LSAT Logical Reasoning › Apply the Principle
A landlord association states this principle for returning security deposits: A landlord must return a tenant’s deposit in full unless the landlord provides, within 14 days of move-out, an itemized list of deductions for unpaid rent or documented damage beyond normal wear. If the landlord does not provide that list within 14 days, no deductions may be taken. The association uses this principle to resolve deposit disputes.
Which one of the following most closely conforms to the principle stated above?
A landlord keeps part of the deposit for normal carpet wear and sends an itemized list within 14 days.
A landlord returns the deposit in full even though unpaid rent remains, because the tenant was otherwise respectful.
A landlord sends an itemized list of deductions for documented damage 10 days after move-out and returns the remainder of the deposit.
A landlord returns only part of the deposit for documented damage but sends the itemized list 20 days after move-out.
A landlord keeps part of the deposit for unpaid rent but does not send any itemized list, claiming the tenant already knows the reason.
Explanation
The principle requires landlords to provide an itemized deduction list within 14 days to justify keeping any deposit money; failure to provide this list within the timeframe means no deductions are permitted. This creates a procedural protection for tenants requiring timely documentation. Choice A correctly follows this principle: the landlord provides an itemized list of documented damage within 10 days (meeting the timing requirement) and returns the remainder, which is exactly what the principle requires. Choice B might seem reasonable since it involves documented damage, but providing the list 20 days after move-out violates the 14-day requirement, meaning no deductions should be allowed. When applying tenant protection principles, timing requirements are just as important as substantive justifications.
A principle in ethical leadership is that leaders should model the behavior they expect from others. This involves demonstrating integrity and responsibility in actions and decisions, setting a standard for others to follow. The principle above would most strongly support which one of the following?
A manager who expects punctuality ensures they are always on time.
A CEO who delegates all ethical decision‑making to a committee.
A supervisor who encourages teamwork but often works independently.
A director who promotes sustainability yet frequently flies on private jets.
A leader who demands honesty but occasionally withholds information.
Explanation
This ethical leadership principle requires leaders to model the behavior they expect from others by demonstrating integrity and responsibility in their own actions and decisions. Applying this principle correctly means identifying situations where leaders practice what they preach rather than creating double standards. Choice A perfectly exemplifies the principle: a manager who expects punctuality consistently demonstrates that same behavior, creating alignment between expectations and personal conduct. Choice B appears to involve leadership but contains a critical flaw—the leader 'demands honesty but occasionally withholds information,' creating exactly the kind of inconsistency the principle prohibits. For ethical leadership questions, look beyond whether the leader seems well-intentioned and verify they actually embody the standards they set for others—authentic modeling requires consistent alignment between personal behavior and stated expectations.
A library’s lending rule states this principle: A patron may renew a borrowed item only if (1) no one else has placed a hold on that item and (2) the patron has no overdue fines. If either condition is not satisfied, the renewal must be denied. The library applies this rule to all items, including books, DVDs, and tools.
Which one of the following most closely conforms to the principle stated above?
A patron is allowed to renew an item because the patron has no overdue fines, so holds are irrelevant.
A patron is denied renewal because another patron has placed a hold on the item, even though the patron has no overdue fines.
A patron with overdue fines is allowed to renew an item because no one has placed a hold on it.
A patron with no overdue fines is allowed to renew an item even though another patron has placed a hold on it.
A patron is denied renewal because the item is popular, even though no one has placed a hold and the patron has no overdue fines.
Explanation
The library's renewal principle allows a patron to renew an item only if no hold is placed on it and the patron has no overdue fines; denial is required if either condition fails, applied uniformly to all items. Correct conformance means denying renewal when any condition is unmet, without exceptions for popularity or other factors. Choice D adheres by denying renewal due to a hold, even though fines are absent, respecting the principle's requirement to check both elements. Choice B tempts by allowing renewal despite fines because no hold exists, misapplying the logic by treating conditions as optional rather than mandatory. Focus on matching the principle's exact structure and scope to avoid errors, as partial compliance doesn't suffice for approval.
A city’s ethics code states the following principle for awarding public contracts: A contract should be awarded to the lowest-priced bidder among those who (1) meet all safety requirements and (2) have no unresolved violations from the past two years. If no bidder satisfies both conditions, the contract should be postponed rather than awarded. The city is now deciding whether to award a contract for repairing a bridge, and several companies have submitted bids.
Which one of the following situations is most consistent with the principle stated above?
The city awards the contract to the lowest-priced bidder because it has no unresolved violations, even though it fails one safety requirement.
The city awards the contract to the second-lowest-priced bidder because the lowest-priced bidder is headquartered outside the city.
The city postpones awarding the contract because none of the bidders both meet all safety requirements and have no unresolved violations from the past two years.
