B. Analysts should consequently inspect the underlying distribution before concluding that nothing changed.
C. An average can remain constant even when the values beneath it change substantially.
D. The apparent stability may therefore result from offsetting movements rather than genuine absence of change.

Arrange the following sentences in the correct order.
A. Effective regulation therefore requires anticipating behavioural adaptation, not merely drafting formal restrictions.
B. The policy can then appear ineffective because people have adapted around it rather than complied in the intended way.
C. Firms may redesign contracts or transactions so that they technically satisfy the rule while preserving much of the original behaviour.
D. Regulations alter incentives, and regulated actors usually respond to those incentives.

Arrange the following sentences in the correct order.
A. These cases may then receive less attention precisely because the system becomes better at preventing them.
B. Maintaining safety therefore requires remembering that low accident rates may be evidence that prevention is working.
C. Successful safety systems often make serious accidents rare.
D. As accidents become uncommon, managers may begin questioning the need for expensive preventive measures.

Arrange the following sentences in the correct order.
A. Teams become skilled at performing narrow tasks repeatedly and at low cost.
B. Specialisation can make organisations highly efficient under stable conditions.
C. As the environment changes, however, the same specialised structure may become harder to adapt.
D. Resilience may therefore require preserving some flexibility even when specialisation appears more efficient.

Arrange the following sentences in the correct order.
A. Patients who choose an optional therapy may differ systematically from those who decline it.
B. Researchers must consequently account for selection effects when treatment is not randomly assigned.
C. A simple comparison may therefore confuse treatment effects with the reasons people chose treatment in the first place.
D. They may, for example, be wealthier, more motivated or healthier at the beginning.

Arrange the following sentences in the correct order.
A. A shared power source, software provider or communication network can create common vulnerability.
B. Instead, several apparently independent failures may have been triggered by the same hidden cause.
C. Investigations should therefore search for common dependencies before treating simultaneous failures as independent.
D. When multiple systems fail at the same time, observers may assume that several unrelated problems occurred coincidentally.

Arrange the following sentences in the correct order.
A. Long-term budgeting should consequently recognise avoided failures as a real benefit.
B. Preventive maintenance produces costs immediately, while many of its benefits take the form of failures that never occur.
C. That creates an incentive to postpone maintenance even when deterioration is gradually increasing future risk.
D. Managers under short-term budget pressure may therefore see maintenance mainly as an expense.

Arrange the following sentences in the correct order.
A. Security measures are intended to reduce unauthorised access.
B. Effective security design must therefore balance protection with usability.
C. Employees may begin sharing passwords or bypassing procedures if normal access becomes excessively inconvenient.
D. Yet very strict security can also make legitimate use so difficult that users seek unsafe workarounds.

Arrange the following sentences in the correct order.
A. A model estimated during years of stable inflation may perform poorly after a major monetary-policy shift.
B. Forecasting models should therefore be tested for structural change rather than assuming permanent relationships.
C. Relationships between economic variables can change when institutions, technology or policy regimes change.
D. This means that correlation calculated during one period may not remain stable in another.

Arrange the following sentences in the correct order.
A. Programme evaluation should therefore consider spillover effects where they are plausible.
B. Consequently, measuring only direct beneficiaries may substantially underestimate the programme’s total impact.
C. Vaccination, for example, can reduce infection risk for individuals who were never vaccinated.
D. Some interventions affect not only participants but also people connected to them.

Arrange the following sentences in the correct order.
A. The resulting estimate may therefore reflect both the intervention and the fact that only successful sites continued participating.
B. Evaluators should consequently track all original sites, including those that leave the programme.
C. A pilot programme begins in twenty locations, but several poorly performing locations withdraw before final evaluation.
D. The final report then summarises results only for the locations that remained.

Arrange the following sentences in the correct order.
A. Recommendations can therefore change the conditions on which those recommendations were based.
B. A navigation app recommends a previously quiet road because it is currently faster.
C. Once everyone begins using the route, however, congestion may erase the original advantage.
D. Many drivers receiving the same advice may switch to that road simultaneously.

Arrange the following sentences in the correct order.
A. A programme requires participants to submit regular online reports.
B. Reported outcomes may therefore overrepresent participants with better digital access.
C. Yet those who cannot comply may disappear from the dataset rather than show up as unsuccessful cases.
D. People with poor internet access are more likely to miss reports and eventually be classified as inactive.

Arrange the following sentences in the correct order.
A. Higher debt, however, can require households to reduce spending later in order to repay it.
B. This makes it possible for short-term gains to coexist with long-term losses.
C. Evaluating such a policy therefore requires examining effects across time rather than only the initial response.
D. A policy may stimulate current consumption by encouraging households to borrow more.

Arrange the following sentences in the correct order.
A. Reliable validation therefore requires genuinely unseen data or a properly separated test sample.
B. Analysts sometimes choose variables after examining the full dataset.
C. The model may then appear accurate because it is being tested on information it effectively already used.
D. If the same data are later used to test the model, the evaluation is no longer fully independent.

Arrange the following sentences in the correct order.
A. Competitive environments sometimes reward relative position rather than absolute performance.
B. Students may all spend increasingly more time on test preparation simply to avoid falling behind one another.
C. Such arms races illustrate how rational individual behaviour can generate socially inefficient outcomes.
D. In that situation, greater individual effort can leave everyone with roughly the same relative position but higher total costs.

Arrange the following sentences in the correct order.
A. The reported confidence interval may therefore be narrow even though uncertainty about the model itself is substantial.
B. Decision-makers should consequently distinguish uncertainty within a model from uncertainty about which model is appropriate.
C. Quantitative forecasts often express uncertainty conditional on a particular model and its assumptions.
D. This can produce misleading certainty when the model excludes plausible alternatives from the outset.

Arrange the following sentences in the correct order.
A. Pre-specification therefore helps distinguish genuine evidence from results produced by repeated searching.
B. But if the threshold is changed after researchers see the results, the probability of finding an apparently favourable result increases.
C. Researchers may otherwise try several definitions, thresholds or subgroups and report only the one producing the strongest result.
D. Statistical rules are most informative when they are specified before the data are analysed.

Arrange the following sentences in the correct order.
A. Institutions capable of identifying mistakes early can correct them before small problems become systemic failures.
B. Systems that hide mistakes in order to appear flawless may instead allow weaknesses to accumulate unnoticed.
C. No complex organisation can eliminate every error, uncertainty or unexpected event.
D. The goal of robust design is therefore not perfection but the ability to detect, contain, recover from and learn from failure.
