Directions for questions 8 to 12: Read the passage and answer the questions that follow.
Wealth should not be an end in itself but only a means of satisfying one’s as well as others’ needs. It should
be a means of creating a happy and humane society. Riches can be profitably spent in removing the wants of
the poor and the needy, by providing them with food and clothing, by establishing hospitals for the sick,
shelters for children who have none to look after them, and old-age homes to provide comfort and company to
the growing number of old and helpless people. Wealth can also be put to public use by establishing trusts to
open up more and more educational institutions, to finance research work for promotion of science, health
care and agriculture. When used only as a means of creating more and more luxuries and procuring objects
of sensual gratification, it leads to corruption and sin. Even wealth used only to generate more wealth loses its
intrinsic worth. We should not forget that wealth came into existence to facilitate the fulfilment of human needs
and development of society.
8. By saying ‘Wealth should not be an end in itself’ the writer means that
(1) One should not stop creating wealth
(2) Creating more and more wealth should not be one’s object
(3) Wealth should not be used for personal use
(4) Wealth is exhausted if not used in different tasks
9. In Riches can be profitably spent’ the word ‘profitably’ in this context means
(1) Riches can be used in manifold ways
(2) Riches can be used for financial gains
(3) Riches can be used in beneficial way
(4) Riches can be used to acquire fame TCYonline.com Sample Questions (Verbal) 3

(4) Wealth should be used for others only after fulfilling one’s needs
11. The intrinsic worth of wealth lies in
(1) its use for charitable purposes
(2) its use for enjoyment of life
(3) its use for fulfilment of human needs and development of society
(4) its use for self-aggrandizement