The city awards the contract to the lowest-priced bidder that meets all safety requirements, even though it has an unresolved violation from last year.
The city awards the contract to the bidder with the best reputation for finishing early, even though another bidder is cheaper and also meets the conditions.
Explanation
The principle here requires awarding a public contract to the lowest-priced bidder only if they meet two conditions: satisfying all safety requirements and having no unresolved violations from the past two years; if no bidder meets both, the contract must be postponed. To apply this correctly, we look for a scenario where the city either selects the qualifying lowest bidder or postpones when none qualify, without introducing extraneous factors. Choice B exemplifies this by postponing the award because no bidder satisfies both conditions, directly adhering to the principle's logic of withholding the contract rather than compromising on the requirements. In contrast, a tempting wrong answer like D violates the principle by awarding to the lowest bidder despite failing a safety requirement, ignoring the mandatory condition. Remember, applying such principles demands matching both the scope—here, the specific conditions—and the structure, ensuring no exceptions are made even if it seems practical.
A neighborhood association adopts this principle for approving new exterior paint colors: A proposed color should be approved if it (1) is not fluorescent and (2) matches at least one color already used on a house within two blocks. If either condition is not met, the proposal should be rejected to preserve neighborhood consistency. The association is now evaluating several homeowners’ requests.
The principle above would most strongly support which one of the following?
A homeowner proposes a nonfluorescent color that matches a house three blocks away; the association approves it.
A homeowner proposes a fluorescent color that matches a nearby house; the association approves it.
A homeowner proposes a nonfluorescent color that matches a house within two blocks; the association rejects it because the board prefers neutral colors.
A homeowner proposes a color that does not match any nearby house; the association approves it because it is tasteful.
A homeowner proposes a nonfluorescent color that matches a house within two blocks; the association approves it.
Explanation
The neighborhood association's principle approves a new paint color if it's nonfluorescent and matches a house within two blocks; reject if either is missing to maintain consistency. Application requires approving only when both conditions are satisfied, without injecting preferences like tastefulness. Choice C supports the principle by approving a nonfluorescent color matching a nearby house, fulfilling both criteria logically. Choice B wrongly approves a fluorescent color that matches nearby, violating the nonfluorescent condition despite partial alignment. This highlights the need to verify every condition within the principle's scope and structure, ensuring decisions aren't swayed by subjective appeal.
A park’s enforcement policy states this principle: A visitor should receive a warning, rather than a fine, for a first offense only if (1) the visitor immediately stops the prohibited activity when informed and (2) the activity caused no damage to park property. If either condition is not met, the visitor should be fined. Rangers apply this policy to keep enforcement predictable.
The principle above would most strongly support which one of the following?
A visitor is fined for a first offense because the park is crowded, even though the visitor stopped immediately and caused no damage.
A visitor is warned because it is a first offense, so whether there was damage is irrelevant.
A first-time visitor caused no damage but refuses to stop; the ranger issues a warning.
A first-time visitor stops immediately but has already damaged a fence; the ranger issues a warning.
A first-time visitor stops immediately and caused no damage; the ranger issues a warning.
Explanation
The park's policy issues a warning for a first offense only if the visitor stops immediately and causes no damage; fine otherwise to ensure predictable enforcement. Application supports warning solely when both conditions are met, without considering factors like park crowding. Choice B strongly aligns by warning a first-timer who stops immediately with no damage, satisfying the principle's requirements. Choice C incorrectly warns despite refusal to stop, ignoring the immediate-stop condition in the principle's logic. Always cross-check conditions against the principle's structure, as this avoids leniency that could erode consistent rule application.
A city’s ethics code states the following principle for awarding contracts: A contract should be awarded to the lowest-priced bidder among those who meet all mandatory qualifications and submit a complete bid by the deadline. However, if the lowest-priced qualified bid contains a material error that cannot be corrected without changing the bid’s price or scope, that bid must be rejected and the contract awarded to the next-lowest qualified bid. Which one of the following situations is most consistent with the principle stated above?
Bidder A is lowest-priced and qualified, but the city prefers Bidder B’s past performance and awards the contract to Bidder B despite A’s complete, timely bid.
Bidder A is lowest-priced and qualified, but after the deadline it offers an additional discount; the city accepts the late discount and awards to A.
Bidder A is lowest-priced and qualified, and its bid contains a minor typo that does not affect price or scope; the city rejects A and awards to the next-lowest bidder.
Bidder A is lowest-priced, qualified, and timely, but its bid contains a pricing spreadsheet error that would require changing the total price; the city rejects A and awards to Bidder B, the next-lowest qualified bidder.
Bidder A is lowest-priced and qualified, but its bid omits a required safety certification; the city awards the contract to Bidder B, the next-lowest qualified bidder.
