Read the following passages and answer the questions that follow each passage. Your answer to these questions should be based on passage only. 

Passage 1 

Nature writing is nonfiction or fiction prose or poetry about the natural environment. Nature writing encompasses a wide variety of works, ranging from those that place primary emphasis on natural history facts (such as field guides) to those in which philosophical interpretation predominate. It includes natural history essays, poetry, essays of solitude or escape, as well as travel and adventure writing. 

Nature writing often draws heavily on scientific information and facts about the natural world; at the same time, it is frequently written in the first person and incorporates personal observations of and philosophical reflections upon nature. 

Modern nature writing traces its roots to the works of natural history that were popular in the second half of the 18th century and throughout the 19th. An important early figure was the “parson-naturalist” Gilbert White (1720 – 1793), a pioneering English naturalist and ornithologist. He is best known for his Natural History and Antiquities of Selborne (1789). 

Q.31) Which of the following statement best summarizes the above passage? 

  1. The passage talks about the life and lessons of Gilbert White, a profound naturalist and ornithologist. 
  2. The passage talks about how the nature writing is missing in the modern era and needs to be revived. 
  3. The passage talks about from where the writers draw inspiration for nature writing, and how its importance is diminishing in the modern era. 
  4. The passage talks about what nature writing is, the different type of nature writing, its style, and about the roots and pioneer of modern nature writing. 

Passage 2 

Many sociologists have argued that there is functional relationship between education and economic system. They point to the fact that mass formal education began in industrial society. They note that the expansion of the economies of industrial societies is accompanied by a corresponding expansion of their educational systems. They explain this correspondence in terms of the needs of industry for skilled and trained manpower, needs which are met by the educational system. Thus, the provision of mass elementary education in Britain in 1870 can be seen as a response to the needs of industry for a literate and numerate workforce at a time when industrial processes were becoming more complex and the demand for technical skills was steadily growing. 

Q.32) The industry needs a literate work-force because 

  1. its expansion needs sound learning 
  2. it relies heavily on expertise 
  3. it promotes a competitive spirit 
  4. its operations need intricate technical knowledge

What IMPACT can the ‘60 Day’ have on the final results? We will explain by taking a small example. Imagine you are sitting in the examination hall, appearing in Prelims Paper I. You have attempted 70 questions already but still unsure about a few. Then you stumble upon a question that was asked in 60 Day (and believe us, it has happened to hundreds of students countless times). You choose the right answer and submit your paper hoping for the best! Eventually, you go on to clear Mains as well as Personality Test and secure a good rank as well. When the cut off gets announced by UPSC, you realize that you have scored just one mark more than the cut off! Yes, that one mark can change your life (and it has done so to many of our students in the past). Now, imagine the kind of impact 60 to 80 marks can have! Isn’t that so fascinating to imagine?  

One’s level of preparedness is always different for different subjects. Even within a subject, one’s comfort level may vary with topics. For example, one might be more comfortable in solving questions of Polity than Economics and within Polity also, one might be at ease with questions on fundamental rights than Parliament. The level of comfort and ease that one has with a subject/ topic gets manifested in the examination. However, there is no conscious effort by aspirants to micro analyze these aspects. Now, coming to the second aspect i.e. the mistakes that one commits in answering MCQs, it can be said that there are mainly four reasons behind incorrect responses in the OMR sheet. They are:

  1. Lack of information
  2. Lack of analytical ability
  3. Silly mistakes
  4. Excessive risk-taking

Let’s analyze them one by one:

  1. Lack of information: You simply don’t know the information. You are clueless and that’s why you don’t attempt the question. For example, you may have never come across a regime called the ‘Wassenaar Agreement’ during your preparation and you can’t do much about it. The lack of information is pardonable and rectifiable. You can read more and gather more information. That is within your reach.
  2. Lack of analytical ability: You know the concept but the question is a twisted one and you are not able to apply the concept. For example, in a question asking you to identify the climate type of a region based on certain given parameters like precipitation, temperature, and air density, you might find it difficult to mark the correct option even if you are aware of all the options given in the question! That is clearly a lack of application and you can overcome it by developing a habit of framing questions in your mind while you study any topic.
  3. Silly mistakes: This habit is unpardonable. You know the concept, you become happy, you misread the question, you mark the incorrect answer and you are out of the race! Such mistakes reveal your hurriedness while answering the question. A simple mistake of reading ‘chose the incorrect option’ as ‘chose the correct option’ can destroy your chances. It means that you need to have patience and focus while attempting the paper.
  4. Excessive risk-taking: You are confused between the options and just in order to increase your attempts, you make wild guesses and try your luck only to repent eventually. Risk-taking is an art and one must be very careful while doing the guesswork in confusing questions. If you are not lucky enough, it can spoil your chances.

You will realize that these problems will have different meanings for different people. For example, one might find a lack of information as the main culprit in answering wrong the questions on Culture while in Polity, lack of analytical ability is usually the culprit. The point here is that you must analyse your preparation on these yardsticks by applying them on different subjects/ topics. If one is having a headache, he/ she can’t have the same medicine for fever. Isn’t it.

This is where our revamped ’60 Day’ comes into the picture. It will give you an opportunity to micro analyze your preparation and perform better in the examination.

Finally, it is up to you to take advantage of this framework. We are sure of only one thing- if you follow this program, assess yourself on the basis of the given framework and keep improving your weaker areas, success will be yours.

We are providing you with the right platform, the right guidance, and the right competition. Do you have the right motivation to make full use of this initiative? We think you have. Come, be a part of this initiative and take the first step towards SUCCESS!

Importance of self – tracking:

We could have provided all of you with login id and passwords to monitor your daily performance in the 60-day program.

Instead, a simple and most beautiful way which Disqus provides is profile based commenting!

Yes, we have seen the most successful candidates who have taken the maximum benefit from this program monitoring themselves by commenting on their answers in the box given (Disqus comment). And reviewing their performance themselves once in 10 days on the progress meter.
