CAT Exam 2015 preparation 4

Fossil-fuel companies have lobbied hard – and often successfully – against effective climate policies. But a recent report by the environmental research group CDP revealed that at least 29 major companies, including five major oil producers, are basing their internal planning on the assumption that such policies – specifically, a government-mandated carbon price – will be a reality as soon as 2020. The question now is whether oil-producing countries’ governments and citizens share this expectation. World leaders are ostensibly committed to keeping the increase in average global temperature below 2°C relative to pre-industrial levels – the threshold beyond which the most catastrophic effects of global warming would be triggered. Indeed, they endorsed the limit at the 2009 Copenhagen Climate Change Conference, and again in Cancún the following year.

In the light of the above passage, which of the following is the most relevant question that the author ought to answer?

OPTIONS
	1)	Why does the success of fossil fuel companies’ planning depend on the expectations of oil-producing countries’ governments and their citizens’?
	2)	Will the oil producers’ lobby divest funds from fossil fuels?
	3)	What could be a reason behind the global leaders’ avowed commitment to keeping the increase in average global temperature below 2°C relative to pre-industrial levels?
	4)	Is the report of the environmental research group CDP credibl       John is working on an electronic LED board that has 480 LEDs numbered 1 - 480 and placed in ascending order on the board. He programs the board such that all the LEDs are initially switched off. At the end of one second, all the LEDs are switched on and at the end of two seconds, all the LEDs at even places invert their logic state i.e. they get switched off if they are on and get switched on if they are off. After three seconds, all the LEDs numbered 3, 6, 9, … invert their logic state. This pattern continues at the end of each subsequent second. How many LEDs are on just after 3 minutes and 45 seconds have passed? OPTIONS     1) 169   2) 231   3) 249   4) 311

Reviews of Moto G (2nd Gen) new

Now the new  Moto G is already released ,people who had high hopes from Xiaomi Mi3 remain short lived as now Xiaomi maker had closed for the time being and they are focusing on Redmi 1s,which is a low range phone but it's specification are worth while to go for.But again now Motorola gave another surprise by releasing at right time when xiaomi mi3 stopped.So I am giving the best of reviews for all the people who were dissapointed with xiaomi mi3 but waiting to go for Moto G second gen.These review will clear there mind whether to go for or not.




















 



Review 1
With Xiaomi phones not made available for general public with their show off flash sales, I decided to purchase the Moto G(2nd gen).
This handset from the time of launch is still readily available on flipkart :)

I liked the handset look, feel and overall aspects. The Stereo speakers, Camera and additional storage are the biggest upgrades over the previous phones.

The only con in this phone is the very average battery life. If one is a regular user of the phone for browsing, whatsapp, etc several times a day I feel the battery will drain out in about 8-10 hours.

Overall very much satisfied with this phone for a price of Rs 12,999/- and one can buy on demand and not wait for your lucky chance every Tuesday.

The product is awesome and timely delivery of flipkart was WOW.

I got product properly. Mobile is working Superb.

I must say the right time to get the Moto G2. Previous was 5MP. Now its 8MP.

Micro SD slot was added features and experience of the two speaker makes a value to the phone.

In this range, its an best option. Bad thing i may face future is of inbuilt battery.Normally in all smartphones after some time of use, Phone gets hanged, only one way to bring the phone back in action is to remove the battery and place it back and switch it on. Here if the phone gets hanged, you have to find a service center or have to wait till the battery get empty.

In overall, 7/10, Dynamic 8/10, Camera (in this range) 8/10, Processing speed 8/10


Review 3
Hi friends I have just received my new moto g 2nd generation phone its good to use. The look is awesome 5 inch display is looking great. I was trying to buy Mi3 but couldn't get it but now I am happy with this very much. I guarantee you will be really happy with this product even I had double thoughts but now I feel moto is safer and guaranteed phone better go for it. 


