Question 23 : The passage given below is followed by four alternate
summaries. Choose the option that best captures the essence of the
passage.
Gradually, life for the island's birds is improving. Antarctic prions and
white-headed petrels, which also nest in burrows, had managed to cling on in some sites while
pests were on the island. Their numbers are now increasing. "It's fantastic and so exciting,"
Shaw says. As birds return to breed, they also poo. This adds nutrients to the soil, which in
turn helps the plants to grow back stronger. Tall plants then help burrowing birds hide from
predatory skuas. "It's this wonderful feedback loop," Shaw says. Today, the "pretty paddock"
that Houghton first experienced has been transformed. "The tussock is over your head, and you're
dodging all these penguin tunnels," she says. The orchids and tiny herb that had been protected
by fencing have started turning up all over the place.
The given paragraph describes how, in the absence of pests, birds have returned
to breed, plants have started growing back stronger and the ecosystem in general has become
transformed for the better in the island. Option B is the best of the given summaries.
Option A is incorrect. According to the paragraph, pests 'were' on the island, but are no longer
there.
The paragraph does not say the island has been 'brought under environmental
protection'. So, option C is incorrect.
The paragraph does not specifically say the
island in question is an Antarctic island. So, option D is incorrect.
Choice B is the correct answer.
