Discussed Questions

DIRECTIONS for the questions : The four sentences (labelled a, b, c, d) given below, when property sequenced would yield a coherent paragraph. Decide on the proper sequence of the order of the sentences and key in the sequence of the four numbers as your answer.
(2019)
A. Conceptualisations of ‘women’s time’ as contrary to clock-time and clock-time as synonymous with economic rationalism are two of the deleterious results of this representation.
B. While dichotomies of ‘men’s time’, ’women’s time’, clock-time, and caring time can be analytically useful, this article argues that everyday caring practices incorporate a multiplicity of times; and both men and women can engage in these multiple-times
C. When the everyday practices of working sole fathers and working sole mothers are carefully examined to explore conceptualisations of gendered time, it is found that caring time is often more focused on the clock than generally theorised.
D. Clock-time has been consistently represented in feminist literature as a masculine artefact representative of a ‘time is money’ perspective.

Read all the options or sentences. The first sentence is sentence (d) because this sentence is in the nature of introduction or simple definition of clock time which has been discussed at a more complex level in the other options. Sentence (d) talks of the representation of clock-time. The next sentence where there is reference of this representation with the use of the word representation is sentence (a). So the sequence we get is (d, a).
The next sentence will be sentence (c). Let us see how. Sentence (a) talks of deleterious effect which is harmful effect. The theme of negative or deleterious effect is further extended in sentence number (c) “it is found that caring time is often more focused on the clock than generally theorised” We are now left with sentence number (b), which is a form of conclusion to the introduction of an article as evident from “this article argues....” in the sentence number (b). So the right sequence is (d, a, c, b).

Which organelles in the cell other than the nucleus, contain DNA?
  • a)
    Ribosome
  • b)
    Golgi Apparatus
  • c)
    Lysosome
  • d)
    Mitochondria
Correct answer is option 'D'. Can you explain this answer?

BT Educators answered  •  Feb 22, 2025
Besides the Nucleus, Mitochondrial DNA is the small circular chromosome found inside mitochondria. The mitochondria are organelles found in cells that are the sites of energy production. The mitochondria, and thus mitochondrial DNA, are passed from mother to offspring.
Hence, the correct option is (D).

Read the passage carefully and answer the following questions:
Around 2700 years ago, the Greek poet Archilochus wrote: “the fox knows many things; the hedgehog one big thing.” In the 1950s, philosopher Isaiah Berlin used that sentence as the basis of his essay “The Hedgehog and the Fox.” In it, Berlin divides great thinkers into two categories: hedgehogs, who have one perspective on the world, and foxes, who have many different viewpoints. Although Berlin later claimed the essay was not intended to be serious, it has become a foundational part of thinking about the distinction between specialists and generalists.
A generalist is a person who is a competent jack of all trades, with lots of divergent useful skills and capabilities. Specialist, on the other hand, is someone with distinct knowledge and skills related to a single area. The generalist and the specialist are on the same continuum; there are degrees of specialization in a subject. There’s a difference between someone who specializes in teaching history and someone who specializes in teaching the history of the American Civil war, for example. Likewise, there is a spectrum for how generalized or specialized a certain skill is. Some skills — like the ability to focus, to read critically, or to make rational decisions — are of universal value. Others are a little more specialized but can be used in many different careers. Examples of these skills would be design, project management, and fluency in a foreign language.
Generalists have the advantage of interdisciplinary knowledge, which fosters creativity and a firmer understanding of how the world works. They have a better overall perspective and can generally perform second-order thinking in a wider range of situations than the specialist can. Generalists often possess transferable skills, allowing them to be flexible with their career choices and adapt to a changing world. Managers and leaders are often generalists because they need a comprehensive perspective of their entire organization. And an increasing number of companies are choosing to have a core group of generalists on staff, and hire freelance specialists only when necessary. The métiers at the lowest risk of automation in the future tend to be those which require a diverse, nuanced skill set.
When their particular skills are in demand, specialists experience substantial upsides. The scarcity of their expertise means higher salaries, less competition, and more leverage. The downside is that specialists are vulnerable to change. Many specialist jobs are disappearing as technology changes. Stockbrokers, for example, face the possibility of replacement by AI in coming years. That doesn’t mean no one will hold those jobs, but demand will decrease. Many people will need to learn new work skills, and starting over in a new field will put them back decades. That’s a serious knock, both psychologically and financially.
What’s the safest option, the middle ground? By many accounts, it’s being a specialist in one area, while retaining a few general iterative skills-a generalizing specialist. Many great thinkers are (or were) generalizing specialists. Shakespeare, Da Vinci, Kepler, and Boyd excelled by branching out from their core competencies. These men knew how to learn fast, picking up the key ideas and then returning to their specialties. Unlike their forgotten peers, they didn’t continue studying one area past the point of diminishing returns; they got back to work — and the results were extraordinary.
Q. Which of the following are examples of a generalist?
I. An eminent psychologist who works with the news media, publishes research papers and teaches a broad range of topics online.
II. A nuclear scientist specialising in the field of nuclear fusion and plasma science.
III. A manager with diverse work experience who works with a leading pharmaceutical company. 
IV. A distinguished athlete who has won 9 Olympic medals in swimming.