Review 4-
previously used Samsung galaxy grand though there were minimal problems I faced with it when I 1st saw this phone specs I just fixed my mind blindly to go up with this mobile.. seriously satisfied with the every aspect of mobile!!
felt like there would have been a better battery performance not 2070mah though anything more than that would do the thing actually.
but for the price you pay this is the best product anyone could get..no lags, no issues and no complaints just go for it!! in love with android!!
thank uu moto :))

The last sentence from the paragraph has been deleted. Choose the option that best completes the paragraph.

While the new exhibition focuses on Gauguin’s prints, ceramics, and woodcuts, his color paintings should not be overlooked, because Gauguin’s use of color is extraordinary. The fantastic, perfervid Upa Upa (The Fire Dance; 1891), along with Words of the Devil (1892), is reminiscent of Henri Rousseau’s vivid jungle surrealism. To gaze into its lurid, fiery display is to feel as if you were wading into a closed cultic rite. Gauguin could paint a still life like Cézanne and a pointillist gouache like Seurat. He is not often thought of as a great colorist, and while he may not have been Matisse, “Metamorphoses” illustrates that he may have been just as talented. ________________.

OPTIONS
	1)	One can only wonder what one would find when one explores the lesser known aspects of his oeuvre.
	2)	Several of his paintings borrow poses from a sculptured frieze found at the Borobudur Buddhist temple in Indonesia.
	3)	This makes the fact that Gauguin lacked formal artistic training, all the more remarkable.
	4)	In Mata Mua, the light and dark greens, squash yellows, bell-pepper oranges, tomato reds, and eggplant purples are a feast for the eyes.         If a, b, c, d are distinct real numbers such that a and b are the roots of the equation x2 − 3cx − 8d = 0 while c and d are the roots of the equation x2 − 3ax − 8b = 0, what is the value of a + b + c + d? OPTIONS     1) – 48   2) 32   3) 96   4) – 48 or 96   5) – 48 or 32

In Bangalore, my home, investment is pouring into a city at the forefront of the Indian economy’s transformation – home to companies like Infosys and Wipro, and named by Forbes Magazine as one of the “Fastest Growing Cities of the Next Decade.” But, as Bangalore’s citizens prepare to go to the polls in state elections, their concerns are not merely economic. The city’s financial success stories mask a darker reality – quality of life for many city-dwellers has deteriorated over recent years. The movement of the rural poor to large cities is one of the exemplary narratives of the modern era. And governments, which typically focus on crude measures of economic performance, encourage rapid urbanization. Which of the following is the main concern of the writer in the above passage? OPTIONS     1) Movement of the rural poor to the large cities.   2) Metropolises as engines of growth for global economy.   3) Deterioration of the quality of life in the fast growing city of Bangalore.   4) The main issue for the people in Bangalore in the forthcoming state elections.

Bharath, the mathematics genius and professor, asked his students to identify the following table:

Vicky (instantly raising his hand): Come on sir, we all know this is a Magic Square. The sum of the numbers in any row, column or diagonal adds up to 15. Also, a magic square of this type can be created using any 9 numbers in an arithmetic sequence.

Bharath: Well said Vicky. That was very informative for all of us. Now have a look at this and tell me what you can find in it.

Bharath (after a 5 minute silence): Looks like I’ll have to reveal the answer this time.

Nithin: I got it sir. The previous one was a Sum Magic Square, whereas this one is a Difference Magic Square.

Bharath: Now that’s more like it Nithin. Tell me more.

Nithin: Take any row, column or diagonal. Subtract the 1^st number from the 2^nd and subtract the result from the 3^rd number. You get the result 5 in each case. For instance, the second row gives you 7 − (5 − 3) = 5 and the second column gives 9 – (5 – 1) = 5; and so on.

Bharath: Excellent work Nithin. I’m impressed. Anyway guys, get ready for the next challenge. This is your homework. I want all of you to create a Multiplication Magic Square. Choose any set of nine numbers that you want, and create a Magic Square based on multiplication, similar to the one on Addition, i.e., the product of the numbers in any row, column or diagonal must be the same. Also, this should be the smallest multiplication square possible.

Vicky: This seems tough sir. A few clues on this would help us.

Bharath: Alright Vicky, the 9 numbers you choose, must be the only 9 factors of a given number. I can’t tell you more than this.
