LR Question 19 Explanation

QUESTION TEXT: Some cleaning fluids, synthetic carpets, wall paneling…

QUESTION TYPE: Complete the Argument

ANALYSIS: The passage is leading up to the conclusion that houseplants can help reduce toxin levels in poorly ventilated homes. The stimulus implies that houseplants are able to remove toxins in general: formaldehyde was given as an example.

___________

1. We only have evidence that they remove formaldehyde. Besides, the stimulus was about more than Benzene.
2. We have no idea if this is even true.
3. We know that insulation traps heat and toxins. Houseplants remove toxins. We don’t know if they do anything to heat.
4. CORRECT. Yes. At least one study shows they remove toxins in poorly ventilated houses. This encompasses the entire stimulus.
5. The stimulus says that toxins are not a problem in well ventilated houses. It seems likely that houses with ventilation are at least as good as plants at keeping away toxins.
