MCQ->In this question, a column and a statement followed. Read the paragraph carefully and decide on the basis of that column.Moscow officials said that a pair of Russian astronauts cut out the material samples around a spy hole in a Soyuz spacecraft stationed at the International Space Station on Tuesday using knives and chin knives. It was discovered in August, after the last trip of the spacecraft, that the 2-meter pipe airbag on the Soyuz spacecraft was parked at international space. The Rascassasmos Space Agency said that the small but dangerous hole had been found on Earth or in the outer space was to cut the enclosed glue material, to analyze the model of the material and to pull it into a new tapper in that area.Senior astronauts fought and ultimately succeeded in their pursuit. Before this astronaut walk, the spacecraft could only examine the hole within the spacecraft. Unlike the International Space Station, the Soyce shuttle was not designed to repair and hold the spacecraft in the outer space, but did not have any of the handles to hold. The claim was that astronauts had cut the glue around the hole, but failed to collect the sample to analyze Arkal.Select the correct answer from the following A - The claim is entirely correct B - the claim may be correct C - can not determine the claim D - The claim is completely false.....

MCQ-> In the following questions, you have two passages with 5 questions in each passage. Read the passages carefully and choose the best answer top each question out of the four alternatives. A dolphin is an aquatic mammal. Dolphins are extremely intelligent and sociable animals and have their own way to communicate with each other using special sounds. Although they are often mistaken for fis, dolphins are actually mammals. They are members of the Cataca (pronounced se-ayshia) family, which also contains whales and porpoises. One way of telling the difference between a cetacean and a fish is by looking at their tails. You can tell a cetacean because their tail fins (called flukes) are horizontal and move up and down. Fish have vertical tails which move from side to side. A dolphin’s body is designed to help them move quickly and easily through water. On its back is a curved dorsal fin and on each side of the dolphin is a pectoral fin. The bump on a dolphins head is known as the melon. They trap their prey by using their teeth. Dolphins use a type of sonar to detect where objects are around them. This is called echolocation. Echolocation works when a dolphin bounces a high pitched sound off an object and then listens for the echo to come back. It is a very useful way for dolphins to find food and navigate. Dolphins communicate with each other through clicks, squeaks and whistles. They use these special sounds to greet each other and to indicate if they are in distress. Dolphins live in the sea, but they can’t breathe under water. They breathe through a blowhole and have to come up for air every 15 minutes.Cetacea does not include:

MCQ->In this question, a passage is given followed by a statement. Read the passage carefully and judge the statement based on the given passage. Using knives and shears, a pair of Russian spacewalkers on Tuesday cut samples of material around a mysterious hole in a Soyuz spacecraft docked on the International Space Station that a Moscow official suggested could have been deliberately sabotaged. The 2 mm cavity on the Soyuz spaceship docked at the ISS caused an air leak detected in August, two months after the craft’s last voyage. Roscosmos space agency said the aim was to discover whether the small but dangerous hole had been made on Earth or in space, to cut away the insulation covering the hole, take out a sample of the material around it to analyse and put new insulation over the area. Roscosmos chief stated that an investigation had ruled out a manufacturing error. The veteran cosmonauts struggled but eventually succeeded in their mission. Before this spacewalk, astronauts had only been able to examine the hole from inside the spacecraft. What made it especially hard is that the Soyuz spacecraft, unlike the ISS, was not designed to be repaired in spacewalks and has no outside railings for astronauts to hold onto. Statement: The mysterious hole in the Soyuz spacecraft is not due to manufacturing error.Choose the appropriate one from the following options A - The statement is definitely true. B - The statement is probably true. C - The statement cannot be determ ined. D - The statement is definitely false.....

