Two years ago, the state of Lonsia declared the goal of reducing the number of un-recycled soda cans to half. The un-recycled soda cans were about 10 per person then. Currently the soda cans that are un-recycled are only 5 per person. Clearly, the state has met its goal.
Type - assumption
Boil it down - suppose two years ago , total population was 10 and the number of un-recycled soda cans was 100 .
- What if the population has now increased to 20 , but the number of un-recycled soda cans is 100 . If this is true , then our claim will not hold water .
A) People are increasingly becoming aware of the harmful effects of drinking soda. - Irrelevant
B) There is little damage to the overall soft drink industry due to the negative publicity generated by the recycling campaign. - Irrelevant
C) Lonsia is not the only state that is concerned about recycling. - Irrelevant
D) The total population of the state of Lonsia has not increased substantially in the past two years. - Correct - negate this statement and the argument falls apart
E) The per-capita consumption of soda in the state of Lonsia has not increased during the past two years. ISWAT - even if per-capita consumption has increased of soda has increased , it does not matter since we are only concerned with the number of un-recycled soda cans.
