The City Social Work Club organized a bicycle rally in the city from The City Circle to the Edge Road. The
participants were mostly young members of the club. The rally was aimed at promoting awareness about
pollution in general and vehicular pollution in particular. The concept of the rally was to bring homo the
idea that the humble bicycle is not only a non-polluting means of transport but also worked wonders (or
one's health. I he rally culminated in a street play which emphasized the causes of motor vehicular
pollution and its effect on health. Which of the following statements is the most suitable assumption of the
organizers?

• A. Environment pollution can be controlled
• B. we need a pollution free environment and a healthy lifestyle
• C. Young people can influence the society
• D. consciousness about environment pollution needs to be increased
• E. Actions speak louder than words.

Most economists in the United States seem captivated by spell of the free market. Consequently, nothing
seems good or normal that does not accord with the requirements of the free market.
A price that is determined by the seller or for that matter, established by anyone other than the aggregate
of consumers seems pernicious, Accordingly, it requires a major act of will to think of price fixing (the
determination of prices by the seller) as both "normal" and having a valuable economic function. In fact,
price-fixing is normal in all industrialized societies because the industrial system itself provides, as an
effortless consequence of its own development, the price-fixing that requires, Modern industrial planning
requires and rewards great size. Hence a comparatively small number of large firms will be competing for
the same group of consumers. That each large firm will act with consideration of its own needs and thus
avoid selling its products for more than its competitors charge is commonly recognized by advocates of
free-markets economic theories. But each large firms will also act with full consideration of the needs that
it has in common with the other large firms competing for the same customers. Each large firm will thus
avoid significant price cutting, because price cutting would be prejudicial to the common interest in a
stable demand for products. Most economists do not see price-fixing when it occurs because they expect
it to be brought about by a number of explicit agreements among large firms; it is not.
More over those economists who argue that allowing the free market to operate without interference is the
most efficient method of establishing prices have not considered the economies of non socialist countries
other than the United States. These economies employ intentional price-fixing usually in an overt fashion.
Formal price fixing by cartel and informal price fixing by agreements covering the members of an industry
are common place. Were there something peculiarly efficient about the free market and inefficient about
price fixing, the countries that have avoided the first and used the second would have suffered drastically
in their economic development. There is no indication that they have.
Socialist industry also works within a frame work of controlled prices. In early 1970's, the Soviet Union
began to give firms and industries some of the flexibility in adjusting prices that a more informal evolution
has accorded the capitalist system. Economists in the United States have hailed the change as a return to
the free market. But Soviet firms are no more subject to prices established by free market over which they
exercise little influenced than are capitalist firms.

• C. radiation pressure decreases when a star's fuel has been consumed
• D. the collapse of a star increases its gravitational force.

Six people working in a company P, Q, R, S, T and U apply for getting posted out from their present

waiting list and will be posted in the order in which they appear on that list.
Postings are subject to the following constraints:
No more than three employees can be posted immediately.
U can be posted neither before P is posted nor before Q is posted.
If S is assigned to the waiting list, T must also be assigned to the waiting list.
R must be on the waiting list.
Which of the following could be a complete and accurate list of the people who are not posted in the order
in which they initially appear on the waiting list?

• A. R,T
• B. R,P,U,S
• C. U,S,T
• D. U,R,P
• E. P,T,U,R
