Read the passage and answer the question. Why do zebras have stripes? Scientists have proposed many explanations, including camouflage, confusing predators and keeping cool. In recent years, the explanation with the strongest experimental support is that stripes discourage biting flies. In one study, flies landed far less often on horses wearing striped coats than on horses in plain coats. Flies seem to find it hard to slow down and land accurately on striped surfaces. Even so, researchers admit that stripes may serve more than one purpose. Which explanation of zebra stripes does the passage say has the strongest experimental support?

Read the passage and answer the question. Clownfish live among the stinging tentacles of sea anemones, which would kill most other small fish. A layer of mucus on the clownfish's skin protects it from the stings. The partnership benefits both animals: the anemone gives the clownfish a safe home, while the clownfish chases away fish that eat anemones and may provide the anemone with nutrients from its waste. Biologists call a relationship of this kind, in which both partners gain, mutualism. Which of the following is a benefit that the anemone receives?

Read the passage and answer the question. The kakapo of New Zealand is the world's heaviest parrot and one of its strangest. It cannot fly; instead it climbs trees and walks long distances at night. With no land mammals to fear for millions of years, the kakapo developed a simple defence: when danger approaches, it freezes and relies on its green feathers to blend in with the forest. This worked well against birds of prey that hunt by sight, but it was useless against the cats, rats and stoats brought by humans, which hunt by smell. By the 1990s only about fifty birds survived. In the passage, the word 'freezes' means ___.

Read the passage and answer the question. The axolotl is a type of salamander found in the wild only in a small area of lakes and canals near Mexico City. Unlike most amphibians, it usually never changes into an adult land animal. Instead, it keeps its feathery external gills and lives in water all its life, while still being able to breed. Axolotls are also famous for their ability to regrow lost limbs and even parts of some organs, which makes them of great interest to medical researchers. Sadly, the wild population has declined sharply because of pollution and the growth of the city. In the last sentence, what does 'declined sharply' mean?

Read the passage and answer the question. Elephants communicate not only with trumpeting calls but also with deep rumbles, many of which are too low in pitch for human ears to hear. These low-frequency sounds can travel several kilometres through the air and the ground. Researchers believe that elephants may detect some of these vibrations through sensitive nerve endings in their feet and trunks. This could help separated family groups to stay in touch and to coordinate their movements across large areas. How certain are researchers that elephants sense vibrations through their feet?