Explanation
The principle establishes a clear hierarchy: award to the lowest-priced qualified bidder who submits a complete, timely bid, BUT reject any bid with a material error that would change price or scope. Let's parse the key conditions: (1) lowest price among qualified bidders, (2) complete bid by deadline, and (3) no material errors affecting price/scope. Answer C perfectly applies this principle—Bidder A meets the first two conditions but violates the third because a pricing spreadsheet error would require changing the total price, making this a material error that triggers rejection. Answer B tempts us because it seems unfair to ignore past performance, but the principle doesn't allow subjective preferences to override the lowest-price rule when all conditions are met. When applying principles, check every condition systematically—a single violation of a mandatory requirement overrides all other considerations.
A university’s grade-appeal policy states this principle: An instructor must change a student’s course grade only if the student shows, with documentation, that either (1) the instructor made a calculation error in totaling points, or (2) the instructor applied a grading rule inconsistently compared with other students in the same course. Disagreement with the instructor’s academic judgment is not sufficient. Which one of the following most closely conforms to the principle stated above?
A student claims the instructor misread an essay and should have given more points; the instructor changes the grade without checking any records.
A student submits a note from a tutor stating the student understands the material; the instructor raises the grade.
A student argues the exam questions were unfair and asks for a higher grade; the instructor refuses to change the grade.
A student discovers the instructor added the points correctly but forgot to curve the class; the instructor changes the grade because the student requests it.
A student provides the rubric and graded papers showing late penalties were waived for several classmates but applied to the student; the instructor adjusts the grade accordingly.
Explanation
This principle requires documentation showing either a calculation error OR inconsistent application of grading rules—mere disagreement with academic judgment isn't enough. The principle operates as a strict conditional: change the grade if and only if documented evidence proves one of the two specified errors. Answer B correctly applies this principle: the student provides documentation (rubric and graded papers) proving the instructor applied late penalties inconsistently across students, satisfying the second condition for a grade change. Answer A might seem reasonable since unfair questions could warrant review, but this falls under "academic judgment" which the principle explicitly excludes as grounds for change. Remember that applying a principle means following its exact conditions, not expanding it to cover situations that seem similar but fall outside its defined scope.
A museum’s acquisition guideline states this principle: The museum should accept a donated artwork only if it can verify legal ownership and provenance to a reasonable standard and if accepting the donation will not obligate the museum to restrictions that prevent normal display or conservation. If either provenance cannot be reasonably verified or restrictive conditions would prevent normal stewardship, the donation should be declined. Which one of the following situations is most consistent with the principle stated above?
A donor offers a photograph with verified provenance, but the museum declines because it already owns similar photographs.
A donor offers a painting with unverifiable provenance; the museum accepts it only if the donor signs a display agreement.
A donor offers a painting with well-documented provenance but requires it never be displayed publicly; the museum accepts the donation.
A donor offers a drawing with verified ownership records and no display or conservation restrictions; the museum accepts the donation.
A donor offers a sculpture with incomplete provenance, but the museum accepts it because it would attract visitors.
Explanation
The museum's principle creates a two-part test: (1) verify legal ownership and provenance to a reasonable standard, AND (2) ensure no restrictions prevent normal display or conservation. Both conditions must be satisfied to accept a donation; failing either one requires declining. Answer C correctly applies this principle—the drawing has verified ownership records (satisfying condition 1) and no display or conservation restrictions (satisfying condition 2), so the museum properly accepts it. Answer A might seem like it follows the principle since provenance is documented, but requiring the artwork never be displayed publicly violates the second condition about restrictions preventing normal display. When principles use "and" between conditions, treat them as a checklist where every box must be checked—one satisfied condition cannot compensate for another that's violated.
According to the principle of risk management, one should identify potential risks and take proactive steps to mitigate them before they materialize. This involves assessing vulnerabilities and implementing strategies to minimize negative impacts. Which one of the following most closely conforms to the principle stated above?
A business waits until a major incident occurs before addressing its security weaknesses.
A manager decides to ignore potential risks because they seem unlikely.
An organization focuses solely on maximizing profits without considering potential risks.
A company conducts a thorough risk assessment and updates its disaster recovery plan.
A project leader believes risks should be addressed only when they become problematic.
Explanation
This risk management principle requires identifying potential risks and taking proactive steps to mitigate them before they materialize through vulnerability assessment and strategic implementation. Correctly applying this principle means finding actions that demonstrate forward-thinking preparation rather than reactive responses to problems. Choice A exemplifies proper application by conducting thorough risk assessment and updating disaster recovery plans, showing both identification and proactive mitigation of potential problems. Choice B completely contradicts the principle by waiting 'until a major incident occurs before addressing security weaknesses,' representing reactive rather than proactive management. The key to risk management questions is distinguishing between preparation and reaction—the principle demands anticipating and preventing problems, not just responding effectively once they occur.
