Recycled plastic lumber is a building material made from plastic bottles and other plastic waste. Unlike traditional lumber, it won't rot or absorb water, and it is highly resistant to insect damage, so it is well-suited for marine and outdoor applications. Recycled plastic lumber is worth considering as an alternative to traditional lumber for most building projects, with the exception of interior residential projects.

Which of the following, if true, most helps to explain the exception noted above?


A. Residential homes built entirely with recycled plastic lumber are virtually immune to damage from flooding.

B. Increased rates of thermal expansion and contraction of plastic lumber can cause doorways constructed of this material to warp and either fail to close or fail to seal tightly.

C. Currently 25 percent of the trash that is in landfills is plastic that could be used to produce recycled plastic lumber.

D. Because of its resistance characteristics, recycled plastic lumber does not need to be treated with chemicals, allowing homeowners to live in an interior space with lower levels of chemicals.

E. Seldom painted, plastic lumber comes in different colors that can be chosen by the consumer.

Recycled plastic lumber is a building material made from plastic bottles and other plastic waste. Unlike traditional lumber, it won't rot or absorb water, and it is highly resistant to insect damage, so it is well-suited for marine and outdoor applications. Recycled plastic lumber is worth considering as an alternative to traditional lumber for most building projects, with the exception of interior residential projects.

Which of the following, if true, most helps to explain the exception noted above? ->Resolve the Paradox

Let's jot down the points:
Premise: RPL-> building material ->from waste plastic
Premise: RPL -no water absorption no insect damage
Conclusion: RPL replace traditional L BUT this RPL not recommended for interior residential projects.

RPL good then why it is not good for interior residential projects? Isn't? We need to find why?!?

A. Residential homes built entirely with recycled plastic lumber are virtually immune to damage from flooding.
INCORRECT. We need to find why RPL can't be used for INDOOR purposes. This sentence mentions about residential homes. Shell game.

B. Increased rates of thermal expansion and contraction of plastic lumber can cause doorways constructed of this material to warp and either fail to close or fail to seal tightly.
CORRECT the 'why' reason is mentioned here as to why plastic lumber is not recommended for indoors.

C. Currently 25 percent of the trash that is in landfills is plastic that could be used to produce recycled plastic lumber.
INCORRECT. How does this even matter? We already know waste plastics are used to make RPL from the first line of the paragraph.

D. Because of its resistance characteristics, recycled plastic lumber does not need to be treated with chemicals, allowing homeowners to live in an interior space with lower levels of chemicals.
INCORRECT. This sentence strengthens the argument and convinces to use RPL indoors.

E. Seldom painted, plastic lumber comes in different colors that can be chosen by the consumer.
INCORRECT. This sentences tries to attract the customers to buy some colorful lumber. Not required.

P.S: If you aren't sure of the options, you can always do POE and get option B as answer!

A, C, D, and E are incorrect because they do not explain the exception provided in argument by the author. They rather provide various justifications for the use of recycled lumber as an alternative building materials.
B on the other hand, explains the exception. This is because if it is true that thermal expansion and contraction can cause doorways to to warp and either fail to close or fail to seal tightly, then it gives enough explanation as to why it should not be used for interior residential projects, since doors are major parts of such projects.

Premise: Plastic bottles and other plastic waste is used to make recycled plastic lumber. It’s the quality o not getting rot, not absorbing water and resistant to insect damage that makes plastic lumber suitable or marine and outdoor applications.

Conclusion: So it is worth to replace traditional lumber in building projects except interior residential projects.

Correct answer must be something that supports the conclusion.

A. Residential homes built entirely with recycled plastic lumber are virtually immune to damage from flooding. – WRONG. It goes against the conclusion and supports the act that recycled plastic lumber is good for interior residential projects.

B. Increased rates of thermal expansion and contraction of plastic lumber can cause doorways constructed of this material to warp and either fail to close or fail to seal tightly. – CORRECT. The increased rate of thermal expansion and contraction would make plastic lumber unsuitable for the interior residential use. Safety concern of residents would be utmost priority in these projects.

C. Currently 25 percent of the trash that is in landfills is plastic that could be used to produce recycled plastic lumber. – WRONG. Irrelevant. Does not explain anything.

D. Because of its resistance characteristics, recycled plastic lumber does not need to be treated with chemicals, allowing homeowners to live in an interior space with lower levels of chemicals. – WRONG. Similar to A it also goes against the conclusion.

E. Seldom painted, plastic lumber comes in different colors that can be chosen by the consumer. – WRONG. Irrelevant. Does not explain anything, though assuming that it’s chemical-free it goes against the conclusion.

IMO Answer (B)

IMO it's B because it clearly mentions a disadvantage of using recycled plastic lumber.

Unlike traditional lumber, it won't rot or absorb water, and it is highly resistant to insect damage, so it is well-suited for marine and outdoor applications.

We have to basically find an option that explains why plastic lumber is not good for residential interiors.
Option A in turn kind of strengthen that plastic lumber is good that too for building the entire residential homes.
Option B correctly explains why plastic lumber isn't a good choice for residential interiors as it may contract/expand depending on heat or cool temperature.
Option C doesnt state anything useful information as effective explanation.
Optios D & E doesn't explain why plastic lumber te not preferred but rather goes on to support the opposite.

B. Nothing else is an obvious downside to interior application.

E. Seldom painted, plastic lumber comes in different colors that can be chosen by the consumer.


Official Explanation



Reading the question: We read the prompt, which is rich in fact and low in opinion. We have to explain an "exception." The exception, evidently, is "interior residential projects." The objectively best answer will have to do with the fact that this plastic lumber won't rot, won't absorb water, and is highly resistant to insect damage. We will look for explanations that are relevant directly or indirectly to this information.

Applying the filter: We don't see our expectation, but we can broaden and use a basic filter. The point is that we shouldn't use this houses. (A), (C), (D), and (E) all fail to hit that basic point, while (B) does. Basic relevance was sufficient, in this case.

The correct answer is (B).
