1. S₁: You might say that all through history there have been wars and that mankind has survived inspite of them.
S₆: Man has now discovered how to release the colossal forces locked up in the atom.

P: Now, if his purposes are those of destruction, each fresh advance in his mastery of nature only increases the danger from war, as, men learn to destroy one another in ever great numbers, from ever great distances, and in ever more varied and ingenious ways.
Q: He has learned to tap the hidden forces of our planet and use them for his purposes.
R: It has even developed and become civilised inspite of-them.
S: This is true, but unfortunately as part of his development man has enormously increased his power over nature.

2. S₁: She used to work at the desk next to mine in the office several years ago.
S₆: I am glad that their demands have been accepted.

P: But it must have been exasperating that a male sitting beside her was 'doing the same work as she was and being paid more.
Q: She is certain to be still there, in the same old brown suit and fur lined boots.
R: She was as kind as she was efficient.
S: Now she and all her friends have won their long campaign for the justice of equal pay to be recognised.

3. S₁: Yawning or its absence has been related to various clinical conditions.
S₆: It is in reality a releasing stimulus.

P: Interestingly, some clinicians claim that those with acute physical illness don't yawn until they are on the road to recovery.
Q: It can be a symptom of brain lesions, haemorrhage, motion sickness and encephalitis.
R: But what is currently known about yawning is essentially anecdotal, mostly because the yawn has not got the respect it deserves.
S: On the other hand, it has been reported that psychotics rarely yawn, except those suffering from brain damage.

4. S₁: In other words, grammar grows and changeg, and there is no such thing as correct use of English for the past, the present and the future.
S₆: All the words that man has invented are divided into eight classes, which are called parts of speech.

P: "The door is broke."
Q: Yet this would have been correct in Shakespeare's time.
R: Today, only an uneducated person would say, "My arm is broke."
S: For example, in Shakespeare's play Hamlet, there is the line.

5. S₁: He took two cigarettes from my case.
S₆: Then he continued to draw on it.

P: But when the fit of coughing was over, he replaced it between his lips.
Q: He lit one of them and placed it between the lips.
R: Then with a feeble hand he removed the cigarette.
S: Slowly he took a pull at it and coughed violently.

6. S₁: The role of the precious yellow metal is undergoing a dramatic change.
S₆: Again, it would not be an economic proposition to buy and sell gold ornaments as an instrument of investment as buying would be costlier and selling will be at a discount.

P: In developing countries like India, where gold is used mainly for ornaments, a distinct change in attitude is in the offing.
Q: Slowly, the use of gold in the form of ornaments will be on the decline and even if gold prices shoot up, women folk would not like to sell off their ornaments.
R: The yellow metal will soon be treated as an investment instrument.
S: The maxim, "Larger the gold reserves, richer the country" will not hold good for a long time.

7. S₁: Instantly, the full load yanked Gordy towards the side of the bridge.
S₆: Feeling a sharp burning sensation where the cable was speeding between his things, Gordy rose on tiptoe and as he did, the slithering coil of cable tightened around his left foot and yanked him over the railing.

P: But the pull of the cable was too much.
Q: He could hardly feel the cUble, slipping through his fingers, ripping off his gloves, and streaking over the railing like an escaping snake.
R: It smashed his hands hard against the top of the railing, causing a split - second feeling of fierce pain followed by numbness.
S: He held on to the cable; it had been hard work lifting it, and he did not want to have to start over again.

8. S₁: Nobody likes staying at home on a public holiday- especially if the weather is fine.
S₆: It was very peaceful in the cool grass-until we heard bells ringing at the top of the hill.

P: We had brought plenty of food with us and we got it out of the car.
Q: The only difficulty was that millions of other people had the same idea.
R: Now everything was ready so we sat down near a path at the foot of a hill.
S: We moved out of the city slowly behind a long line of cars, but at last we came to a quiet country road and, after sometime, stopped at a lonely farm.

9. S₁: In hunting and gathering societies people live in what anthropologists call "the seasonal round."
S₆: The circle is not broken into a line; the tribe does not stay in one place altering nature to suit the needs of the human settlement.

P: When the salmon are running, it comes to the stream; when the wild grasseg must be gathered, the band moves on again.
Q: The tribal band is delicately adjusted to nature.
R: It circulates through space in the rhythm of the seasons each year.
S: It moves through space with the flow of time.

10. S₁: American private lives may seem shallow.
S₆: This would not happen in China, he said.

P: Students would walk away with books they had not paid for.
Q: A Chinese journalist commented on a curious institution: the library.
R: Their public morality, however, impressed visitors.
S: But in general they returned them.
