- Option : B
- Explanation : The Montreal Protocol on Substances that Deplete the Ozone Layer (the Montreal Protocol) is an international agreement made in 1987. It was designed to stop the production and import of ozone depleting substances and reduce their concentration in the atmosphere to help protect the earth's ozone layer. Ozone mostly about 90% found in a layer that begins between 10 and 17 kilometers above the Earth's surface and extends up to about 50 kilometers. This region of the atmosphere is called the stratosphere.
27. Which among the following is least important for the academic success of students?
- Option : C
- Explanation : Cognitive competence is an essential requirement to attain academic success. Academic learning happens in a social environment; so, social competence is important; and since emotions are inseparable in social communication, emotional competence too is desirable.

- Option : A
- Explanation : The power of the source remains unaffected but, as the distance increases the intensity of noise from the source decreases and is inversely proportional to square of the distance from the source. Hence statement (A) is correct. Since sound pleasure of 2 pa correspond to sound level of 100 decibel. So statement C is wrong. Therefore option (A) is correct.
29. Which one of the following is true with respect to the first figure of categorical syllogism?
- A
The middle term is the subject of the major premise and the predicate of the minor premise
- B
The middle term is the predicate of the major premise and subject of the minor premise
- C
The middle term is the subject of the major premise and the predicate of the conclusion
- D
The middle term is the subject of the minor premise and the predicate of the conclusion
- Option : A
- Explanation : Categorical propositions can be of four
standard forms: A, E, I or O. A Syllogism
is made up of any three of these. Once a
syllogism is in standard form, its mood
and figure can be determined. The mood
and figure uniquely describe the form of
the syllogism. Any syllogism of this form
will have the same degree of validity or
invalidity.
Mood is a list of the three types of
propositions making up the syllogism
beginning with the major premise and
ending with the conclusion.
Figure depends on the arrangement of the
middle term in the two premises. There can
be four possible figures, easily remembered
by the flying brick shown below.
With the predicate and subject terms
introduced, the figures look as follows:
- Option : A
- Explanation : Reading data from the RAM is much faster than reading data from the hard drive. RAM can be accessed hundreds of times faster than a hard drive. In mathematics and computing, hexadecimal is a positional system that represents numbers using a base of 16. Decimal comes from the Latin word decimus, meaning tenth, from the root word decem, or 10. The decimal system, therefore, has 10 as its base and is sometimes called a base-I 0 system. 99 hexadecimal is equal to 153 decimal.
