In the following question, the 1st and the last part of the sentence/passage are numbered 1 and 6. The rest of the sentence/ passage is split into four parts and named P, Q, R and S. These four parts are not given in their proper order. Read the sentence/ passage and find out which of the four combinations is correct. 1.During a research experiment, a marine biologist placed a shark into a large holding tank and then released several small bait fish into the tank. P. Again, the shark quickly attacked.  This time, however, the shark slammed into the fibreglass divider and bounced off. Q. As you would expect, the shark quickly swam around the tank, attacked and ate the smaller fish. R. The marine biologist then inserted a strong piece of clear fibreglass into the tank, creating two separate partitions.She then put the shark on one side of the fibreglass and a new set of bait fish on the other. S. Eventually, about an hour into the experiment, the shark gave up. 6. The marine biologist then removed the fibreglass divider, but the shark didn’t attack.  The shark was trained to believe a barrier existed.
