Environment minister: Because of our concern about global warming, this country has committed itself to reducing its emissions of carbon dioxide substantially over the next ten years. Since trees absorb carbon dioxide, planting large numbers of trees will help us fulfil our commitment.

Which one of the following, if true, would most weaken the environment minister's argument?


(A) Owners of large tracts of private land are usually unwilling to plant trees unless they are given a financial incentive for doing so.

(B) Over the last ten years the proportion of land that is deforested annually has not increased as much as has the proportion of carbon dioxide in the atmosphere.

(C) When ground is disturbed in the course of planting trees, more carbon dioxide is released into the atmosphere by rotting organic matter in the soil than the new trees will absorb in ten years.

(D) Many climate researchers believe that global warming is such an urgent problem that carbon dioxide emissions should be substantially reduced in less than ten years.

(E) Gases other than carbon dioxide contribute to global warming, and trees do not absorb any of these other gases

Environment minister: Because of our concern about global warming, this country has committed itself to reducing its emissions of carbon dioxide substantially over the next ten years. Since trees absorb carbon dioxide, planting large numbers of trees will help us fulfil our commitment.

Understand:
Goal : Reduce CO2 substantially over next ten years
Plan : Plant tress = tress =CO@2 = CO2 reduce

Assumption : the plan itself will not ruin the efficacy !!
There will no relative increase in CO2 which will belie the effect of tree plantaion emission control

Which one of the following, if true, would most weaken the environment minister's argument?


(A) Owners of large tracts of private land are usually unwilling to plant trees unless they are given a financial incentive for doing so.
- DO we know that the govt. is willing to provide the incentive?? It may be or may not be - INCONCLUSIVE TYPE OF ANSWER

(B) Over the last ten years the proportion of land that is deforested annually has not increased as much as has the proportion of carbon dioxide in the atmosphere.
- STrengthener !! if deforrestation is lower than emission of CO2 then good right?

Quote:
(C) When ground is disturbed in the course of planting trees, more carbon dioxide is released into the atmosphere by rotting organic matter in the soil than the new trees will absorb in ten years.
- Destrosys the assumption !! e want to plant trees but if planting process worsens the plan even more then whats the use?? how ill we reduce the emission SUBSTANTIALLY !! Also the answer gives us a clear comparison that the emission of CO2 will be larger than what could be reduces in 10 years !! It acnnot get any more obvious !!!


(D) Many climate researchers believe that global warming is such an urgent problem that carbon dioxide emissions should be substantially reduced in less than ten years.
- What researchers beleive is of no use to us

(E) Gases other than carbon dioxide contribute to global warming, and trees do not absorb any of these other gases
- OUT of SCOPE ...
