1. Read the given text carefully and answer the following questions. [5]
Today scientists describe the universe in terms of two basic partial theories- the general theory of relativity and quantum mechanics, the great intellectual achievements of the first half of this century. The general theory of relativity describes the force of gravity and the large-scale structure of the universe, that is, the structure on scales from only a few miles to as large as a million million million million (1 with twenty-four zeros after it) miles, the size of the observable universe, Quantum mechanics, on the other hand, deals with phenomena on extremely small scales, such as a millionth of a millionth of an inch. Unfortunately, however, these two theories are known to be inconsistent with each other - they cannot both be correct. One of the major endeavors in physics today is the search for a new theory that will incorporate them both - a quantum theory of gravity. We do not yet have such a theory, and we may still be a long way from having one, but we do already know many of the properties that it must have.
1. What is the general theory of relativity?
2. What is the quantum mechanics?
3. What do you understand by a quantum theory of gravity that scientists are in quest for today?

What is the general theory of relativity?
The general theory of relativity describes the force of gravity and the large-scale structure of the universe. It specifically deals with phenomena on scales ranging from a few miles to the size of the observable universe.

What is quantum mechanics?
Quantum mechanics deals with phenomena on extremely small scales, such as a millionth of a millionth of an inch. It is a theoretical framework in physics that describes the behavior of matter and energy at the atomic and subatomic levels.

What do you understand by a quantum theory of gravity that scientists are in quest for today?
A quantum theory of gravity is a theoretical framework that physicists are seeking to develop in order to reconcile the general theory of relativity and quantum mechanics. Currently, these two fundamental theories in physics are known to be inconsistent with each other. The quest for a quantum theory of gravity aims to integrate both theories into a single, cohesive framework that can accurately describe both the very large-scale structure of the universe and the extremely small-scale phenomena at the quantum level.

4. What is the true measure or the danger or modern pollutants? "(Science and Survival)"
5. Why was Giordano Bruno burnt at the stake?"(Man and Nature) "
3. Remove possible ambiguities in the following sentences by changing the position of faulty modifiers. [5]
1. Mohan only scored ten runs.
2. He promised when a vacancy occurred to consider me for the position.
3. He found a dog in the boat, which was dark brown in color with a white tail.
4. A car came down the street decked with flowers.
5. The car is in the garage which he smashed.

a. Mohan scored only ten runs.
b. When a vacancy occurred, he promised to consider me for the position.
c. In the boat, he found a dark brown dog with a white tail.
d. Decked with flowers, a car came down the street.
e. The car which he smashed is in the garage.
4. Put the following sentences in the right order, so that they read like a coherent paragraph: [5]
1. Ten miles further down, the water is pure again.
2. This overwhelming kind of pollution is called super-pollution.
3. But if large quantities of sewage are dumped continuously, the purifying bacteria are killed 'and the stream loses its power to purify,
4. If sewage is dumped into a stream in small quantities, the stream dissolves it and purifies it.

"If sewage is dumped into a stream in small quantities, the stream dissolves it and purifies it. But if large quantities of sewage are dumped continuously, the purifying bacteria are killed, and the stream loses its power to purify. This overwhelming kind of pollution is called super-pollution. Ten miles further down, the water is pure again."
