Question 1

Time: 00:00:00
Studies of the Weddell seal in the laboratory have described the physiological mechanisms that allow the seal to cope with the extreme oxygen deprivation that occurs during its longest dives, which can extend 500 meters below the ocean’s surface and last for over 70 minutes. Recent field studies, however, suggest that during more typical dives in the wild, this seal’s physiological behavior is different. In the laboratory, when the seal dives below the surface of the water and stops breathing, its heart beats more slowly, requiring less oxygen, and its arteries become constricted, ensuring that the seal’s blood remains concentrated near those organs most crucial to its ability to navigate underwater. The seal essentially shuts off the flow of blood to other organs, which either stop functioning until the seal surfaces or switch to an anaerobic (oxygen-independent) metabolism. The latter results in the production of large amounts of lactic acid which can adversely affect the pH of the seal’s blood, but since the anaerobic metabolism occurs only in those tissues which have been isolated from the seal’s blood supply, the lactic acid is released into the seal’s blood only after the seal surfaces, when the lungs, liver, and other organs quickly clear the acid from the seal’s bloodstream.

Recent field studies, however, reveal that on dives in the wild, the seal usually heads directly for its prey and returns to the surface in less than twenty minutes. The absence of high levels of lactic acid in the seal’s blood after such dives suggests that during them, the seal’s organs do not resort to the anaerobic metabolism observed in the laboratory, but are supplied with oxygen from the blood. The seal’s longer excursions underwater, during which it appears to be either exploring distant routes or evading a predator, do evoke the diving response seen in the laboratory. But why do the seal’s laboratory dives always evoke this response, regardless of their length or depth? Some biologists speculate that because in laboratory dives the seal is forcibly submerged, it does not know how long it will remain underwater and so prepares for the worst.

The passage provides information to support which of the following generalizations?

But why do the seal’s laboratory dives always evoke this response, regardless of their length or depth? Some biologists speculate that because in laboratory dives the seal is forcibly submerged, it does not know how long it will remain underwater and so prepares for the worst.

It can be inferred from the passage that by describing the Weddell seal as preparing “for the worst” (line 41), biologists mean that it.

Question 5

Time: 00:00:00
Read the passage given below and answer the question that follow.
Spring was the season of green mountain and meadows, blushing snow and an expanse of yellow
mustard flowers in the fields around our village. On radio Kashmir, they played songs in kashmir
celebrating the flowers in the meadows and the nightingales on willow branches. My favorite song
ended with the refrain:’And the night angle sings to the flowers: Our land is a garden!’. When we had
to harvest a crop, our neighbors and friends would send someone for help; when it was their turn, we
would reciprocate. You never needed to make a formal request weeks in advance, somebody always
turned up.
During the farming season, Akhoon, the mullah, who refused to believe that Neil Armstrong had
landed on the moon, complained about the thinning attendance at our neighborhood mosque. I
struggled to control my laughter when the villagers, anxious to get back to farming, coughed during
the prayers to make him finish faster. He compromised by reading shorter chapters from the holy
book and them turning up at the fields to collect a seasonal donation--his fees for leading prayers at
the mosque.

In summer, after the mustard was reaped, we planted rice seedlings. On weekdays, before we left for
school, my brother and I took samovers of kahwa, the sweet brew of saffron, almonds, and cinnamon,
to the laborers working in our fields. On weekends, I would help grandfather and other men carry
sacks of seedlings from the nurseries; my mother, aunts, and other neighboring women bent in rows
in the well-watered fields, planted and sang.

Question 8

Time: 00:00:00
Read the passage given below and answer the questions that follow:
I recently sent a message to my boss to let him know that I would be a bit late. The bus hadn’t arrived
despite a 30-minute wait in the freezing cold. To illustrate, I added an emoji of a snowflake and a
snowman from my iphone and sent them to his Android phone. Thankfully, those emoji didn’t get lost
in translation, but I panicked for a second wondering whether they’d appeared as a love heart or a
poop on his phone.
The reason I panicked is that just a few weeks ago I had spent far too much of my time creating a
story made completely from emoji, which I sent a group of friends via facebook messenger. Not one
of those friends replied to say how awesome my story was( and it really was awesome) and I soon
discovered why: on their Android smartphone it made absolutely no sense whatsoever because the
emoji were all different! I was devastated.