A generalist should have divergent useful skills and capabilities as per the passage. Hence the example should convey that the person possesses various skills/capabilities.
The psychologist described in statement I is a generalist as he has interdisciplinary knowledge and possesses transferrable skills. Hence he can be classified as a generalist.
Since the scientist specialises in one domain, we cannot say that he is a generalist. Statement II can be eliminated.
In the third paragraph, the author states that " Managers and leaders are often generalists because they need a comprehensive perspective of their entire organization." Hence, the manager mentioned in Statement III is a generalist.
 A swimmer specialises in one sport and therefore, we cannot say that he is a generalist. Statement IV can be eliminated.
Hence, only Statements I and III are valid. Option A is the answer.

2 logx + 4 logx - 3 logy + 6 logx - 6 logy + 8 logx - 9 logy + + 2n logx - 3(n - 1) logy
Alternative Solution
This question can also be answered by eliminating the answer choices. By substituting n = 1, choices (b), (c) get eliminated and for n = 2; choice (d) is eliminated.
∴Only choice (a) can be the answer.

Directions for Questions: 
Healthy Bites is a fast food joint serving three items; burgers, fries and ice cream. It has two employees Anish and Bani who prepare the items ordered by the clients. Preparation time is 10 minutes for a burger and 2 minutes for an order of ice cream. An employee can prepare only one of these items at a time. The fries are prepared in an automatic fryer which can prepare up to 3 portions of fries at a time, and takes 5 minutes irrespective of the number of portions. The fryer does not need an employee to constantly attend to it, and we can ignore the time taken by an employee to start and stop the fryer; thus, an employee can be engaged in preparing other items while the frying is on. However fries cannot be prepared in anticipation of future orders.
Healthy Bites wishes to serve the orders as early as possible. The individual items in any order are served as and when ready; however, the order is considered to be completely served only when all the items of that order are served.
The table below gives the orders of three clients and the times at which they placed their orders:
(2017)
Q. Suppose the employees are allowed to process multiple orders at a time, but the preference would be to finish orders of clients who placed their orders earlier.

जब किसी व्यक्ति को निवारक निरोध के अधीन गिरफ्तार किया जाता है, तब-
  • सरकार ऐसे व्यक्ति को केवल 3 महीने तक अभिरक्षा में निरुद्ध कर सकती है। 
  • यदि गिरफ्तार व्यक्ति को 3 माह से अधिक के लिए निरुद्ध करना होता है तो इसके लिए सलाहकार बोर्ड का प्रतिवेदन प्राप्त करना पड़ता है।
