Q:

Read the passage carefully and choose the best answer to each question out of the four alternatives.


Manja, or the glass-coated string used for flying kites, not only poses threat to humans, animals and birds but also to trees. A study by the country's oldest botanical garden has revealed that it poses a great threat to trees. But how can a snapped string struck in a tree kill the tree? Apparently, it does so by allying with the creepers in the garden.


A research paper by three scientists of the Acharya Jagdish Chandra Bose Indian Botanic Garden, located in West Bengal's Howrah district, illustrates in detail how the manja, in collusion with climbers, does the damage. "The abandoned, torn kite strings act as an excellent primary supporting platform for the tender climbers, giving easy passage to reach the top of the trees. Lateral branches from the top of the climber and other accessory branches from the ground reaches the top taking support of the first climber, completely covers the treetop, thus inhibiting the penetration of sunlight," says the research paper.


How many scientists contributed to a study by country's oldest botanical gardens on how manja can kill a tree?

 

A) Two B) Three
C) Five D) Four

Q:

Read the passage carefully and choose the best answer to each question out of the four alternatives.

"Tryst with Destiny" was a speech delivered by Jawaharlal Nehru, the first Prime Minister of independent India, to the Indian Constituent Assembly in Parliament, on 14th August 1947. It is considered to be one of the greatest speeches of all times and to be a landmark oration that captures the essence of the triumphant culmination of the largely non­violent Indian independence struggle against the British Empire in India.

"Long years ago we made a tryst with destiny, and now the time comes when we shall redeem our pledge, not wholly or in full measure, but very substantially. Freedom and power bring responsibility. The responsibility rests upon the assembly, a sovereign body representing the sovereign people of India. The service of India means the service of the millions who suffer. It means the ending of poverty and ignorance and disease and inequality of opportunity. We cannot encourage communalism or narrow­mindedness, for no nation can be great whose people are narrow in thought or in action.

To the people of India, whose representatives we are, this is no time for petty and destructive criticism, no time for ill will or blaming others. We have to build the noble mansion of free India where all her children may dwell".

What mansion did Nehru want to see built?

A) Nehru believed that the expensive mansion of India should be built. B) Nehru believed that the honorable mansion of India should be built.
C) Nehru believed that the simple mansion of India should be built. D) Nehru believed that the huge mansion of India should be built.
 
Answer & Explanation Answer: B) Nehru believed that the honorable mansion of India should be built.

Q:

Read the passage carefully and choose the best answer to each question out of the four alternatives.


Everyone expected Mary Zophres to win for her retro-revival Technicolor clothes in La La Land — the eventual winner, Colleen Atwood for Fantastic Beasts and Where to Find Them, seemed surprised too. But as other awards began to slip away from the well-reviewed musical, a theme could be teased out. What is Fantastic Beasts if not a plea for equal treatment of people, magical or otherwise? Then, Arrival, a film about the inherent benignity of aliens (read immigrants) won for Best Sound Editing. Hacksaw Ridge, which is, in a way, an anti-guns movie, won in two categories. Fences, about an African-American father who fears racial discrimination, took home the Oscar for Best Supporting Actress. Earlier, Moonlight, featuring two minority communities (black and gay), won for Best Supporting Actor. This turned out to be one of those years the Oscar voter was underestimated. As a majority of voters are actors, there was the tendency to think they'd reward La La Land, a celebration of creation: the heroine wants to make movies, the hero wants to make jazz. It looked like the year of The Artist all over again.

 

What does the lead female actor in La La Land want to do?

A) Make jazz B) Make movies
C) Make music D) Make magic
 
Answer & Explanation Answer: B) Make movies
