Directions (Q. )

In each of the following questions, a passage consists of six sentences. The first and sixth sentences are given at the beginning and end (as S₁ and S₆). The middle four sentences have been jumbled up and labelled as P, Q, R, and S. Find the proper sequence for the four sentences.

Question 26

Medium

A star's life is determined largely by its mass.
Heavy elements created in these explosions are scattered into space.
Massive stars burn their fuel rapidly and end their lives in dramatic supernova explosions.
Small stars like the Sun swell into red giants before shedding their outer layers.
This material later forms new stars, planets, and even living things.
Stars, in this sense, are the factories that build the chemical elements of the universe.

A PRSQ

B RQPS

C SPQR

D QSRP

Correct Answer: B

Explanation:

R describes the fate of small stars, Q describes massive stars and their supernovae, P describes the elements scattered by explosions, and S describes how this material forms new bodies.

Question 27

Medium

Ant colonies divide labour among workers with different roles.
Most workers forage for food, nurse the larvae, and maintain the nest.
The queen's main role is to lay eggs, while the colony depends on her for its survival.
Certain species even cultivate fungus, which they feed on and protect within the nest.
Some workers specialise as soldiers, defending the colony against intruders and predators.
Such division of labour makes ant colonies remarkably efficient.

A SPQR

B RSPQ

C QPSR

D PRQS

Correct Answer: C

Explanation:

Q describes the queen's role, P describes the roles of most workers, S describes soldiers, and R describes fungus farming by some species.

Question 28

Easy

Kites are among the oldest flying devices, with origins traced to ancient China.
Later, European scientists used kites to study the atmosphere and electricity.
Their shape and string allowed them to catch the wind efficiently.
Benjamin Franklin's famous experiment with a kite during a thunderstorm is one example.
Modern kites, made of lightweight fabrics, are now popular for sport and competition.
A simple design has therefore served both play and science for centuries.

A RSQP

B QPRS

C SRPQ

D PRQS

Correct Answer: B

Explanation:

Q explains why kites worked, P moves to their scientific use, R gives Franklin's experiment as an example of that use, and S describes modern kites.

Question 29

Medium

Honeybees communicate the location of food sources through a set of movements known as the waggle dance.
The duration of the waggle indicates distance, with longer runs signalling more distant sources.
A forager returns to the hive and performs a figure-eight run, waggling its abdomen in the middle.
The angle of the waggle relative to vertical indicates the direction of the food relative to the sun.
Other workers follow the dancer closely and sense the vibrations and scents carried on its body.
This dance allows the colony to exploit food sources it could never find alone.

A SRPQ

B QRPS

C PSQR

D RQSP

Correct Answer: B

Explanation:

Q describes the figure-eight run, R describes the direction, P describes the distance, and S describes how other workers follow.

Question 30

Easy

Flamingos are famous for their pink plumage, which comes from what they eat.
Flamingos in captivity lose their colour unless their diet includes carotenoid supplements.
They feed on algae and tiny crustaceans rich in pigments called carotenoids.
The pigments are processed by the liver and deposited into growing feathers.
Their pink colour is therefore a visible sign of a healthy diet.
Diet, in this way, shapes the appearance of many wild birds.

A RPSQ

B SQPR

C QRPS

D PSRQ

Correct Answer: C

Explanation:

Q describes the pigment-rich food, R describes how pigments reach the feathers, P describes captive flamingos losing colour, and S draws the conclusion about diet and health.