MCQ-> Read the following passage carefully and answer the questions given below it. Certain words/phrases have been printed in bold tohelp you locate them while answering some of the questions. During the last few years, a lot of hype has been heaped on the BRICS (Brazil, Russia, India, China, and South Africa). With their large populations and rapid growth, these countries, so the argument goes, will soon become some of the largest economies in the world and, in the case of China, the largest of all by as early as 2020. But the BRICS, as well as many other emerging-market economieshave recently experienced a sharp economic slowdown. So, is the honeymoon over? Brazil’s GDP grew by only 1% last year, and may not grow by more than 2% this year, with its potential growth barely above 3%. Russia’s economy may grow by barely 2% this year, with potential growth also at around 3%, despite oil prices being around $100 a barrel. India had a couple of years of strong growth recently (11.2% in 2010 and 7.7% in 2011) but slowed to 4% in 2012. China’s economy grew by 10% a year for the last three decades, but slowed to 7.8% last year and risks a hard landing. And South Africa grew by only 2.5% last year and may not grow faster than 2% this year. Many other previously fast-growing emerging-market economies – for example, Turkey, Argentina, Poland, Hungary, and many in Central and Eastern Europe are experiencing a similar slowdown. So, what is ailing the BRICS and other emerging markets? First, most emerging-market economies were overheating in 2010-2011, with growth above potential and inflation rising and exceeding targets. Many of them thus tightened monetary policy in 2011, with consequences for growth in 2012 that have carried over into this year. Second, the idea that emerging-market economies could fully decouple from economic weakness in advanced economies was farfetched : recession in the eurozone, near-recession in the United Kingdom and Japan in 2011-2012, and slow economic growth in the United States were always likely to affect emerging market performance negatively – via trade, financial links, and investor confidence. For example, the ongoing euro zone downturn has hurt Turkey and emergingmarket economies in Central and Eastern Europe, owing to trade links. Third, most BRICS and a few other emerging markets have moved toward a variant of state capitalism. This implies a slowdown in reforms that increase the private sector’s productivity and economic share, together with a greater economic role for state-owned enterprises (and for state-owned banks in the allocation of credit and savings), as well as resource nationalism, trade protectionism, import substitution industrialization policies, and imposition of capital controls. This approach may have worked at earlier stages of development and when the global financial crisis caused private spending to fall; but it is now distorting economic activity and depressing potential growth. Indeed, China’s slowdown reflects an economic model that is, as former Premier Wen Jiabao put it, “unstable, unbalanced, uncoordinated, and unsustainable,” and that now is adversely affecting growth in emerging Asia and in commodity-exporting emerging markets from Asia to Latin America and Africa. The risk that China will experience a hard landing in the next two years may further hurt many emerging economies. Fourth, the commodity super-cycle that helped Brazil, Russia, South Africa, and many other commodity-exporting emerging markets may be over. Indeed, a boom would be difficult to sustain, given China’s slowdown, higher investment in energysaving technologies, less emphasis on capital-and resource-oriented growth models around the world, and the delayed increase in supply that high prices induced. The fifth, and most recent, factor is the US Federal Reserve’s signals that it might end its policy of quantitative easing earlier than expected, and its hints of an even tual exit from zero interest rates. both of which have caused turbulence in emerging economies’ financial markets. Even before the Fed’s signals, emergingmarket equities and commodities had underperformed this year, owing to China’s slowdown. Since then, emerging-market currencies and fixed-income securities (government and corporate bonds) have taken a hit. The era of cheap or zerointerest money that led to a wall of liquidity chasing high yields and assets equities, bonds, currencies, and commodities – in emerging markets is drawing to a close. Finally, while many emerging-market economies tend to run current-account surpluses, a growing number of them – including Turkey, South Africa, Brazil, and India – are running deficits. And these deficits are now being financed in riskier ways: more debt than equity; more short-term debt than longterm debt; more foreign-currency debt than local-currency debt; and more financing from fickle cross-border interbank flows. These countries share other weaknesses as well: excessive fiscal deficits, abovetarget inflation, and stability risk (reflected not only in the recent political turmoil in Brazil and Turkey, but also in South Africa’s labour strife and India’s political and electoral uncertainties). The need to finance the external deficit and to avoid excessive depreciation (and even higher inflation) calls for raising policy rates or keeping them on hold at high levels. But monetary tightening would weaken already-slow growth. Thus, emerging economies with large twin deficits and other macroeconomic fragilities may experience further downward pressure on their financial markets and growth rates. These factors explain why growth in most BRICS and many other emerging markets has slowed sharply. Some factors are cyclical, but others – state capitalism, the risk of a hard landing in China, the end of the commodity supercycle -are more structural. Thus, many emerging markets’ growth rates in the next decade may be lower than in the last – as may the outsize returns that investors realised from these economies’ financial assets (currencies, equities. bonds, and commodities). Of course, some of the better-managed emerging-market economies will continue to experitnce rapid growth and asset outperformance. But many of the BRICS, along with some other emerging economies, may hit a thick wall, with growth and financial markets taking a serious beating.Which of the following statement(s) is/are true as per the given information in the passage ? A. Brazil’s GDP grew by only 1% last year, and is expected to grow by approximately 2% this year. B. China’s economy grew by 10% a year for the last three decades but slowed to 7.8% last year. C.
