Original passage: shared drying machines
An agricultural cooperative lends small drying machines to growers. Its original policy required each borrower to return a machine after exactly three days. This was easy to administer, but it sometimes left machines idle: a grower who finished in one day had little reason to return early, while a grower whose harvest arrived late might need a fourth day. The cooperative considered charging by the hour. That approach could encourage early returns, but it would require reliable meters and might penalize growers whose crops dried slowly through no fault of their own.
Instead, the cooperative adopted a reservation system with a refundable deposit. A grower identified an expected return time; returning by that time preserved the full deposit, while unexplained delays incurred a charge. A weather-related delay could receive an extension if the grower notified the next borrower early enough to rearrange collection. The policy was intended to reduce avoidable uncertainty for the next user, rather than to make every loan equally short. Its success depended on borrowers being able to estimate their needs reasonably and on the cooperative communicating changes promptly.
This arrangement illustrates a distinction between rewarding an outcome and rewarding coordination. Where completion times are partly outside a participant's control, incentives tied solely to speed may be both unfair and ineffective. An incentive tied to a credible commitment can better serve a shared schedule, provided that exceptions are verifiable and the next user's plans can genuinely be adjusted. The cooperative's experience does not establish that deposits are appropriate for every shared resource; a deposit too large for some growers to afford would create a different problem.

Extract a principle with its conditions
Application questions ask how a passage’s ideas bear on a new case. Before comparing scenarios, write the principle in an if–then form with all material conditions: when completion is partly outside participants’ control, a credible commitment may coordinate use better than a pure speed incentive, provided exceptions are verifiable and later plans are adjustable.
Do not compress that into “deposits are good” or “speed is bad.” The mechanism is predictable coordination, not the particular object being lent. The passage also includes feasibility constraints: reasonable estimates, prompt communication and affordable deposits.
ORIGINAL WORKED EXAMPLE
State the usable rule
Which principle best captures the author’s lesson? A: All loans should last three days. B: Deposits always eliminate delays. C: Credible commitments can improve coordination when exceptions are verifiable and schedules adjustable. D: Weather should never affect contracts. E: All users must pay equal charges.
The last paragraph generalizes from the lending arrangement to coordination.
C keeps the mechanism and conditions. A describes the abandoned policy; B removes uncertainty; D contradicts the exception; E invents a fairness rule.
Answer C
03 / UNDERSTAND & APPLY
Match relationships rather than nouns
A good analogy preserves roles: current user, shared resource, later user, uncertain completion, credible promise and advance communication. Two stories about farming can be poor analogies if their decision structures differ. A story about a laboratory instrument can be a strong analogy if the same scheduling problem exists.
An analogy is not a proof of identical results. Relevant differences may break the mechanism. Ask which feature made the original proposal work and whether that feature survives in the new situation.
ORIGINAL WORKED EXAMPLE
Compare two new settings
Which more closely matches the principle? A: A lab asks researchers to book realistic instrument slots and report verified experiment delays early enough to reschedule the next group. B: A shop charges every customer the same price for a notebook.
A includes sequential users, uncertain completion, advance notice and adjustable schedules.
B has a payment rule but no shared scheduling problem or credible-return mechanism.
Answer A; the relational structure matters more than whether money changes hands.
04 / UNDERSTAND & APPLY
Identify a condition that cannot be dropped
Some details decorate a scenario; others are necessary to the proposed mechanism. A drying machine’s color is irrelevant. Whether later borrowers can adjust their collection plans is central because advance notice is useful only if it enables action.
When a question asks which case is least suitable, look for a broken condition, not merely a different industry. Avoid adding a condition that the passage never requires, such as perfectly equal loan lengths.
ORIGINAL WORKED EXAMPLE
Find the broken condition
A hospital instrument must be available for the next procedure at an unchangeable time. Would an early-notice exception alone provide the same coordination benefit?
The new setting lacks the ability to adjust the next user’s schedule.
Notice may still be informative, but it cannot by itself produce the specific benefit described in the passage.
Answer No; the adjustable-schedule condition fails. This does not establish that every form of advance notice is useless.
05 / UNDERSTAND & APPLY
Hypothetical information changes a conclusion through a link
Treat hypothetical facts as true for the question. Locate the link they affect: affordability, estimate accuracy, verification or scheduling response. New information can strengthen an application, weaken it or be irrelevant. It need not refute the whole passage.
If new facts show a deposit excludes low-income growers, they undermine the accessibility of that implementation. They do not show that coordination incentives can never work. Keep the target conclusion as narrow as the evidence warrants.
ORIGINAL WORKED EXAMPLE
Evaluate a new fact
Suppose half the growers cannot afford the required deposit. What changes?
