Read the following passage and answer the questions that follow.
Indian mathematician Nikhil Srivastava, working at the University of California in Berkeley, is among the winners of the Prestigious 2021 Michael and Sheila Held Prize, announced last week by the US National Academy of Sciences (NAS). Adam W. Marcus, EPFL (Swiss Federal Institute of Technology, Lausanne), and Daniel Alan Spielman, Yale University, are the other two winners.
"Marcus, Spielman, and Srivastava solved longstanding questions on the Kadison-Singer problem and on Ramanujan graphs, and in the process, they uncovered a deep new connection between linear algebra, the geometry of polynomials, and graph theory that has inspired the next generation of theoretical computer scientists," the NAS said in a statement.
An Indian national, Nikhil was born in New Delhi in November 1983 and has attended educational institutions across the world—Syria, the UK, Saudi Arabia, and the US—as his father was an Indian Foreign Services officer, who has served as the Indian ambassador to Uganda and Denmark. At present, Nikhil is an associate professor of mathematics at UC Berkeley. The Michael and Sheila Held Prize is presented annually to honour outstanding, innovative, creative, and influential research in the area of combinatorial mathematics.
Question:
How many mathematicians won the Michael Sheila Prize for 2021?
Option 1: Four
Option 2: Two
Option 3: Three
Option 4: One
Correct Answer: Three
Solution : The correct choice is the third option.
As stated in the first paragraph, the prize was won by Nikhil Srivastava, Adam W. Marcus, and Daniel Alan Spielman, which makes this a total of three prize winners.
Therefore, the correct answer is three.
I Am 8th Icse so i have to choose commerce or computer Science- what should i choose which is scoring and easy subject
Hello,
I believe I can answer this question correctly as I had the same option when I was in class 9th. I chose computer and trust me, it's way difficult especially if you are not into computer programming. You'll have to learn computer programming like JAVA, HTML, etc. It will be pretty easy in class 9th but it will get difficult in class 10th. However, if you are well versed with it and are interested, trust me it's a really scoring subject.
If you just want to go with an easier subject, go for commerce.
I hope this helps,
Thank you

In the following passage, some words have been deleted. Read the passage carefully and select the most appropriate option to fill in each blank.
The world is undergoing rapid changes in the knowledge landscape. With various dramatic scientific and technological advances, such as the rise of big data, machine learning, and artificial intelligence, many unskilled jobs worldwide may be taken over by machines, while the need for a skilled workforce, particularly involving mathematics, computer science, and data science, in conjunction with multidisciplinary abilities across the sciences, social sciences, and humanities, (1)________ increasingly in greater demand. With climate change, increasing pollution, and depleting natural resources, there will be a sizeable shift in how we (2)_______ the world's energy, water, food, and sanitation needs, again resulting in the need for new skilled labour, particularly in biology, chemistry, physics, agriculture, climate science, and social science. The growing (3)________ of epidemics and pandemics will also (4)_______ collaborative research in infectious disease management and development of vaccines, and the resultant social issues heighten the need for multidisciplinary learning. There will be a growing (5)__________ for humanities and art as India moves towards becoming a developed country as well as among the three largest economies in the world.
Question:
Select the most appropriate option to fill in the blank number 3.
Option 1: wane
Option 2: dissolution
Option 3: emergence
Option 4: need
Correct Answer: emergence
Solution : The third option is the correct choice.
The context of the sentence suggests that there is something growing related to epidemics and pandemics. Emergence fits well in this context, indicating the increasing occurrence or appearance of epidemics and pandemics.
The meanings of the other options are as follows:
- Wane means to decrease, decline, or gradually diminish.
- Dissolution is the process of breaking up or termination, often used in the context of a group or substance.
- Need means a requirement or necessity.
Therefore, the correct answer is emergence.
