Marcie: A better use of the money would be for a public works project that would create jobs.
Speaker 1 Summary
Jessica believes that the budget surplus should be used only to increase government payments to unemployed people.
Speaker 2 Summary
Marcie argues that a better use of the surplus would be for a public works project that would create jobs
Objective
Disagreement: Jessica and Marcie disagree about how the surplus can be best spent
A
Using the budget surplus to increase government payments to those who are unemployed is putting the money to good use.
Jessica certainly agrees with this statement, but Marcie does not provide any opinion. While Marcie believes the money could be better spent, that does not mean she dislikes increasing government payments to unemployed people.
B
The public deserves to have jobs created when there are many people who are unemployed.
Jessica does not give an opinion on this. It is unclear whether Marcia would agree with this because there is no indication that “many people” are currently unemployed.
C
When there is a choice between increasing payments to the unemployed and funding a public works project, the latter should usually be chosen.
Both speakers do not give an opinion on this. The stimulus is purely related to how a budget surplus should be spent; this answer choice is far too broad for the speakers to give an opinion.
D
Creating jobs through a public works project will ultimately benefit the public.
Marcie certainly agrees with this, but Jessica does not mention any positive/negative sentiments about a public works project.
E
There is a better way to use the budget surplus than increasing government payments to those who are unemployed.
Jessica disagrees with this statement because she believes increasing government payments is best. Marcie agrees with this statement because she wants to fund a public works project with the surplus.
All potatoes naturally contain solanine, which is poisonous in large quantities. Domesticated potatoes contain only very small amounts of solanine, but many wild potatoes contain poisonous levels of solanine. Since most of the solanine in potatoes is concentrated in the skin, however, peeling wild potatoes makes them at least as safe to eat as unpeeled domesticated potatoes of the same size.
Summary
For a given size of potato, a peeled wild potato is at least as safe as an unpeeled domesticated potato. Why? Because in any potato, most of the solanine (which is poisonous) is contained in the skin.
Missing Connection
The conclusion draws a comparison between the safety of peeled wild potatoes and unpeeled domesticated potatoes. But the premises only allow us to compare between peeled and unpeeled potatoes of the same kind. (A peeled potato should have less poison than an unpeeled potato of the same kind.)
How to get from premises to conclusion? We need to know how solanine content actually compares between peeled wild potatoes and unpeeled domesticated ones. If we knew that the solanine content that’s left over in a peeled wild potato is no higher than the entire solanine content of a same-size unpeeled domesticated potato, we could reach the conclusion.
A
The proportion of a potato’s solanine that is contained in its skin is larger in wild potatoes than in domesticated potatoes.
This compares proportions, but we need to compare absolute quantities. How much solanine is actually left over in a peeled wild potato, and how does that compare to an unpeeled domesticated one? (A) doesn’t answer either of those questions.
B
The amount of solanine concentrated in the skin of a wild potato is large enough by itself to be poisonous.
This only tells us about the poison content of wild potato skin, which is irrelevant. We need to know the amount of solanine left over in a wild potato without skin, and how that compares to the amount in a domesticated potato with skin. (B) ignores both sides of the comparison.
C
There is no more solanine in a peeled wild potato than in an unpeeled domesticated potato of the same size.
This compares the solanine content of a peeled wild potato and a same-size unpeeled domesticated one, and confirms that the wild potato comes in at the same amount of solanine or less. So we can conclude that peeled wild potatoes are indeed at least as safe.
D
There are no poisonous substances in domesticated potatoes other than solanine.
This ignores wild potatoes, so it can’t help us reach the comparison in the conclusion. The fact that solanine is the only poison in domesticated potatoes doesn’t tell us how much poison is in a peeled wild potato, or how that compares to the poison in a domesticated potato.
E
Wild potatoes are generally much smaller than domesticated potatoes.
Irrelevant. The conclusion is only about wild and domesticated potatoes of the same size.
