Group QuestionAnswer the following question based on the information g...
To solve this question, we can use the principle of inclusion-exclusion. Let's break down the information given into different categories:

1. Students specialising in Salsa and Belly dancing = 100
2. Students specialising in Salsa and Hip-Hop dancing = 70
3. Students specialising in Belly and Hip-Hop dancing = 50

We are also told that among the remaining students, an equal number specialise in each of the other possible dual dance categories. Let's call this number 'x'.

Now, let's use the principle of inclusion-exclusion to find the total number of students who specialise in Belly dance:

1. Total number of students specialising in Salsa and Belly dancing = 100
2. Total number of students specialising in Salsa and Hip-Hop dancing = 70
3. Total number of students specialising in Belly and Hip-Hop dancing = 50
4. Total number of students specialising in Salsa, Belly, and Hip-Hop dancing = x

To find the total number of students specialised in Belly dance, we can add the following:

Total number of students specialising in Salsa and Belly dancing + Total number of students specialising in Belly and Hip-Hop dancing - Total number of students specialising in Salsa, Belly, and Hip-Hop dancing

= 100 + 50 - x

But we also know that the total number of students in the group is 400. So, we can equate the above expression to 400 and solve for x:

100 + 50 - x = 400
150 - x = 400
x = 150 - 400
x = -250

This means that there is no student specialising in all three dance forms. However, since we are told that an equal number of students specialise in each of the other possible dual dance categories among the remaining students, we can assume that x is positive.

To find the total number of students specialising in Belly dance, we can substitute the value of x back into the expression:

100 + 50 - x = 100 + 50 - (-250) = 150 + 250 = 400

Therefore, the correct answer is 400.

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 wer e) 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 statements CANNOT be inferred from the passage?
