Statement : India today is midstream in its demographic transaction. In the last 60 years there has been an almost continuous decline in mortality; while fertility has declined over the last 20 years. The consequence is that there has been a rapid growth in population over the last 50 years.

Courses of Action :
I. India should immediately revitalise its family planning programme.
II. The Government should immediately launch a massive education programme through mass media highlighting the implication of population growth at the present rate.

A

Only I follows

B

Only II follows

C

Either I or II follows

D

Neither I nor II follows

E

Both I and II follow

In the following question, ashort passage with one of the lines in thepassage missing and represented by ablank is given. Select the best out of thefive answer choices given, to make thepassage complete and coherent(coherent means logically complete andsound).
There is a fairly universal sentiment thatthe use of nuclear weapons is clearlycontrary to mortality and that itsproduction probably so, does not go farenough. These activities are not onlyopposed to mortality but also to the law.If the legal objection can be added to themoral, the argument against the use andmanufacture of these weapons willconsiderably be reinforced. Now thetime is ripe to evaluate the responsibilityof scientists who knowingly use theirexpertise for the construction of suchweapons, which has a deleterious effecton mankind.
How appropriate it is that all thisvaluable skill should be devoted to themanufacture of weapons of death in aworld of poverty is a question that musttouch the scientific conscience.

A

Almost 50% of the skilled scientific\manpower in the world is now engaged\in the armaments industry.

B

To think that majority of the scientists\are promoting the manufacturing of the\armaments is hurtful.

C

Scientists should use their conscience\before taking up these contracts to\manufacture the weapons of mass\destruction.

D

Scientific manpower is used to the\interests of some selfish and careless\people who want to threaten the\existence of homo-sapiens.
