Directions: Answer the given question based on the following passage.

How many Indian states touch the boundary of Punjab?

Punjab is a state of India, located in the northwestern part of the subcontinent. It is bounded by the Indian states of Jammu and Kashmir to the north, Himachal Pradesh to the northeast, Haryana to the south and southeast, and Rajasthan to the southwest and by the country of Pakistan to the west. Punjab in its present form came into existence on November 1, 1966, when most of its predominantly Hindi-speaking areas were separated to form the new state of Haryana. The city of Chandigarh, within the Chandigarh union territory, is the joint capital of Punjab and Haryana. The word Punjab is a compound of two Persian words, panj (“five”) and āb (“water”), thus signifying the land of five waters, or rivers (the Beas, Chenab, Jhelum, Ravi, and Sutlej). The word’s origin can perhaps be traced to panca nada, Sanskrit for “five rivers” and the name of a region mentioned in the ancient epic the Mahabharata. As applied to the present Indian state of Punjab, however, it is a misnomer: since the partition of India in 1947, only two of these rivers, the Sutlej and the Beas, lie within Punjab’s territory, while the Ravi flows only along part of its western border. The state of Punjab has also gained true recognition among all individuals due to the presence of forestry, tourism, agriculture, industries and minerals. Livestock is also one of the other key highlights of the state. However, the state of Punjab has scarcity of basic minerals and fuels. This is one of the prime factors behind the poor rate of industrial development. Agriculture has been always a strong point in the economy of the state. The state has indeed made a huge impact in the overall economy of the country as far as the production of wheat is concerned. A few of the agriculture-based industries associated with the state include paper, wood, beverages and food products.

Multiple choice

Which of the following can be made out from the second paragraph of the passage about Andrew's early life?

Directions: Read the following passage carefully and answer the questions by selecting the most appropriate options.

It was a sunny day in the month of May. The sun took its rightful position very early; lending credence to the general feeling that Andrew's birthday ceremony was going to be greeted with the blessing of a pleasant climate. The sky looked so bright that Andrew insisted on having an open air party. The habitual doubting Thomases had no dis­senting opinions to express. Andrew had gone to a great length to ensure a hitch-free party; a party which would remain the talk of the town. Although it was not intended to be free for all, a lot had been done to stamp the occasion on the memories of many people long afterwards.
The bright sun continued to smile. Andrew's face beamed with pleasure with every passing moment. Very few of his contemporaries have so succeeded in reaching the top of the ladder. Andrew in particular had been an orphan of storm. His father's death during his third year in the secondary school and that of his mother two years later were the only two of this orphan's `storms'. He suffered a physical misfortune when a machine severed his left middle finger. But Andrew did not despair.

The courage to fail is very cheap. Every fool can afford to fail. But it raises one above the herd of cowards and never-do-wells to be up and struggling. The reward of forbearance in the end is resounding success. And so it was for Andrew. Ever since he finished his university education, it had been success galore. He had got a good job in one of the country's insurance companies. His pay was good, his promotion had been steady and his prospects seemed bright. At forty, he had a good car and had already bought a house of his own. The world was at his feet!

 

  1. The loss of his parents was the only setback he had to face in his life.

  2. The loss of his middle finger in an accident was the severest of all the storms he had to face in his life.

  3. He had to face far too many misfortunes in his life including the loss of his parents

  4. Despite all the misfortunes, Andrew never gave up his hope.

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The second paragraph mentions Andrew's misfortunes (orphan of storm, parents' deaths, severed finger) but explicitly states 'But Andrew did not despair.' Option D correctly captures this resilience. Options A and B are wrong because he faced multiple setbacks beyond just parents' death or just the finger. Option C is incorrect because he specifically did NOT have 'far too many' - the text calls him 'an orphan of storm' and says those were 'the only two of this orphan's storms,' plus he overcame them.

Multiple choice

Which of the following is known as the real ozone killer?

Directions: Read the following passage carefully and answer the questions by selecting the most appropriate options.

We are today faced with a great ecological problem for which we ourselves are largely responsible. Our planet, the Earth, the only home of man is bathed in a steady rain of the sun's rays. Most of these rays supply us heat and light, but a small percentage is deadly. These are the ultraviolet - B rays (or UV - B). If these were to get to the surface of the Earth directly, they would kill us off. Luckily, the Earth’s surface is shielded from these rays by the ozone layer; but sadly enough this ozone layer is being destroyed by man.
The ozone layer is formed from a kind of oxygen with three atoms (O3) instead of the normal two (O2). Ozone oc­curs naturally in the stratosphere, several kilometres above the Earth's surface. It absorbs the dangerous UV -B rays but allows the much needed and safe light to pass through. There, in the stratosphere, it is constantly being created by the sun's rays; thus it is a self-repairing shield. But man is now gradu­ally destroying this vital shield with his industrial gases. The most lethal of these gases are the chlorofluorocarbons, or CFCs, which are used in making all kinds of foamed plastic products, propellants in spray cans, coolants in air condi­tioners and refrigerators and solvents to clean electronic equip­ment.

