Which word in the passage is a synonym of 'deadly'?

Directions: Read the following passage to answer the given question.

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.

Which of the following is an unpleasant thing that responsible parents often do?

Directions: Read the following passage to answer the given question.

Every child, whether he comes to his family by birth or adoption, discovers what a family is, through the experi­ences of family life. The new-born infant has no way of know­ing which of the many faces that hover above him belongs to a parent. He has no way of knowing what a parent is. He only knows that he is comfortable or uncomfortable, hungry or satisfied.
Gradually, as the months go by, he begins to know who brings comfort when he is uncomfortable and food when he is hungry. He comes to know the feel of the arm that holds him close when he eats and holds him safe in his bath. He grows to know who responds to his needs when he cries out, who is the special person in the whole strange new world who belongs specially to him. This is his first recognition of a parent.
The mother and the father who care for a child, who listen for his voice and try to interpret what he means, who com­fort him, feed him and play with him discover for the first time what it is to be parents. They do not become parents by virtue of conception and birth alone. They grow to be parents just as the infant grows to recognize them as such. They come to know the developing personality of their child in a way that no other person really can. They recognise whether he is a lusty eater or a nibbler, vivacious or reserved, adventurous or cautious. By observing his intellectual and physical abili­ties, they also get to know what he may become in future. They are concerned with meeting his needs and wants, and fostering his growth to maturity.

Sometimes, because of their responsibility to their child, parents have to do unpleasant things. They have to, for instance, take him for injections. He can have no choice about taking medicine when he is ill. He must learn quickly, and not neces­sarily at his own pace, that fire is not a play-thing. In the intimacies of daily living, the child and the parents learn the bitter and the sweet of family relations. It is through the experiences of family life that a child and his parents grow to be a family. For every parent, biological or adoptive, it is the daily loving care of the child and his responsiveness that build up the parents' feelings. When the child feels, it is being loved and being cared for, it produces family closeness.

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-organised 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."
