Leachate is a solutions, frequently highly contaminated, that develops when water permeates a landfill site, If and only if the landfill's capacity to hold liquids is exceeded does the leachates escape into the environment, generally in unpredictable quantities, A method must be found for disposing of leachate. Most landfill leachate is send directly to sewage treatment plants, but not all sewage plants are capable of handling the highly contaminated water.

Which one of the following can be inferred from the passage?

(A) The ability to predict the volume of escaping landfill leachate would help solve the disposal problem.

(B)If any water permeates a landfill, leachate will escape into the environment.

(C) No sewage treatment plants are capable of handling leachate.

(D) Some landfill leachate is send to sewage treatment plants that are incapable of handling it.

(E) If leachate does not escape from a landfill into the environment, then the landfill's capacity to hold liquids has not been exceeded.

I was stuck between D and E but I think E is stronger.

(D) Some landfill leachate is send to sewage treatment plants that are incapable of handling it. even though there are plants that are incapable of handling leachate (as it was mentioned in the last sentence), it would be presumptuous of us to assume that the leachate are actually sent to those plants. Maybe leachates are only sent to sewage plants that can handle it. We cannot say.

(E) If leachate does not escape from a landfill into the environment, then the landfill's capacity to hold liquids has not been exceeded. as stated in the argument - "if and only if".

Good analysis. I was stuck between D and E forever before figuring this out.

I get E for this. the "if and only if" is pretty damning, so you need something equally strong.

Agree with beckee529...E it is.

agree with E

D is mild and has the possibility of sewage plans not receiving leachate at all

IF AND ONLY IFF

If you negate one, you negate the other. It's written right there.

I agree with E...but I want to play devil's advocate here for a second.

Quote:
(E) If leachate does not escape from a landfill into the environment, then the landfill's capacity to hold liquids has not been exceeded.

Can we assume that it is impossible for the landfill's capacty to hold liquids to be exceeded without leachate being produced? The passage never says anything concrete to prove this.

It's implied, but can we really know for sure? Leachate develops when water permeates a landfill site....but what if a landfill site's capacity to hold liquids could be exceeded without water permeating it? maybe someone poured a whole ton of milk into the landfill. Then the landfill could exceed capacity without leachate being leaked...because it was never formed.

but D is an even weaker answer, so I'd choose E.

Can you deny D or E?

Before the thread gets lost, can you please provide us with the OA? Thanks!

I dont have an OA/OE for this, but thought Id put it up for discussion amongst our great community here.

E.

(A) The ability to predict the volume of escaping landfill leachate would help solve the disposal problem.

(B) If any water permeates a landfill, leachate will escape into the environment.
NO. Leachate will only escapes if it exceeds the holding capacity of the landfil.

(C) No sewage treatment plants are capable of handling leachate.
NO. Seems extreme statement ( but not all sewage plants are capable of handling the highly contaminated water.)

(D) Some landfill leachate is send to sewage treatment plants that are incapable of handling it.

(E) If leachate does not escape from a landfill into the environment, then the landfill’s capacity to hold liquids has not been exceeded.
YES, (If and only if the landfill’s capacity to hold liquids is exceeded does the leachate escape)

D

Leachate is a solution, frequently highly contaminated, that develops when water permeates a landfill site. If and only if the landfill’s capacity to hold liquids is exceeded does the leachate escape into the environment, generally in unpredictable quantities. A method must be found for disposing of leachate. Most landfill leachate is send directly to sewage treatment plants, but not all sewage plants are capable of handling the highly contaminated water.

The main idea: There is a problem: we cannot fully protect environment from highly contaminated leachate.

Which one of the following can be inferred from the passage?

(A) The ability to predict the volume of escaping landfill leachate would help solve the disposal problem. - extra information.
(B) If any water permeates a landfill, leachate will escape into the environment. - is not true.
(C) No sewage treatment plants are capable of handling leachate. - is not true.
(D) Some landfill leachate is send to sewage treatment plants that are incapable of handling it. - it is the problem discussed in the passage."Some landfill leachate" refers to "a solution frequently highly contaminated"
(E) If leachate does not escape from a landfill into the environment, then the landfill’s capacity to hold liquids has not been exceeded. - too particular information. Nothing about inability to treat dangerous leachate. we have inferred question rather than "must true" one.

I am with you Walker. I think it's D also.

shouldn't worry about predicting how much water escapes the landfill
(B) If any water permeates a landfill, leachate will escape into the environment.
irrelevant, it's testing the word "to permeate"
(C) No sewage treatment plants are capable of handling leachate. irrelevant
(D) Some landfill leachate is send to sewage treatment plants that are incapable of handling it.
this is exactly what the last sentence of the passage is saying
(E) If leachate does not escape from a landfill into the environment, then the landfill’s capacity to hold liquids has not been exceeded. this is saying that is the toxic substance does not escape the environment, then the environment that hold the water is not full yet. it means that it's waiting for the water to overflow.

Could anybody clarify why D is incorrect?
