QUESTION: 1

Accountability, or the lack of it, in governance generally, and civil services, in particular, is a major factor underlying the deficiencies in governance and public administration. Designing an effective framework for accountability has been a key element of the reform agenda. A fundamental issue is whether civil services should be accountable to the political executive of the day or to society at large. In other words, how should internal and external accountability be reconciled? Internal accountability is sought to be achieved by internal performance monitoring, official supervision by bodies like the —Central-Vigilance Commission-andComptroller and Auditor—General, and judicial review of executive decisions. Articles 311 and 312 of the Indian Constitution provide job security and safeguards to the civil services, especially the All India Services. The framers of the Constitution had envisaged that provision of these safeguards would result in a civil service that is not totally subservient to the political executive but will have the strength to function in larger public interest. The need to balance internal and external accountability is thus built into the Constitution. The issue is where to draw the line. Over the years, the emphasis seems to have tilted in favour of greater internal accountability of the civil services to the political leaders of the day who in turn are expected to be externally accountable to the society at large through the election process. This system for seeking accountability to Society has not worked out, and has led to several adverse consequences for governance.
Some special measures can be considered for improving accountability in civil services.
Provisions of articles 311 and 312 should be reviewed and laws and regulations framed to ensure external accountability of civil services. The proposed Civil Services Bill seeks to address some of these requirements. The respective roles of professional civil services and the political executive should he defined so that professional managerial functions and management of civil services are depoliticized. For this purpose, effective statutory civil service boards should be created at the centre and in the states. Decentralization and devolution of authority to bring government and decision making closer to the people also helps to enhance accountability.

 

Q. According to the passage, which of the following factor/factors led to the adverse consequences for governance/public administration?

1. Inability of civil services to strike a balance between internal and external accountabilities 

2. Lack of sufficient professional training to the officers of All India Services

3. Lack of proper service benefits in civil services

4. Lack of Constitutional provisions to define the respective roles of professional civil services vis-a-vis political executive in this context

Q. According to the passage, which one of the following is not a means of enhancing internal accountability of civil services?

Solution:
QUESTION: 5

In general, religious traditions stress our duty to god, or to some universal ethical principle. Our duties to one another derive from these. The religious concept of rights is primarily derived from our relationship to this divinity or principle and the implication it has on our other relationships. This correspondence between rights and duties is critical to any further understanding of justice. But, for justice to be practiced; rights and duties cannot remain formal abstraction. They must be grounded in a community (common unity) bound together by a sense of common union (communion). Even as a personal virtue, this solidarity is essential to the practice and understanding of justice.

QUESTION: 13

There are five hobby clubs in a college —photography, yachting, chess, electronics and gardening. The gardening group meets every second day, the electronics group meets every third day, the chess group meets every fourth day, the yachting group meets every fifth day and the photography group meets every sixth day. How many times do all the five groups meet on the same day within 180 days?

Solution:

Take the LCM. of 2, 3, 4, 5, 6 = 60 
So every 60th day all five hobby clubs meet. So in a period of 180 days they meet thrice i.e. on 60th, 120th and 180th day.
Hence, Option D.
 

QUESTION: 14

There are some nectar-filled flowers on a tree and some bees are hovering on it. If one bee lands on each flower, one bee will be left out. If two bees land on each flower, one flower will be left out. The number of flowers and bees respectively are:

Solution:

Let the number of bees = x 
Then the number of flowes = (x - 1) 
If the number of bees sitting on each flower is 2, number of flowers is (x / 2 + 1) 
⇒ (x / 2 + 1) = (x - 1) 
⇒  x - x / 2 = 2 
⇒ x / 2 = 2 
⇒ x = 4 
Therefore, number of bees is 4 and the number of flowers is
(4 - 1) i.e. 3.

QUESTION: 21

​Biomass as fuel for power, heat, and transport has the highest mitigation potential of all renewable sources. It comes from agriculture and forest residues as well as from energy crops.

The biggest challenge in using biomass residues is a long-term reliable supply delivered to the power plant at reasonable costs; the key problems are logistical constraints and the costs of fuel collection. Energy crops, if not managed properly, compete with food production and may have undesirable impacts on food prices. Biomass production is also sensitive to the physical impacts of a changing climate.

Projections of the future role of biomass are probably overestimated, given the limits to the sustainable biomass supply, unless breakthrough technologies substantially increase productivity. Climate-energy models project that biomass use could increase nearly four-fold to around 150 — 200 exajoules, almost a quarter of world primary energy in 2050. However the maximum sustainable technical potential of biomass resources (both residues and energy crops) without disruption of food and forest resources ranges from 80 — 170 exajoules a year by 2050, and only part of this is realistically and economically feasible. In addition, some climate models rely on biomass-based carbon capture and storage, an unproven technology, to achieve negative emissions and to buy some time during the first half of the century.

Some liquid biofuels such as corn-based ethanol, mainly for transport, may aggravate rather than ameliorate carbon emissions on a life-cycle basis. Second generation biofuels, based on ligno-cellulosic feedstocks — such as straw, bagasse, grass and wood — hold the promise of sustainable production that is high-yielding and emit low levels of greenhouse gases, but these are still in the R & D stage.

