Reading Passage:

Among the natural resources which can be called upon in national plan for development possibly the most important is human labour without productive labour force including effective leadership and intelligent middle management no amount of foreign assistance or natural wealth can ensure successful development and modernization. One essential factor is usually overlooked or ignored. The forgotten factor is the role of women. Development will be handicapped as long as women remain second-class citizens uneducated without any voice in family or community decisions without legal or economic status married when they are still practically children and thenceforth producing one baby after another often only to see half of them die before they are of school age. We can enhance development by improving woman power by giving women opportunity to develop themselves.
