Option Analysis
(A) Although biodegradable plastic goods are now available, members of the town council believe biodegradable paper goods to be safer for the environment.
Negation Reason: This focuses on the council’s internal beliefs rather than the real-world outcome of the plan. A plan’s success is measured by its results, not the intentions of its creators.
The Trap: Focuses on "intent" rather than "efficacy."
Incorrect Part: "...members of the town council believe..."
(B) The paper factory at which most of the townspeople are employed plans to increase production of biodegradable paper goods.
Negation Reason: This describes a shift in the local economy that actually supports the plan by ensuring paper goods are readily available.
The Trap: This is a "Strengthener" or neutral context.
Incorrect Part: "...plans to increase production..." (This makes the plan easier to execute, not ill-suited).
(C) After other towns enacted similar bans on the sale of plastic goods, the environmental benefits were not discernible for several years.
Negation Reason: A delay in results does not mean the plan is fundamentally flawed or ill-suited; it just means the goal is long-term.
The Trap: Timeframe trap. GMAT logic dictates that a slow success is still a success.
Incorrect Part: "...not discernible for several years."
(D) Since most townspeople prefer plastic goods to paper goods in many instances, they are likely to purchase them in neighboring towns where plastic goods are available for sale.
Selection Reason: This identifies a "bypass" loophole. If the townspeople simply buy the plastic elsewhere and bring it back into the town, the amount of non-biodegradable waste isn't reduced. The plan fails to achieve its primary objective.
The Trap: None. It highlights a fatal flaw in the plan's logic.
(E) Products other than those derived from wood pulp are often used in the manufacture of paper goods that are entirely biodegradable.
Negation Reason: This provides information about how paper is made, but since the end product is still "entirely biodegradable," it doesn't hurt the council's goal.
The Trap: Irrelevant detail/Out of Scope.
Incorrect Part: "Products other than those derived from wood pulp..."
Correct Answer: (D)