 

Q. What is/are the present constraint/constraints in using biomass as fuel for power generation?

1. Lack of sustainable supply of biomass

2. Biomass production competes with food production

3. Bio-energy may not always be low carbon on a life-cycle basis

Q.  Which of the following can lead to food security problem?

1. Using agricultural and forest residues as feedstock for power generation

2. Using biomass for carbon capture and storage

3. Promoting the cultivation of energy crops Select the correct answer using the code given below:

Solution:

The correct option is Option B.
Biofuels and biofuel crops have been vaunted by politicians, journalists and scientists for years. A method of producing fuel from plants or other sources could potentially allow us to decrease our dependence on fossil fuels. Energy crops, so-called, include wheat, corn, soybean and sugarcane.
Rapid growth in biofuel production will continue to influence food prices and this in turn will have an impact on food security. In addition, higher transport costs increased the costs of imported food affecting even further countries with a high dependence on imported petroleum products and cereals.

QUESTION: 25

We are witnessing a dangerous dwindling of biodiversity in our food supply. The green revolution is a mixed blessing. Over time farmers have come to rely heavily on broadly adapted, high yield crops to the exclusion of varieties adapted to the local conditions. Mono-cropping vast fields with the same genetically uniform seeds helps boost yield and meet immediate hunger needs. Yet high-yield varieties are also genetically weaker crops that require expensive chemical fertilizers and toxic pesticides. In our focus on increasing the amount of food we produce today, we have accidentally put ourselves at risk for food shortages in future.

QUESTION: 26

A class starts at 11:00 am and lasts till 2:27 pm. Four periods of equal duration are held during this interval. After every period, a rest of 5 minutes is given to the students. The exact duration of each period is:

Solution:

Class ends at 02:27 pm
So, duration of class = 3h 27min = 207 min 

There will be 4 periods.
After every period, there will be a 5 min break. Here, only 3 breaks will be taken as there are only 4 periods and end of 4th periodmeansend of the class.4th break is not needed to beconsidered.
So, duration of the periods = 207 – 3×5 = 192 min.

Time assigned to each period = 192/4 =48min.

QUESTION: 27

Four friends A, B, C and D need to cross a bridge. A maximum of two persons can cross it at a time. It is night and they just have one lamp. Persons that cross the bridge must carry the lamp to find the way. A pair must walk together at the speed of slower person. After crossing the bridge, the person having faster speed in the pair will return with the lamp each time to accompany another person in the group. Finally, the lamp has to be returned at the original place and the person who returns the lamp has to cross the bridge again without lamp. To cross the bridge, the time taken by them is as follows : A: 1 minute, B: 2 minutes, C: 7 minutes and D: 10 minutes. What is the total minimum time required by all the friends to cross the bridge?

Solution:

(a) Here, A takes the shortest time to cross the bridge i.e. 1 min. And, D takes 10 min, C takes 7 min and B takes 2 min to cross the bridge. So, 4 friends can cross the bridge in minimum time in the following ways. 1. A + B crossing and A returning : (2 + 1) min 2. A + C crossing and A returning : (7 + 1) min 3. A + D crossing and A returning : (10 + 1) min 4. A crossing the bridge for the lasttime : 1 min. Hence, total minimum time = 3 + 8 + 11 + 1 = 23 min.

In aid of charity, every student in a class contributes as many rupees as the number of students in that class. With the additional contribution of Rs. 2 by one student only, the total collection is Rs. 443. Then how many students are there in the class?

Solution:

The correct answer is Option B.
X number of students denoted equal amount ie X × X rs
And Rs2 extra gives 443
So,
X² + 2 = 443
X² = 441
X = 21

QUESTION: 30

Anita’s mathematics test had 70 problems carrying equal marks i.e., 10 arithmetic, 30 algebra and 30 geometry. Although she answered 70% of the arithmetic, 40% of the algebra and 60% of the geometry problems correctly, she did not pass the test because she got less than 60% marks. The number of more questions she would have to answer correctly to earn a 60% passing marks is:

Solution:

(b) Questions correctly answered by Anita are as follows: Arithmetic – 70% of 10 = 7 
Algebra – 40% of 30 = 12 
Geometry – 60% of 30 = 18  
Total questions correctly answered = 7 + 12 + 18 = 37 
Anita had to attempt 60% of 70 questions i.e., 42 questions correctly to pass the test. 
Number of more questions required to be answered = 42 – 37 = 5

Understanding of the role of biodiversity in the hydrological cycle enables better policy-making.
The term biodiversity refers to the variety of plants, animals, microorganisms, and the ecosystems in which they occur. Water and biodiversity are interdependent. In reality, the hydrological cycle decides how biodiversity functions. In turn, vegetation and soil drive the movement of water. Every glass of water we drink has, at least in part, passed through fish, trees, bacteria, soil and other organisms. Passing through these ecosystems, it is cleansed and made fit for consumption. The supply of water is a critical service that the environment provides.

