StrengthenDiff: Easy

Logic Breakdown

Passage Summary: Critics say digging up peat will ruin the water supply, but the author points to Ireland—where they've done it for a long time without issues—as proof that it's perfectly safe to do here.

Conclusion: It is safe to proceed with peat harvesting in this country.

Reasoning: Ireland has harvested peat for centuries without water contamination, which contradicts the claim that harvesting leads to contamination.

Analysis: The author is relying on an analogy between Ireland and 'this country.' To strengthen this argument, we need to ensure that the two locations are actually comparable. If the wetlands in Ireland are fundamentally different from the ones here, the Irish experience doesn't tell us much. Look for an answer that suggests the environmental conditions or the harvesting methods are similar enough that the success in Ireland can be expected to repeat here.

3.

Which one of the following, if true, most strengthens the argument?

Correct Answer
B
By establishing that Ireland’s peat-harvesting areas originally had virtually the same ecology as our undisturbed wetlands, it makes the Irish case a strong analogue. That similarity supports the inference that our water supply would likewise avoid contamination.
