The passage below is accompanied by four questions. Based on the passage, choose the best answer for each question
Landing in Australia, the British colonists weren’t much impressed with the small-bodied, slender-snooted marsupials called bandicoots. “Their muzzle, which is much too long, gives them an air exceedingly stupid,” one naturalist noted in 1805. They nicknamed one type the “zebra rat” because of its black-striped rump.
Silly-looking or not, though, the zebra rat—the smallest bandicoot, more commonly known today as the western barred bandicoot—exhibited a genius for survival in the harsh outback, where its ancestors had persisted for some 26 million years. Its births were triggered by rainfall in the bone-dry desert. It carried its breath-mint-size babies in a backward-facing pouch so mothers could forage for food and dig shallow, camouflaged shelters.
Still, these adaptations did not prepare the western barred bandicoot for the colonial-era transformation of its ecosystem, particularly the onslaught of imported British animals, from cattle and rabbits that damaged delicate desert vegetation to ravenous house cats that soon developed a taste for bandicoots. Several of the dozen-odd bandicoot species went extinct, and by the 1940s the western barred bandicoot, whose original range stretched across much of the continent, persisted only on two predator-free islands in Shark Bay, off Australia’s western coast.
“Our isolated fauna had simply not been exposed to these predators,” says Reece Pedler, an ecologist with the Wild Deserts conservation program.
Now Wild Deserts is using descendants of those few thousand island survivors, called Shark Bay bandicoots, in a new effort to seed a mainland bandicoot revival. They’ve imported 20 bandicoots to a preserve on the edge of the Strzelecki Desert, in the remote interior of New South Wales. This sanctuary is a challenging place, desolate much of the year, with one of the world’s most mercurial rainfall patterns—relentless droughts followed by sudden drenching floods.
The imported bandicoots occupy two fenced “exclosures,” cleared of invasive rabbits (courtesy of Pedler’s sheepdog) and of feral cats (which slunk off once the rabbits disappeared). A third fenced area contains the program’s Wild Training Zone, where two other rare marsupials (bilbies, a larger type of bandicoot, and mulgaras, a somewhat fearsome fuzzball known for sucking the brains out of prey) currently share terrain with controlled numbers of cats, learning to evade them. It’s unclear whether the Shark Bay bandicoots, which are perhaps even more predator-naive than their now-extinct mainland bandicoot kin, will be able to make that kind of breakthrough.
For now, though, a recent surge of rainfall has led to a bandicoot joey boom, raising the Wild Deserts population to about 100, with other sanctuaries adding to that number. There are also signs of rebirth in the landscape itself. With their constant digging, the bandicoots trap moisture and allow for seed germination so the cattle-damaged desert can restore itself.
They have a new nickname—a flattering one, this time. “We call them ecosystem engineers,” Pedler says.

Question: 1

Which one of the following options does NOT represent the characteristics of the western barred bandicoot?

Updated On: Nov 29, 2024
  • Long thin nose, black striped back, pouch for joeys
  • Shallow diggers having an elongated muzzle
  • Smallest black striped marsupial that uses camouflage and dig
  • Look of a rat but with a baby pouch and a slender snout

The Correct Option is C

Solution and Explanation

Option 3 does not accurately describe the western barred bandicoot. The passage describes the western barred bandicoot as small, with a long thin nose and a pouch for carrying babies, but does not mention it as the smallest black striped marsupial or as one that ”uses camouflage and digs” in such a way. Therefore, it is the odd one out.

Question: 2

The text uses the word ‘exclosures’ because Wild Deserts has adopted a measure of

Updated On: Nov 29, 2024
  • restoring cattle damaged deserts to green landscapes.
  • excluding animals to make the islands predator-free.
  • barring the entry of invasive species.
  • ridding the main desert of feral cats and large bilbies.

The Correct Option is C

Solution and Explanation

The term ”exclosures” refers to areas that are enclosed to prevent unwanted animals from entering. In the context of the passage, it is used to keep out invasive species like rabbits and feral cats, which is essential for the survival of the bandicoots.

Question: 3

Which one of the following statements provides a gist of this passage?

Updated On: Nov 29, 2024
  • The onslaught of animals, such as cattle, rabbits and housecats, brought in by the British led to the extinction of the western barred bandicoot
  • The negligent attitude of the British colonists towards these bandicoots evidenced by the names given to them led to their annihilation.
  • A type of bandicoots was nearly wiped out by invasive species but rescuers now pin hopes on a remnant island population.
  • Marsupials are going extinct due to the colonial era transformation of the ecosystem which also destroyed natural vegetation.

The Correct Option is C

Solution and Explanation

Statement 3 accurately summarizes the passage by focusing on the near extinction of the western barred bandicoot due to invasive species and the efforts to revive the population using the remnant island survivors.

Question: 4

According to the text, the western barred bandicoots now have a flattering name because they have

Updated On: Nov 29, 2024
  • aided in altering an arid environment.
  • led a revival in preserving the species.
  • led to a surge and increase of rainfall.
  • grown fivefold in terms of population.

The Correct Option is A

Solution and Explanation

The term “ecosystem engineers” is used to describe the bandicoots because their digging helps trap moisture, allowing for seed germination and the restoration of the cattle-damaged desert. This positive impact on the environment is why they are now referred to with this flattering name.
