Consider the following statements about Sea floor spreading.1. It is caused by a sinking mantle.2. It is verified by the observation that ocean crust rocks are much younger than the continental rocks.3. The sediments on the ocean floor get unexpectedly very thick due to sea floor spreading.Select the correct answer using the codes below.
Constant eruptions at the crest of oceanic ridges cause the rupture of theoceanic crust and the new lava wedges into it, pushing the oceanic crust on either side. The ocean floorthus spreads, known as sea floor spreading. Sea floor spreading is verified using these phenomena- It wasrealised that all ^ong the mid-oceanic ridges, volcanic eruptions are common and they bring huge amountsof lava to the surface in this area. The sediments on the ocean floor are unexpectedly very thin The age ofthe rocks increases as one moves away from the crest. The ocean crust rocks are much younger than thedeeoT t ri rt'h L thin.

Which of the following places in India host important synagogues religious places of worship for theJews, who have been recently recognized as a minority In Maharashtra?1- Cochin 2. Pune 3. KolkataSelect the correct answer using the codes below.
Background and Justification: The Jews of India waited centuries to build their first synagogues, praying inernporary structures or private houses. The buildings that were eventually built vary greatly in their scalestyle, and visual orientation. Some, particularly those belonging to the Baghdadi Jews basedJrUVlumbalKolkata, and Pune, are grand and built in various Western styles usiqg fine materials and elaborate detailConstructed by the Baghdadi Jewish community who first came from Iraq, Iran, and a handful of other NearEastern countries and settled in India permanently beginning in the 18th century is a Neo-Baroquesynagogue in the Fort section of Mumbai, a Renaissance revival one In central Kolkata and.

In a simple open Keynesian economy, if investment equals savings then the budget deficit should bemet by and equal ^
The identities belowC + I + G + X-MeC + S + TCancelling final consumption expenditure C from both sides we getI + G + X-M5S + TIn other words (I - S) + (G - T) = M - XX2.8)In as), G - T measures by what amount the government expenditure exceeds the tax revenue earned byIt. This IS referred to as budget deficit. cd. neo oyM - X is known as the trade deficit - it measures the excess of import expenditure over the export revenueearned by the economy (M is the outflow from the country, X is the inflow into the country) If there is nogovernment, no foreign trade then G = T=M = X = 0. nereis noHence (2.8) yields I = S (2.9) (2.9) is simply an accounting identity. Out of the GDP, a part is consumed and apart,is saved (from the recipient side of the incomes). On the other hand, from the side of the firms, theaggregate final expenditure received by them (= GDP) must be equal to consumption expenditure andinvestment expenditure. The aggregate of incomes received by the households is equal to the expenditurereceived by the firms because the income method and expenditure method would give us the same figureof GDP. Since consumption expenditure cancels out from both sides, we are left with aggregate savingsequal to the aggregate gross investment expenditure.

The Gondwana system of sediments from India is known to have its counter parts in six differentlandmasses. These landmasses do not include
Option D, Mongolia, is ruled out because these deposits are only found in SouthernHemisphere, apart from being found in India.Learning: Tillite is the sedimentary rock formed out of deposits of glaciers. The Gondawana system ofsediments-from India is known to have its counter parts in six different landmasses of the SouthernHemisphere. At the base the system has thick tillite indicating extensive and prolonged glaciation. Counterparts of this succession gre found in Africa, Falkland Island, Madagascar, Antarctica and Australia besidesIndia. Overall resemblance of the Gondawana type sediments clearly demonstrates that these landmasseshad remarkably similar histories. The glacial tillite provides unambiguous evidence of palaeoclimates andalso of drifting of continents.

What is the rationale and effect of fixing the maximum of GNI per capita at $75,000?1. Contribution of income to human development tends to diminish as incomes rise after a certain limit.2. Putting a cap on Income levels would allow for a more realistic assessment of human developmentwithout which rich countries would dominate the rankings.Which of the above is/are correct?
Income is instrumental to human development, but the contribution diminishes asincomes rise. Also a high income without being translated into other human development outcomes is ofless relevance for human development. Fixing the maximum at $75,000 means that for countries with 6NIper capita greater than $75,000, only the first $75,000 contributes to human development. In this way thehigher income is prevented from dominating the HDI value. Currently we have only 4 countries with GNI pcabove the cap - Liechtenstein, Kuwait, Qatar and Singapore. The projections based on fairly realistic growthrates have shown that by 2018 not more than five countries will exceed the limit.

Consider the following statements.1. Electronic Voting Machines (EVMs) were successfully used on an experimental basis for the first time ingeneral elections of 1998.2. The None of the Above (NOTA) option was employed in the 2014 general elections.3. Verifiable Paper Audit Trail (VVPAT) machines were successfully used for the first time in 2016 Rajasthanassembly elections.Select the correct answer using the codes below.
Justification: Statement 1: EVMs were used on an experimental basis for the firsttime in elections to 16 Assembly constituencies in Madhya Pradesh (5), Rajasthan (5) and Deihi (6) held InNovember, 1998. Earlier attempts had sort of failed.Statement 2: In the 2014 general election, NOTA polled 1.1% of the votes, counting to over 6,000,000. Thespecific symbol for NOTA, a ballot paper with a black cross across it, was introduced on 18 September 2015.statement s; Voter-verified paper audit trail (VVPAT) system was introduced in 8 of 543 pariiamentaryconstituencies as a pilot project in Indian general election, 2014. It was first used in an election in India inSeptembep2013 in Noksen (Assembly Constituency) in Nagaland. Verifiable Paper Audit Trail (VVPAT)machines and next generation EVMs will be used for the first tfrne in Rajasthan in the ensuing assemblyelections (^018). The 'M3'-type electronic voting machines (EVMs), which the Election Commission plans touse, are equipped^with a self-diagnostic system for authentication of genuineness of the machines.

Consider the following statements.1. Mid-Atlantic ridge Is an example of convergent boundary.2. A subduction zone cannot be formed between an Oceanic and a continental plate.3. Transform faults are the planes of separation generally perpendicular to the mid-oceanic ridges.ie correct answer using the codes below.
Statement 1: Divergent Boundaries are formed where new crust is generated as theplates pull ^way frorn each other. Thesites where the plates move away from each other are calledpreading sites. T+ie best-known example of divergent boundaries is the Mid-Atlantic RidgeAt this, the American Platq(s) is/are separated from the Eurasian and African PlatesStatement 2: Where the crust is destroyed as one plate dived under another is called a convergentboundary. The location where sinking of a plate occurs is called a subduction zone. There are three ways inwhich corrvergence can occur. These are: (i) between an oceanic and continentai plate; (ii) between twooceanic plates; and (111) between two continental plates. Statement 3: Transform Boundaries form wherethe crust IS neither produced nor destroyed as the plates slide horizontally past each other. Transformfaults are the planes of separation generally perpendicular to the mid-oceanic ridges. As the eruptions donot take all along the entire crest at the same time, there is a differential movement of a portion of thep ate away from the axis of the earth. Also, the rotation of the earth has its effect on the separated blocksOf the plate portions.
