  • The political system always dominates the entire social scene and hence those who wield political power are generally able to control all the different social sub-systems and manipulate them to their own advantage. The social groups in power therefore have always manipulated the education systems, especially when these happen to depend upon the state for their very existence to strengthen and perpetuate their own privileged position. But here in lies a contradiction. For the very realisation of their selfish ends, the social groups in power are compelled to extend the benefits of these educational systems to theunder-privileged groups also. The inevitable task is generally performed with three precautions abundantly taken care of: One, the privileged groups continue to be the principal beneficiaries of the educational system, dominate the higher stages of education or the hard core of prestigious and quality institutions or the most useful of courses, so as to safeguard their dominant position of leadership in all walks of life. Second, the system is so operated that under-privileged groups can utilise it only marginally in real terms and the bulk of them become either dropouts or pushouts and get reconciled to their own inferior status in society. Third, the few from the weaker section that survive and succeed in spite of all the handicaps are generally co-opted within the system to prevent' dissatisfaction. Which is the best explanation as to why the few from the weaker section that survive and succeed inspite of all the handicaps are generally co-opted within the system?

    A
    To prevent the revolt in the society
    B
    To satisfy their instinct
    C
    To augment the position of the privileged class
    D
    All of the above
