Organite is a kind of bioorganic fertilizer that is produced by harvesting wastewater from both households and industrial sources. The water is chemically treated at water reclamation facilities, where nutrients are extracted from the waste. These nutrients are then used to produce Organite, which has greatly decreased the need to produce synthetic nutrients. However, production of synthetic nutrients for fertilizers has increased by 60 percent over the last decade.
Which of the following, if true, most helps to explain the apparent discrepancy?
(A) Many farmers are not convinced that products created from recycled waste can be as effective as conventional methods of fertilizing crops.
(B) The production rate of bioorganic fertilizers is significantly lower than the growth rate of the overall market for fertilizers.
(C) Bioorganic products have been proven to be more successful than synthetic products in the process of fertilization.
(D) Bioorganic materials are increasingly finding uses in processes other than agricultural fertilization.
(E) Several nutrients can be extracted from sources other than wastewater from domestic and industrial sources.
Paradox:
Nutrients from waste water are used to produce Organite (bioorganic fertiliser), which has greatly decreased the need to produce synthetic nutrients.
However, production of synthetic nutrients for fertilizers has increased by 60 percent over the last decade.
(A) Many farmers are not convinced that products created from recycled waste can be as effective as conventional methods of fertilizing crops.
It doesn't explain why production of synthetic nutrients has increased by 60%. This can explain why production of synthetic nutrients has not decreased as much as expected, but not why it has increased.
(B) The production rate of bioorganic fertilizers is significantly lower than the growth rate of the overall market for fertilizers.
This says that the market is growing rapidly. So need for fertilisers is increasing. Hence, even if we are producing a lot more bioorganic fertiliser, production of synthetic nutrients could have increased a lot too. This helps resolve the paradox.
(C) Bioorganic products have been proven to be more successful than synthetic products in the process of fertilization.
This doesn't explain why we are producing more synthetic nutrients.
(D) Bioorganic materials are increasingly finding uses in processes other than agricultural fertilization.
This doesn't explain why we are producing more synthetic nutrients.
(E) Several nutrients can be extracted from sources other than wastewater from domestic and industrial sources.
Irrelevant to the argument.
Answer (B)
