Question type:
Inference
In inference we look for a must be true statement based on the passage.
Answer choice analysis:
A. All factories will eventually adopt biofiltration technology to comply with future environmental regulations.
Incorrect, Based on data about present event we can just speculate what can and can not happen in the future, this will never form a must be true statement.
B. Traditional filtration systems may not maintain effectiveness at higher production rates as effectively as biofiltration technology.
correct, Nice and conservative language it actually captures the essence of what the argument says and acts as a valid rational conclusion let’s keep this for a while.
C. Biofiltration technology is less costly to maintain than traditional filtration systems.
Incorrect, Nowhere in the passage anything is mentioned about cost it is only talking about efficiency.
D. Factories not using biofiltration technology are the largest contributors to air pollution.
Incorrect. We have no data about the largest producers of air pollution maybe they are factories maybe automobiles.
E. Increased production rates always lead to higher pollution levels.
Incorrect. Beware of answer choices that use extreme words such as all, always, etc. Here just by data about few factories we can’t extrapolate and apply this as a generalization.
B is the answer
