Question : Comprehension:

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:
What is the connection between the prize winners and the famous Indian mathematical genius Ramanujan?

Option 1: They explained Ramanujan's graphs in solving the Kadison-Singer problem.

Option 2: The prize winners were all admirers of Ramanujan's great contribution.

Option 3: The prize winners were all students of Ramanujan.

Option 4: They solved questions on Ramanujan's graphs that had not been solved for a long time.

Question : The following sentence has been split into four segments. Identify the segment that contains a grammatical error.

Option 1: for the computer

Option 2: to boot up

Option 3: a couple of minutes

Option 4: It is take

Question : Direction: Read the following passage and answer the questions given after it.
The science of climate change is more solid and widely agreed upon than you might think. But the scope of the topic, as well as rampant disinformation, can make it hard to separate fact from fiction. Here, we've done our best to present you with not only the most accurate scientific information but also an explanation of how we know it. Climate change is often cast as a prediction made by complicated computer models. But the scientific basis for climate change is much broader, and models are actually only one part of it (and, for what it's worth, they're surprisingly accurate).

For more than a century, scientists have understood the basic physics behind why greenhouse gases like carbon dioxide cause warming. These gases make up just a small fraction of the atmosphere but exert outsized control on Earth's climate by trapping some of the planet's heat before it escapes into space. This greenhouse effect is important: It's why a planet so far from the sun has liquid water and life! However, during the Industrial Revolution, people started burning coal and other fossil fuels to power factories, smelters and steam engines, which added more greenhouse gases to the atmosphere. Ever since human activities have been heating the planet.

Question:

For what duration of time, scientists learned the green house gases?

Option 1: more than a decade
 

Option 2: more than two fortnights
 

Option 3: more than a 20 years
 

Option 4: more than a century

Question : Under computerised accounting, procedure means:

Option 1: A logical sequence of actions to perform a task

Option 2: The raw fact (as input) for any business application

Option 3: User

Option 4: Computer, associated peripherals, and their network

Question : What is clickjacking?

Option 1: Malicious technique of tricking Web users into revealing confidential information.

Option 2: A device that sends and receives data in a bit second.

Option 3: A form of Computer Engineering.

Option 4: A digital process that is used to display an image on the monitor.
