abhijit_s_2000 Posted June 25, 2007 Share Posted June 25, 2007 Hi, I need a strategy to solve the questions of the type mentioned below. I would really appreciate if someone could offer me tips in identifying pattern fr strengthen/weaken argument questions: Most disposable plastic containers are now labeled with a code number (from 1 to 9) indicating the type or quality of the plastic. Plastics with the lowest code numbers are the easiest for recycling plants to recycle and are thus the most likely to be recycled after use rather than dumped in landfills. Plastics labeled with the highest numbers are only rarely recycled. Consumers can make a significant long-term reduction in the amount of waste that goes unrecycled, therefore, by refusing to purchase those products packaged in plastic containers labeled with the highest code numbers. Which one of the following, if true, most seriously undermines the conclusion above? (A) The cost of collecting, sorting, and recycling discarded plastics is currently higher than the cost of manufacturing new plastics from virgin materials. (B) Many consumers are unaware of the codes that are stamped on the plastic containers. © A plastic container almost always has a higher code number after it is recycled than it had before recycling because the recycling process causes a degradation of the quality of the plastic. (D) Products packaged in plastics with the lowest code numbers are often more expensive than those packaged in the higher-numbered plastics. (E) Communities that collect all discarded plastic containers for potential recycling later dump in landfills plastics with higher-numbered codes only when it is clear that no recycler will take them.

shekharbanka Posted June 26, 2007 Share Posted June 26, 2007 B for me. What's the OA? Quote Link to comment Share on other sites More sharing options...
monu123 Posted June 26, 2007 Share Posted June 26, 2007 IMO A...if recycling is costly then even if consumers stop buying high numbered plastics, intead of recycling manufacturers would prefer new plastics Quote Link to comment Share on other sites More sharing options...
cjoy Posted June 26, 2007 Share Posted June 26, 2007 IMO C. As per ©, more we recycle plastics more it gets unrecyclable (if there is a word like this :-) ). This means -> Even if the consumer buys a plastic container of lower code now, after recycling the same plastic will become less suitable for recycling and code associated with it will increase. Soon the recycled plastic will reach its end of life (state when it has to be disposed in landfills) and will no longer be usable. This would mean that irrespective of people making a selection for plastic with lower code after recycling the plastic will get degraded and the purpose of this strategy will fail.

Otori Takeo Posted June 26, 2007 Share Posted June 26, 2007 The intension for codifying plastic is to prohibit customers to use. However if pricing is not the same, this can weaken the intension. D is the best.. Quote Link to comment Share on other sites More sharing options...
aru4912 Posted June 26, 2007 Share Posted June 26, 2007 IMO C. The explanation mentioned by cjoy holds good for me too .. by the way what is the OA abhijit ? Quote Link to comment Share on other sites More sharing options...