The passage explicitly flags unaffordable deposits as a different problem.
Exclusion becomes a serious cost of this implementation even if it improves timing among participants.
A lower deposit, guarantee or different commitment mechanism might address the cost, but the passage does not establish which would work.
Answer The evidence weakens the case for this deposit level, not the general importance of coordination.
06 / UNDERSTAND & APPLY
Compare cases using the same criteria
A disciplined comparison holds the goal constant and evaluates each case against the same conditions. Do not praise one policy for fairness and reject another solely for administrative effort without recognizing that you changed the criterion.
A stronger application can acknowledge a trade-off. The deposit plan may reduce uncertainty but require staff time to verify exceptions. A reading question asks what follows from the passage’s position, not what policy you personally prefer.
ORIGINAL WORKED EXAMPLE
Choose the supported modification
The cooperative can verify delays but often fails to notify the next borrower. Which change most directly supports its stated mechanism? A: Repaint machines. B: Raise every deposit. C: Introduce reliable same-day delay notices. D: Ban every extension. E: Count total growers annually.
The mechanism depends on prompt communication so plans can be adjusted.
C repairs the specified failure. A and E do not address timing; B does not transmit information; D removes a potentially useful exception rather than fixing communication.
Answer C
07 / UNDERSTAND & APPLY
Keep the passage’s scope during transfer
“Can better serve” is a conditional possibility, not a guarantee. The argument is about shared schedules under uncertain completion, not a universal theory of motivation. A valid application must preserve that limited force.
Before selecting an answer, complete this sentence: “This new case fits because ___, provided ___.” If you cannot fill both blanks from the text and the scenario, you may be matching superficial details.

Practice: apply the full principle
Use the drying-machine passage. Select one option where choices are supplied.
ORIGINAL PRACTICE · 1
1. A shared rehearsal room has unpredictable setup time, verifiable equipment failures and flexible later bookings. Which policy best reflects the passage? A: Penalize every overrun identically. B: Reward realistic finish commitments and prompt verified updates. C: Eliminate booking records. D: Require all rehearsals to be equally short. E: Charge according to room color.
Reveal answer & reasoning
B
B preserves credible commitments and adjustable exceptions. A ignores uncontrollable delays; C removes coordination; D substitutes equal duration for the goal; E is irrelevant.
ORIGINAL PRACTICE · 2
2. Would identical three-day limits for all borrowed objects follow from the principle?
Reveal answer & reasoning
No.
The passage criticizes the original fixed limit and distinguishes coordination from equal duration. A copied surface number does not transfer the principle.
ORIGINAL PRACTICE · 3
3. What does reliable delay verification contribute?
Reveal answer & reasoning
It makes exceptions credible and reduces the opportunity to evade a commitment through unsupported excuses.
The final paragraph requires verifiable exceptions. It does not claim verification prevents weather or eliminates every late return.
ORIGINAL PRACTICE · 4
4. A borrower always knows the exact finish time and can freely return a machine early. Does the passage prove a deposit is necessary?
Reveal answer & reasoning
No.
The passage concerns a conditional coordination problem and says deposits are not appropriate for every resource. Exact estimates and easy early returns may change the need for that mechanism.
ORIGINAL PRACTICE · 5
5. Which new fact most directly weakens the notice-based mechanism? A: Machines are painted blue. B: The next borrower can reschedule easily. C: Notices arrive only after the next borrower has traveled to collect the machine. D: Weather delays are documented. E: Borrowers can make reasonable estimates.
Reveal answer & reasoning
C
Late notice cannot support advance adjustment. B, D and E support stated conditions; A is irrelevant.
ORIGINAL PRACTICE · 6
6. Why is hourly charging not treated as an unqualified solution?
Reveal answer & reasoning
It needs reliable meters and can penalize uncontrollably slow drying.
Both concerns appear in the first paragraph. The text does not say hourly charging can never encourage early returns.
09 / UNDERSTAND & APPLY
Practice: distinguish principle from preference
A design studio lends cameras. Repair-related delays are documented, and later borrowers can exchange time slots. One manager favors a notice-based reservation system; another favors a deposit so high that fewer than half of members can participate.
ORIGINAL PRACTICE · 1
7. Which part of the passage supports the first manager, and which limits the second?
Reveal answer & reasoning
Verifiable exceptions and adjustable schedules support notice-based commitments; the affordability warning limits a very high deposit.
The same passage can support the coordination mechanism while criticizing an inaccessible implementation. These positions are consistent.
ORIGINAL PRACTICE · 2
8. Would the passage justify the claim that the studio should ignore all financial costs?
Reveal answer & reasoning
No.
The passage warns about affordability and administrative requirements. Its principle is conditional and does not erase costs or provide a complete policy ranking.
