1. Statement: Should India have no military force at all?
Arguments:
No. Other countries in the world do not believe in non-violence.
Clearly, India needs to have military force to defend itself against the threat of other military powers in the world. So, none of the arguments holds strong.
2. Statement: Should we scrap the 'Public Distribution System' in India?
Arguments:
Yes, Protectionism is over, everyone must get the bread on his/her own.
Yes. The poor do not get any benefit because of corruption.
The Public Distribution System is indeed necessary to provide basic amenities to the economically backward sections of population. So, argument I is vague. Also, if the Objectives of a system are not fulfilled because of corruption, then getting rid of the system is no solution. Instead, efforts should be made to end corruption and extend its benefits to the people for whom it is meant. So, argument II also does not hold,
3. Statement: Should higher education be completely stopped for some time?
Clearly, higher education is not the cause of unemployment. In fact, it has created greater job opportunities. So, argument II is vague. Also, higher education promotes the country's development. So, argument I holds.
4. Statement: Should there be reservation in Government jobs for candidates from single child family?
Arguments:
No. This is not advisable as the jobs should be offered to only deserving candidates without any reservation for a particular group.
Yes. This will help reduce the growing population in India as the parents will be encouraged to adopt single child norm.
The Government has already made provisions for reservation of jobs for the economically backward sections, which is a must. So, abolishing the practice of reservation altogether has no meaning. Thus, argument I is vague. Also, more reservations would lead to non-recruitment of many more deserving candidates. Besides, such a reservation, if implemented, will cater to the job requirements of only a small section of population and not a major part of it. So, argument II also does not hold strong.
5. Statement: Should children be legally made responsible to take care of their parents during their old age?
Arguments:
Yes. Such matter can only be solved by legal means.
Yes. Only this will bring some relief to poor parents.
Taking care of the parents is a moral duty of the children and cannot be thrust upon them legally, nor such a compulsion can ensure good care of the old people. So, none of the arguments holds strong.
This is an alternating addition series, with a random number, 21, interpolated as every third number. The addition series alternates between adding 3 and adding 4. The number 21 appears after each number arrived at by adding 3.
In this alternating repetition series, a random number, 33, is interpolated every third number into a simple addition series, in which each number increases by 2.
This is an alternating addition series with a random number, 4, interpolated as every third number. In the main series, 1 is added, then 2 is added, then 1, then 2, and so on.
