name the Yanomamö had given him, translating roughly to “pesky bee” — I don’t think Chagnon was suggesting he found me unqualified or potentially lacking in fortitude. I think he was (d) ……acknowledging the challenges I faced.
Much had happened before and after Tierney had first publicly accused Chagnon and the late geneticist James Neel of high crimes and misdemeanors in a New Yorker article published in October 2000. That article (e) ……the book that would emerge soon after, Darkness in El Dorado: How Scientists and Journalists Devastated the Amazon (Norton).

Direction(31 – 40): In the passage given below there are 10 words given in bold and each of these words is represented by a letter. For each word four alternative words are given as options A, B, C and D. You have to find which word among the options best replaces the already given word. Mark E (No change required) as your answer if the word given in bold is already correct both grammatically and contextually.
A (a) everlasting challenge facing all of the world’s countries, regardless of their level of economic development, is achieving financial stability, economic growth, and higher living standards. There are many different paths that can be taken to achieve these objectives, and every country’s path will be different given the distinctive nature of national economies and political systems. The (b) ingredient contributing to China’s high growth rate over the past two decades have, for example, been very different from those that have contributed to high growth in countries as (c) varied as Malaysia and Malta.
Yet, based on experiences throughout the world, several basic principles seem to (d) downgrade greater prosperity. These include investment (particularly foreign direct investment), the spread of technology, strong institutions, sound macroeconomic policies, an educated workforce, and the existence of a market economy. Furthermore, a common (e) denominator which appears to link nearly all high-growth countries together is their participation in, and integration with, the global economy.
There is (f) primary evidence, from countries of different sizes and different regions, that as countries “globalize” their citizens benefit, in the form of access to a wider variety of goods and services, lower prices, more and better-paying jobs, improved health, and higher overall living standards. It is probably no mere (g) obvious that over the past 20 years, as a number of countries have become more open to global economic forces, the percentage of the developing world living in extreme poverty —defined as living on less than $1 per day—has been cut in half.
As much as has been achieved in connection with globalization, there is much more to be done. Regional disparities (h) pursue: while poverty fell in East and South Asia, it actually rose in sub-Saharan Africa. The UN’s Human Development Report notes there are still around 1 billion people (i) living on less than $1 per day—with 2.6 billion living on less than $2 per day. Proponents of globalization argue that this is not because of too much globalization, but rather too little. And the biggest (j) security to continuing to raise living standards throughout the world is not that globalization will succeed but that it will fail. It is the people of developing economies who have the greatest need for globalization, as it provides them with the opportunities that come with being part of the world economy.

Directions: In the following passage, some of the words have been made bold, each of which is preceded by a letter. Find the suitable word from the options given below that could replace the bold word so as to make the paragraph meaningful.
After years of ___ a ___ disputed over whether Pluto is a planet, in 2006 the International Astronomical Union (IAU) voted to remove Pluto’s planetary status. Now some researchers are ___ b ___ validating this decision, citing the manner in which scientific tradition has dealt with the taxonomy of planets. The IAU, in 2006, designated Pluto a ‘dwarf planet’ along with Ceres in the asteroid belt and Xena, an object in the Kuiper belt, which is an icy ring of frozen objects that circle the solar system beyond Neptune’s orbit. It was a bid to overcome sentiment and go by scientific ___ c ___ reflection . The meeting defined three conditions for a celestial object to be called a planet: one, it must orbit the Sun; two, it should be massive enough to acquire an approximately spherical shape; three, it has to ‘clear its orbit’, that is, be the object that ___ d ___ excerpts the maximum gravitational pull within its orbit. Owing to this third property, if an object ventures close to a planet’s orbit, it will either collide with it and be accreted, or be ejected out. However, Pluto is affected ___ e ___ at Neptune’s gravity. It also shares its orbit with the frozen objects in the Kuiper belt. Based on this, the IAU deemed that Pluto did not ‘clear its orbit’. Dwarf planets, on the other hand, need only satisfy the first two conditions.
This rationale has been questioned by Philip Metzger, a planetary physicist who has worked with the U.S. National Aeronautics and Space Administration, and others who have studied the history of classifying planets and come up with several ___ f ___ abnormal to the third rule. In a paper published in the journal Icarus, they point out that the only work in history that used this rule to classify planets was an article by William Herschel in 1802. They also argue that this work was based on reasoning and observations that have ___ g ___ because been disproved. However, the last argument does not build up a strong enough case to give up what is, in fact, a sensible rule. Physics has many examples where an idea was once ___ h ___ jeopardized for being incorrect, and much later emerged in a different form and gained acceptance — the concept of photons, for instance. And then again, if Pluto were to be re-designated a planet, many more complications would ___ i ___ dwell . For one thing, Charon, Pluto’s moon, is much too large to be called a satellite. Judging by this, the Charon-Pluto system should then rightly be called a binary planet system. This would then lead to classifying several other sets of bodies as binary planets. Recent research shows that both the Kuiper Belt and the Oort cloud, a shell of objects that surrounds the entire solar system far beyond the Kuiper belt, contain objects that can then be called planets, thereby complicating the issue. Denying planetary status to Pluto is then nothing less than a sweep of Occam’s razor, and Pluto remains a dwarf planet, ___ j ___ all an exceptional one.
