Correct Answer : A

The USA shows the minimum variation: none, since it is first in both years.

Rank the four countries in 2007 and 2011 by share, with tied countries on the same rank:

\[ \begin{aligned} \text{USA} &: 1 \to 1,\ \text{change } 0 \\ \text{France} &: 3 \to 2,\ \text{change } 1 \\ \text{Germany} &: 7 \to 3,\ \text{change } 4 \\ \text{UK} &: 4 \to 6,\ \text{change } 2 \end{aligned} \]

In 2007 the UK's 8% is tied with Canada and Greece behind USA, Sweden and France, and in 2011 its 6% is tied with Belgium and Canada behind five countries. The smallest change is the USA's zero.

Correct Answer : B

The lowest percentage increase belongs to Q.

Percentage increase = (2010 runs - 2009 runs) / 2009 runs x 100:

\[ \begin{aligned} P &: 206/802 = 25.7\% \\ Q &: 147/765 = 19.2\% \\ R &: 190/429 = 44.3\% \\ S &: 200/501 = 39.9\% \end{aligned} \]

Q has the smallest increase, both in runs (147) and as a percentage. P has the highest totals and might look slowest-growing at a glance, but its increase is 25.7%. R and S, starting from lower bases, grew fastest.

Correct Answer : E

Correct answer: None of these

The machine sorts alphabetically one position at a time and passes over any word already correctly placed. The six words order as and, Do, on, pet, that, to, so at Step II the first two positions hold “and Do” and the remaining four keep their input order - here “pet to on that”. Only the third option has that tail, but from it Step I alone already yields the given line, and Step II would go on to place “on” third. Since no option can be the input, the answer is none of these.

Correct Answer : B

A flash in the pan is a sudden but temporary success.

The idiom comes from the old flintlock musket: sometimes the powder in the priming pan flashed without firing the main charge, so there was a bright burst and then nothing. A flash in the pan is therefore something that makes a striking start but soon fades, an effort that comes to nothing.

'A spectacular and lasting success' gets the first half right but contradicts the essential idea of not lasting. 'A complete failure' misses the initial brilliance, and 'a well-planned strategy' has no connection with the idiom.

Correct Answer : C

\(\mathrm{FCH_2COOH}\) is the strongest acid of the four.

The halogen withdraws electron density along the chain by the inductive effect, stabilising the carboxylate anion and so making the proton easier to lose. That effect grows with electronegativity, which falls F > Cl > Br > I, so fluoroacetic acid is the strongest \((pK_a \approx 2.6)\) and iodoacetic the weakest \((\approx 3.2)\).

Carbon dioxide is the gas chiefly responsible for global warming. It is not the most powerful greenhouse gas per molecule, but it is released in by far the greatest quantity and persists in the atmosphere for centuries.

Carbon monoxide and nitrogen peroxide are pollutants rather than significant greenhouse gases; nitrous oxide is a greenhouse gas but is present in far smaller amounts.

The craton is the stable interior of a continent, made up of the ancient crystalline basement rock together with the flat-lying sedimentary platform that covers much of it.

A shield is only the part of the craton where the basement is exposed at the surface, so it is a portion of the craton rather than the whole of it.

The three tribes are Parivara, Talwara and Siddi.

The Constitution (Scheduled Tribes) Order (Second Amendment) Bill, 2019, passed by Parliament, amended the list of Scheduled Tribes for Karnataka. It added Parivara and Talawara as synonyms of the Nayaka community, already a Scheduled Tribe, and included the Siddi community, people of African descent living in the Uttara Kannada, Belagavi and Dharwad districts.

The other sets of names are not the communities covered by the Bill.

Among these regions, mortality is highest in the Eastern Mediterranean Region.

The WHO's World Health Statistics report deaths attributable to unsafe water, unsafe sanitation and lack of hygiene per 100 000 population, by WHO region. The highest rates are in the African and South-East Asia Regions, which are not among the options. Of the four regions given, the Eastern Mediterranean Region, which includes countries such as Afghanistan, Pakistan, Somalia, Sudan and Yemen, has the highest rate.

The European, Western Pacific and Americas Regions have much lower rates because most of their populations have safe water and sanitation.
