(a) Inhalation inflates the alveoli (balloon like structures in the lungs)- there are between 300 million and 400 million alveoli in each lung.
(b) The pulmonary disease (emphysema), most common in long term smokers, result from an enlargement of the alveoli as some as destroyed and other enlarge or combine. Normally, it would take twice the pressure to inflate a membrane with twice the radius. The enlarged alveoli provide less recoil on exhalation, and a person with emphysema has difficulty in breathing as well as reduced oxygen exhange.
Smoking results in painful existence leading to death and hence should shunned at all costs.
(c ) In a newborn baby, the alveoli are small and collapsed and must be inflated with initial inhalation. The traditional practice is to accomplish this are slaps on the baby's bottom to make the newborn cry and inhale.

A social worker was addressing people at an eye donation camp organised in a colony. He said that there are millions of blind people in our country who cannot see at all. The eyesight of most of these blind people can be restored if we donate our eyes by making a pledge in writing to the eye bank that, after our death, our eyes should be removed and given to the blind people. He said, in this way we can pass on the priceless gift of vision to our blind brothers and sisters to light up their dark world, without losing anything. By listening to the social worker, many people (including some students) filled up the pledge forms to donate their eyes, after death. (a) Whitin how much time of the death of person, his donated eyes must be removed and preserved so as to remain good for transplantation ? (b) What happens to those donated eyes which are not good for transplanation ? (c) Can a person having AIDS disease donate eyes ? (d) Can a person having diabetes disease donate eyes ?

The man who is perpetually hesitating which of the two things he will do first, will do neither. The man who resolves, but suffers his resolution to be changed by the first counter-suggestion of a friend, who fluctuates from opinion to opinion, from plan to plan, and veers like a weather-cock to every point of the compass, with every breath of caprice that blows-can never accomplish anything great or useful. Instead of being progressive in any thing, he will be at best stationary, and more probably retrograde in all. It is only the man who first consults wisely, then resolves firmly, and then executes his purpose with flexible perseverance, undismayed by those petty difficulties which daunt a weaker spirit that can advance to eminence in any line. Take your course wisely, but firmly. and having taken it, hold upon it with heroic resolution, and the Alps and Pyrenees will sink before you. What will the man who sticks to his resolve and executes it advance to?

Following questions are based on poem given below: I heard a thousand blended notes While in a grove I sat reclined, In that sweet mood when pleasant thoughts Bring sad thoughts to the mind. To her fair works did Nature link The human soul that through me ran, And much it grieved my heart to think What man has made of Man. Through primrose tufts, in that sweet homer The periwinkle trailed its wreaths, And' tis my faith that every flower Enjoys the air it breathes. The birds around me hopped and played Their thoughts I cannot measure, - But the least motion which they made It seem'd a thrill of pleasure. The budding twigs spread out their fan To catch the breezy air, And I must think, do all I can That there was pleasure there If this belief from heaven be sent, If such be Nature's holy plan Have I not reason to lament What Man has made of Man ? What is the message that the poet wishes to convey in this poem? The poet wishes to say that