Down here, they are not lethal. But after they have leaked from air conditioners, plastic foam, cups, etc.; they slowly drift up to the stratosphere where, bombarded by ultraviolet rays, they break up at last, releasing chlorine, the real ozone killer. Sadly, one chlorine molecule may remain active for a century, destroying thousands of ozone molecules.

The black ant is regarded as one of the smallest insects on earth and

Directions: Read the following passage carefully and answer the questions by selecting the most appropriate options.

The black ant is indisputably one of the smallest visible insects on the earth. Except with the aid of a very powerful microscope, it is difficult, if not impossible, to locate the eyes, the mouth, the nostrils (if it ever has any) or any other part of its body. An air of mystery surrounds the existence of this little creature.

Have you ever taken time off your programme to watch these ants move in a row? What gives them the sense of direction, we do not know. Indeed, whoever sends them on an errand and how they even know the destination and the type of errand to run after are stories yet to be told. But they are an extremely well-organized lot.
Certainly, there are no defined routes for them on walls or trees, yet they move in an orderly manner, almost in a straight line. The beautiful thing about these insects is that, even when their line of movement is disorganized, they soon regroup and connect themselves again end to end. If in the process, one of them is killed, they quickly recognize that fact from their various positions. Then, one sees them run­ning helter-skelter with a seeming insistence on getting at the comrade to confirm its death.
When this has been done, some of them run zigzag at a tremendous speed to alert the others on the route. Soon, they disappear completely. Later, as if everything were over and forgotten, they reappear and .form a new route and continue their movement transporting food or going on one errand or the other as before. Bring your ears close to them and you hear nothing and you wonder what their means of communi­cation could be.
Perhaps, most surprising is their high sense of under­standing the weather and the climate. They are just like men in this area. They know when it is the rainy season and when the dry season comes. In fact, it is true to say that they prepare better for the future than man.

During the dry season, they file out to different places ­gathering food which they store underground. At the slightest sign of the approach of the rainy season, they all get into the hole and seal it up. Surprisingly, they re-emerge when the dry season sets in. Who tells them that the dry season has come, we do not know. You can now see the sense in the injunction, Go to the ant, thou sluggard, learn her ways and be wise.

A Correct answer
Explanation

The question asks for evidence that ants move 'in an orderly manner, almost in a straight line.' Option A directly supports this by stating that even when their line is disturbed, they regroup and connect 'end to end' - demonstrating their ability to restore orderly movement. Options B, C, and D describe reactions to a dead comrade, not the general orderly movement pattern.

Multiple choice

Which of the following is the most surprising thing about black ants?

Directions: Read the following passage carefully and answer the questions by selecting the most appropriate options.

The black ant is indisputably one of the smallest visible insects on the earth. Except with the aid of a very powerful microscope, it is difficult, if not impossible, to locate the eyes, the mouth, the nostrils (if it ever has any) or any other part of its body. An air of mystery surrounds the existence of this little creature.

Have you ever taken time off your programme to watch these ants move in a row? What gives them the sense of direction, we do not know. Indeed, whoever sends them on an errand and how they even know the destination and the type of errand to run after are stories yet to be told. But they are an extremely well-organized lot.
Certainly, there are no defined routes for them on walls or trees, yet they move in an orderly manner, almost in a straight line. The beautiful thing about these insects is that, even when their line of movement is disorganized, they soon regroup and connect themselves again end to end. If in the process, one of them is killed, they quickly recognize that fact from their various positions. Then, one sees them run­ning helter-skelter with a seeming insistence on getting at the comrade to confirm its death.
When this has been done, some of them run zigzag at a tremendous speed to alert the others on the route. Soon, they disappear completely. Later, as if everything were over and forgotten, they reappear and .form a new route and continue their movement transporting food or going on one errand or the other as before. Bring your ears close to them and you hear nothing and you wonder what their means of communi­cation could be.
Perhaps, most surprising is their high sense of under­standing the weather and the climate. They are just like men in this area. They know when it is the rainy season and when the dry season comes. In fact, it is true to say that they prepare better for the future than man.

During the dry season, they file out to different places ­gathering food which they store underground. At the slightest sign of the approach of the rainy season, they all get into the hole and seal it up. Surprisingly, they re-emerge when the dry season sets in. Who tells them that the dry season has come, we do not know. You can now see the sense in the injunction, Go to the ant, thou sluggard, learn her ways and be wise.

 

  1. They can always maintain a straight line of movement.

  2. During the dry season they file out to different places to gather food.

  3. They have a highly developed sense of understanding of the weather and climate.

  4. Black ants re-emerge from their hole when the dry season sets in.
