Q.1-5. Read the following passage carefully and answer the questions given below it.
Scientists have discovered a previously unknown "supercolony" of more than 15,00,000 Adelie Penguins in the Danger Islands, a chain of remote, rocky islands off of the Antarctic Peninsula's northern tip. For the past 40 years, the total number of Adelie Penguins, one of the most common on the Antarctic Peninsula, has been steadily declining - or so biologists have thought. "Until recently, the Danger Islands weren't known to be an important penguin habitat," said the associate professor in the US.
These supercolonies have gone undetected for decades, partly because of the remoteness of the islands themselves, and partly the treacherous waters that surround them. Even in the austral summer, the nearby ocean is filled with thick sea ice, making it extremely difficult to access. Researchers arranged an expedition to the islands with the goal of counting the birds firsthand. When the group arrived in December 2015, they found hundreds of thousands of birds nesting in the rocky soil, and immediately started to tally up their numbers by hand. The team used a modified commercial quadcopter drone to take images of the entire island from above.
"The drone lets you fly in a grid over the island, taking pictures once per second. You can then stitch them together into a huge collage that shows the entire landmass in 2D and 3D. Once those massive images are available, the team can use neural network software to analyse them, pixel by pixel, searching for penguin nests autonomously.
Q.1. Why did the team use a modified commercial quadcopter drone?
(1) to take images of the entire island from above.
(2) to take images of the entire animal species from above.
(3) to take images of the entire island from above.
(4) to take images of the blizzard that occurs there rarely.
(5) All Except (1)

(1) Adelie Petrels
(2) Adelie Elephants
(3) Adelie Penguins
(4) Adelie Peasants
(5) Adelie Sparrows
Q.3. Why have supercolonies of the Penguins in the Danger Islands gone undetected for decades?
(A) because of the remoteness of the islands themselves
(B) because of the treacherous waters that surround them

(1) Only (A)
(2) Both (A) and (B)
(3) Only (C)
(4) All (A), (B) and (C)
(5) Only (B)
Q.4. Why did researchers arrange an expedition to the islands?
(1) with the goal of making the obscure island known.
(2) with the goal of counting the birds firsthand.
(3) with the goal of attracting the global financial leaders towards it.
(4) Both (1) and (3)
(5) Both (2) and (3)
Q.5. What is the ultimate motto of the team once the massive images available?
(1) The team can use neural network software to analyse them.
(2) The team can use the massive images to broadcast them.
(3) To search for penguin nests autonomously.
(4) To look into the “declining figures of polar beer” from the island.
(5) Both (1) and (2)
Q.6-10. Rearrange the following sentences (A),(B),(C), (D), (E) and (F) in the proper sequence to form a meaningful paragraph, then answer the questions given below them.
(A) Giving the appearance that the Sun is tilted slightly, researchers said. “Because Planet Nine is so massive and has an orbit tilted
(B) Compared to the other planets, the solar system has no choice but to slowly twist out of alignment,” said a graduate student in the US.
(C) The large and distant planet that was predicted to exist in January this year may be adding a wobble to the solar system,
(D) That plane, however, rotates at a six-degree tilt with respect to the Sun — giving the appearance that the Sun itself is
(E) All of the planets orbit in a flat plane with respect to the Sun, roughly within a couple degrees of each other.
(F) Cocked off at an angle. Until now, no one had found a compelling explanation to produce such an effect.
(G) The discovery of evidence that the Sun is orbited by an as-yet-unseen planet — that is about 10 times the size of Earth with an orbit.
(H) “It’s such a deep-rooted mystery and so difficult to explain that people just do not talk about it” said by the scientist.