Safe and sustainable sanitation in slums has immeasurable benefits to women and girls in terms of their health, safety, privacy and dignity. However, women do not feature in most of the schemes and policies on urban sanitation. The fact that even now the manual scavenging exists, goes to show that not enough has been done to promote pour-flush toilets and discontinue the use of dry latrines. A more sustained and rigorous campaign needs to be launched towards the right to sanitation on a very large scale. This should primarily focus on the abolition of manual scavenging.

 

Q. With reference to the above passage, consider the following statements:

1. Urban sanitation problems can be fully solved by the abolition of manual scavenging only

2. There is a need to promote greater awareness on safe sanitation practices in urban areas.

Solution:
QUESTION: 66

All humans digest mother’s milk as infants, but until cattle began being domesticated 10,000 years ago, children once weaned no longer needed to digest milk. As a result, they stopped making the enzyme lactase, which breaks down the sugar lactose into simple sugars. After humans began herding cattle, it became tremendously advantageous to digest milk, and lactose tolerance evolved independently among cattle herders in Europe, the middle East and Africa.
Groups not dependant on cattle, such as the Chinese and Thai, remain lactose intolerant.

An increase in human-made carbon dioxide in the atmosphere could initiate a chain reaction between plant and microorganisms that would unsettle one of the largest carbon reservoirs on the planet soil In a study, it was found that the soil, which contains twice the amount of carbon present in a plants and Earth’s atmosphere combined, could become increasingly volatile people add more carbon dioxide to the atmosphere. This is largely because of increased plant growth.
Although a greenhouse gas and a pollutant, carbon dioxide also supports plant growth. As trees and other vegetation flourish in a carbon dioxide-rich future, their roots could stimulate microbial activity in soil that may in turn accelerate the decomposition of soil carbon and its relsase into the atmosphere as carbon dioxide.

QUESTION: 69

Historically, the biggest Challenge to world agriculture has been to achieve a balance between demand for and supply of food. At the level of individual countries, the demand-supply balance can be a critical issue for a closed economy, especially if it is a populous economy and its domestic agriculture is not growing sufficiently enough to ensure food supplies, on an enduring basis; it is not so much and not always, of a constraint for an open, and growing economy, which has adequate exchange surplus to buy food abroad. For the world as a whole, supply-demand balance is always an inescapable prerequisite for warding off hunger and starvation. However, global availability of adequate supply does not necessarily mean that food would automatically move from countries of surplus to of deficit if the latter lack in purchasing power. The uneven distribution of hunger, starvation, under or mal-nourishment, etc., at the world-level, thus owes itself to the presence of empty-pock hungry mouths, overwhelmingly confined to the underdeveloped economies. In as much as ‘a two-square meal’ is of elemental significance to basic human existence, the issue of worldwide supply of food has been gaining significance, in recent times, both because the quantum and the composition of demand has been undergoing big changes, and because, in recent years, the capabilities of individual countries to generate uninterrupted chain of food supplies have come under strain. Food production, marketing and prices, especially price-affordability by the poor in the developing world, have become global issues that need global thinking and global solutions.

 

Q. According to the above passage, which of, the following are the fundamental solutions for the world food security problem?

For the world as a whole, supply-demand balance is always an inescapable prerequisite for warding off hunger and starvation. However, global availability of adequate supply does not necessarily mean that food would automatically move from countries of surplus to of deficit if the latter lack in purchasing power. The uneven distribution of hunger, starvation, under or mal-nourishment, etc., at the world-level, thus owes itself to the presence of empty-pock hungry mouths, overwhelmingly confined to the underdeveloped economies. In as much as ‘a two-square meal’ is of elemental significance to basic human existence, the issue of worldwide supply of food has been gaining significance, in recent times, both because the quantum and the composition of demand has been undergoing big changes, and because, in recent years, the capabilities of individual countries to generate uninterrupted chain of food supplies have come under strain. Food production, marketing and prices, especially price-affordability by the poor in the developing world, have become global issues that need global thinking and global solutions.

Q. A and B walk around a circular park. They start at 8 a.m. from the same point in the opposite directions. A and B walk at a speed of 2 rounds per hour and 3 rounds per hour respectively. How many times shall they cross each other after 8 00 a.m. and before 9.30. a.m.?

Solution:

The correct answer is A as Relative speed = (2 + 3) km/hr = 5 km/hr This means that A and B cross each other 5 times in a hour and at least 2 times in half an hour
∴ They cross each other 7 times before 9:30 a.m.

Q. The average monthly income of a person in a certain family of 5 is Rs. 10,000.
What will be the average monthly income of a person in the same family if the income of one person increased by Rs. 1,20,000 per year?

Solution:

Salary increased of a person yearly =1,20,000
Monthly = 1,20,000 / 12 = 10,000
Average increased = 10,000 / 5 = 2,000
Net average = 10,000 + 200 = 12,000.

Q. A round archery target of diameter 1 m is marked with four scoring regions from the centre outwards as red, blue, yellow and white. The radius of the red band is 0.20 m. The width of all the remaining bands is equal. If archers throw arrows towards the target, what is the probability, that the arrows fall in the red region of the archery target?

Solution:

We know that, area of a circle = πr2
So, Red band area = π(0.2)2 = 0.04π
All the other than red are in the form of a ring. So,
