Question : Comprehension: Read the given passage and answer the questions that follow.
While there is no denying that the world loves a winner, it is important that you recognise the signs of stress in your behaviour and be healthy enough to enjoy your success. Stress can strike anytime, in a fashion that may leave you unaware of its presence in your life. While a certain amount of pressure is necessary for performance, it is important to be able to recognise your individual limits. For instance, there are some individuals who accept competition in a healthy fashion. There are others who collapse into weeping wrecks before an exam or on comparing mark sheets and finding that their friend has scored better.
Stress is a body's reaction to any demands or changes in its internal and external environment. Whenever there is a change in the external environment, such as temperature, pollutants, humidity, or working conditions, it leads to stress. In these days of competition, when a person makes up his mind to surpass what has been achieved by others, leading to an imbalance between demands and resources, it causes psycho-social stress. It is part and parcel of everyday life.
Stress has a different meaning depending on the stage of life you are in. The loss of a toy or a reprimand from the parents might create a stress shock in a child. An adolescent who fails the examination may feel as if everything has been lost and life has no further meaning. As an adult, the loss of his or her companion, job, or professional failure may appear as if there is nothing more to be achieved.
Such signs appear in the attitude and behaviour of the individual, such as muscle tension in various parts of the body, palpitation and high blood pressure, indigestion, and hyperacidity. Ultimately, the result is self-destructive behaviour such as eating and drinking too much, smoking excessively, and relying on tranquilisers. There are other signs of stress, such as trembling, shaking, nervous blinking, dryness of throat and mouth and difficulty swallowing. The professional under stress behaves as if he is a perfectionist. It leads to depression, lethargy, and weakness. Periodic mood shifts also indicate the stress status of the students, executives, and professionals.
Question: What does excessive stress NOT result in?
Option 1: Hypertension
Option 2: Indigestion
Option 3: Relaxation
Option 4: Palpitation
Correct Answer: Relaxation
Solution : The third option is correct.
According to the last paragraph of the passage, stress results in palpitation, hypertension (high blood pressure), and indigestion. Relaxation is not a result of stress, making it the appropriate choice.

Question : Find the total surface area of a sphere whose volume is $\frac{256}{3} \pi \;\text{cm}^3$.
Option 1: $48 \pi \;\text{cm}^2$
Option 2: $64 \pi \;\text{cm}^2$
Option 3: $38 \pi \;\text{cm}^2$
Option 4: $56 \pi \;\text{cm}^2$
Correct Answer: $64 \pi \;\text{cm}^2$
Solution : The volume of a sphere is $V = \frac{4}{3} \pi r^3$ where V is the volume and r is the radius of the sphere. Given that the volume of the sphere is $\frac{256}{3} \pi \;\text{cm}^3$. $⇒\frac{256}{3} \pi = \frac{4}{3} \pi r^3$ $⇒r =
