PART – ‘B’ (5 x 16 = 80 marks)
Ethanol is a renewable, domestically produced transportation fuel. Whether used in lowlevel
blends, such as E10 (10% ethanol, 90% gasoline), or in E85 (a gasoline-ethanol blend
containing 51% to 83% ethanol, depending on geography and season), ethanol helps
reduce imported oil and greenhouse gas emissions. Like any alternative fuel, there are
some considerations to take into account when contemplating the use of ethanol.
About two-thirds of U.S. petroleum demand is in the transportation sector. Approximately
half of U.S. petroleum is imported. Depending heavily on foreign petroleum supplies puts
the United States at risk for trade deficits, supply disruption, and price changes. The
Renewable Fuels Association's 2012 Ethanol Industry Outlookcalculated that in 2011 the
ethanol industry replaced the gasoline produced from more than 485 million barrels of
imported oil. Ethanol represents 25% of domestically produced and refined motor fuel for
gasoline engines.
A gallon of ethanol contains less energy than a gallon of gasoline. The result is lower fuel
economy than a gallon of gasoline. The amount of energy difference varies depending on
the blend. For example, E85 has about 27% less energy per gallon than gasoline (mileage
penalty lessens as ethanol content decreases). However, because ethanol is a high-octane
fuel, it offers increased vehicle power and performance.
Ethanol production creates jobs in rural areas where employment opportunities are
needed. According to Renewable Fuels Association, ethanol production in 2011 supported
more than 400,000 jobs across the country, \$42.4 billion to the gross domestic product, and
\$29.9 billion in household income.
The carbon dioxide released when ethanol is burned is balanced by the carbon dioxide
captured when the crops are grown to make ethanol. This differs from petroleum, which is
made from plants that grew millions of years ago. On a life cycle analysis basis, cornbased
ethanol production and use reduces greenhouse gas emissions (GHGs) by up to 52%
compared to gasoline production and use. Cellulosic ethanol use could reduce GHGs by as
much as 86%.
Low-level ethanol blends are already in more than 95% of the gasoline sold in the United
States. Low-level blends require no special fueling equipment and can be used in any
gasoline vehicle. E85 fueling equipment is only slightly different than petroleum fueling
equipment, but the costs are higher. FFVs are available nationwide as standard equipment
with no incremental costs, making them an affordable alternative fuel vehicle option.
However, because most U.S. ethanol plants are concentrated in the Midwest, fueling
stations offering E85 are predominately located in the Corn Belt states. More and more
states are installing E85 every day. Find E85 fuelling stations in your area.

11. ii) Read the excerpts from an interview with the former President of India APJ Abdul Kalam
and answer the questions given below:
Today, greatness is largely measured by material wealth, and this in turn brings
about discontent in society. Do you feel there is a need for us to shun materialism as
I studied till High School in British India. In 1947, we got freedom and I started living in
India’s India. I have seen various transformations in society, be it the economy or the value
system. While our economy is developing, we need citizens with ethics and a value
system. For the last 10 years I’ve been promoting an idea called Evolution of Enlightened
Citizens. It has three dimensions. One is education with value system. This comes from the
family, or may be from a primary school teacher. After all, the evolution of enlightened
citizens is essential for India and the world. Second, the dimension is economic prosperity.
Third, religion should transform into a spiritual force. I advocate these three.
I have given lectures in our Parliament, addressed the European parliament of 23 nations, a
pan-African parliament of 53 nations, and the Korean parliament. I am not saying the
Indian value system should be taken to other countries. They also have great leaders and
traditions based on their value system. I believe that one’s value system, the joint family
system, economic growth and different religions transforming into a spiritual force are
vital. That’s why I have shared this at various interactive forums.

Your work gives pre-eminence to inspiring and changing the thought pattern of the
youth. However, as we see the country deluged with problems such as hunger,
disease, deteriorating environment and unfit living conditions, how long will it take to
see change, or is it already visible?
Thought is the seed of action. Thought is as ancient as Socrates. Tiruvalluvar, 2,200 years
ago, has also said that…That’s why I proposed in Parliament that we need India Vision
2020. That is, by 2020, India should become economically developed. Even now, it’s not
too late. Parliament should consider how it can activate the vision for the nation, so
prosperity can be aimed at. Our priority should be to use PURA – ‘providing urban
amenities in rural areas’. Our farmers are producing 250 million tonnes of food. But we
don’t do value addition, which means greater export potential. We are leading producers of
fruits and vegetables but we don’t process these as juice or packaged food. And third, of
course, small scale industries which are spread across the country.
Are you in touch with the PURA projects, and are these showing results?
I have seen in Madhya Pradesh, the Chitrakoot PURA founded by NanajiDeshmukh. He is
a pioneer and they are doing very well, more than 500 villages are connected, and there is
prosperity. Another one I saw in Maharashtra, Warana PURA. There is no poverty there,
because the cooperative movement is doing very well. And the third I have seen in Tamil
Nadu at Vallam, Thanjavur.I am in touch with these three, and visit them often. But apart
from that, the Government of India has started a few PURAs with public-private
participation. The number of PURAs is increasing. But it has to be fast. After all, there are
600,000 villages; we have to establish 7000 PURAs in 10-15 years’ time. We have less
than 100.
Your writing reflects great contentment, yet this never stops you from action.
God helps only those who work hard. There is nothing like contentment. Success is not the
ultimate aim. However, at no time should you allow your problems to overwhelm you. I
can’t say that I am content, because I meet 80,000 to 100,000 youth a month. I know their
dreams, their pain. A nation without a vision dies. Parliament has to give this vision.
Write short answers for the following questions: (4 x 2 = 8)
1) Kalam says: ‘A nation without vision dies.’ Comment on this statement.
2) How do PURA projects make the country achieve economic prosperity?
3) India Vision 2020 is only a dream which cannot be achieved. Do you agree with this
4) What will be the future of India after a period of ten years?
memorable day with a focus on inaugural function, classes,campus visit and so on.
