   For each Delta vacuum cleaner, the efficiency of its dust filtration system has a significant impact on

   Why this is right

   This answer connects the cleaning efficiency of a Delta vacuum with the efficiency of its dust filtration system.

   Skill tested: Sufficient Assumption · how this choice captures the argument's function is the move to repeat next time.

2. B

   Weakens10% picked this

   One can accurately infer how powerful a Delta vacuum cleaner's motor is from the efficiency of the vacuum

   This undermines the argument by questioning the argument's own support.

   All Delta vacuum cleaners that clean equally effectively have identically

   This addresses the wrong point. The argument is whether Delta vacuums with identically powerful motors clean with equal effectiveness.

4. D

   Weakens2% picked this

   For any two Delta vacuum cleaners with equally efficient dust filtration systems, the one with the more powerful

   This would only make it easier to predict how effectively a Delta vacuum cleans by determining how powerful the motor is.

5. E

   Out of Scope4% picked this

   One cannot accurately assess how effectively any Delta vacuum cleaner cleans without knowing how powerful that

   This is about assessing how effective the vacuum cleaner was rather than predicting how well it will clean. The issues are related but not the same; the former is about the past, while the latter is about the future.
