SECTION : A – READING (20 marks)
1. Read the passage given below and answer the questions that follow :
(10)
World’s Largest Marsupial
Which Australian mammal can leap 25 feet in one hop and move for short periods at
35 miles per hour? The Red Kangaroo. A full grown male stands as tall as a 6 ft.
person and weighs 200 pounds. This is slightly bigger than the grey kangaroo, making
it the world’s largest marsupial.
Marsupials are mammal where the mother has a pouch for carrying, feeding and
protecting her young one. While a red kangaroo may be the largest marsupial, the
new-born baby is tiny, under an inch long. After a few months of sleeping, nursing
and growing in mom’s stomach pouch the young kangaroo (joey) begins to come out,
but it hurries back to the pouch fast when frightened, hungry or cold. Eventually, the
joey gets so big it hangs out of the pouch. Then, at eight months old, it stays out. But
the joey remains close to mom until ready to live on its own.
Red kangaroos are good swimmers. However, they are best known for their hopping
abilities.
Their long, powerful hind legs have big feet. Hopping moves them quickly over their
grassy, shrubby and desert habitats. Meanwhile, a thick tail helps them balance and
steer.
What do red kangaroos eat? Grass, leaves and other vegetation. And guess what they
often regurgitate food and chew their cud just like a cow. The red kangaroo’s
vegetarian diet provides much of its water. It can also go long periods without
(14)
drinking. Staying in the shade, panting and limiting most activity to night time helps
the red kangaroo conserve water and stay cool.
Red kangaroos travel together in groups called Mobs. Mobs include both males and
females, with one male being dominant. Males show their dominance by “boxing”
with other males. They balance on their tails and try pushing each other off balance
with their forearms or by kicking their hind legs. This kicking ability, along with their
sharp claws, can also be used by kangaroos to defend against Australia’s wild dog,
the dingo.

More about people
When people aren't asking questions
They're making suggestions
And when they're not doing one of those
They're either looking over your shoulder or stepping on your toes
And then as if that weren't enough to annoy you
They employ you.
Anybody at leisure
Incurs everybody's displeasure.
It seems to be very irking
To people at work to see other people not working,
So they tell you that work is wonderful medicine,
Just look at Firestone and Ford and Edison,
And they lecture you till they're out of breath or something
And then if you don't succumb they starve you to death or something.
All of which results in a nasty quirk:
That if you don't want to work
You have to work to earn enough money so that you won't have to work.
