To evaluate the analyst's statement and select the most reasonable inference, let's break it down systematically.
The Analyst’s Statement:Factories with biofiltration technology show significantly lower pollution levels.
This remains true even when production rates increase.
This suggests biofiltration technology is more effective at controlling pollution than traditional systems.
The goal is to infer something logically consistent with this information, without overstepping what is explicitly or implicitly stated.
Analyzing the Answer Choices:(A) All factories will eventually adopt biofiltration technology to comply with future environmental regulations.
Too strong: The passage does not predict the future adoption of biofiltration technology by all factories, nor does it mention future environmental regulations. This is speculative and cannot be inferred from the given statement.
Eliminate.(B) Traditional filtration systems may not maintain effectiveness at higher production rates as effectively as biofiltration technology.
Reasonable inference: The statement implies that biofiltration performs better than traditional systems, even as production rates increase. This suggests that traditional systems might lose effectiveness at higher production rates, which makes this choice a logical inference.
Keep.(C) Biofiltration technology is less costly to maintain than traditional filtration systems.
Not mentioned: The analyst’s statement does not provide any information about the costs of maintenance for either biofiltration or traditional systems. This cannot be inferred.
Eliminate.(D) Factories not using biofiltration technology are the largest contributors to air pollution.
Too broad: While factories without biofiltration might produce more pollution, the analyst’s statement does not compare these factories’ contributions to those of other pollution sources. The statement focuses only on relative effectiveness, not on overall contributions to pollution.
Eliminate.(E) Increased production rates always lead to higher pollution levels.
Contradicted: The passage specifically states that factories using biofiltration technology maintain low pollution levels even when production rates increase. This directly contradicts the choice.
Eliminate.Correct Answer: (B)Traditional filtration systems may not maintain effectiveness at higher production rates as effectively as biofiltration technology.
