A SARA analysis of late-night assaults finds that fights usually begin over line-cutting at an unmanaged taxi queue when several venues close together. Assaults inside the venues are uncommon. Police, venue managers, and transport operators can alter departure arrangements. Which response best addresses the mechanism identified?
Correct answer: D - Stagger venue departures and introduce supervision of the shared taxi queue.
Two tablet models have similar prices, sizes, stock availability, and display security. Retailers nevertheless report repeated thefts of one model. Interviews with arrested sellers indicate that this model can be resold quickly to numerous buyers, while the other is difficult to sell. Within CRAVED, which characteristic most directly captures that difference?
Correct answer: B - Disposable: ease of finding buyers for the stolen item.
An agency's Incidents table has one row per incident and a unique IncidentID. Its Arrests table has one row per arrest, so several rows can share an IncidentID; some incidents have no arrest. After a left join from Incidents to Arrests, the analyst needs the number of incidents in each district, including incidents without arrests. Which aggregation preserves that counting unit?
Correct answer: A - Keep the left join and count distinct Incidents.IncidentID values by district.
An after-action report credits directed patrol with reducing assaults at six street segments. The segments were selected after an unusually high month, and the city has marked seasonal swings in violence. Random assignment was not used. To test whether patrol contributed more than seasonal change and regression to the mean, the strongest addition would be:
Correct answer: A - Untreated segments meeting the same peak-month selection rule, with assault counts for both groups across several periods before and after deployment.
A 90-day residential-burglary comparison uses these figures: North, 24 residential and 12 commercial burglaries, 6,000 occupied dwellings; South, 18 residential and 24 commercial burglaries, 3,000 occupied dwellings. For residential burglaries per 1,000 occupied dwellings, the correct comparison is:
Correct answer: B - North: 4; South: 6. South has the higher rate.
An Excel worksheet has one row per burglary: occurrence date-times in A2:A501 and districts in B2:B501. All date-times are numeric Excel values. F1 is May 1, 2026 at 00:00; G1 is June 1, 2026 at 00:00. North records include May 1 at 00:00, May 31 at 18:30, and June 1 at 00:00. Using English function names and comma-separated arguments, which formula counts all North burglaries in May and none in June?
Correct answer: D - =COUNTIFS(B2:B501,"North",A2:A501,">="&F1,A2:A501,"<"&G1)
An informant with a usually accurate reporting history relays a claim that a warehouse stores stolen goods. The informant heard this from an acquaintance and has no personal knowledge of the warehouse's contents. No independent evidence supports the claim yet. The assessment should record:
Correct answer: B - Usually reliable source; secondhand information lacking independent corroboration.
'Why did East District get darker when its burglary rate fell from 12 to 10 per 1,000 households?' A reviewer asks this about two annual choropleth maps. District boundaries are unchanged, but natural breaks were calculated independently for each year. The maps are meant to compare absolute rates. Which revision ensures that the same color denotes the same rate range in both maps?
Correct answer: A - Apply common numerical class boundaries and the same color-to-class assignments to both annual maps.
Four shop robberies have been provisionally linked by an unusual demand made to employees. A proposed suspect has an independently verified alibi covering the entire third robbery, whose occurrence time is established by video. The alibi does not cover the other robberies, and investigators have not established whether the offenses involved one person or several. What does this evidence require the analyst to revise?
Correct answer: C - Reject the claim that this suspect was the on-scene robber in all four incidents.
In a U.S. trafficking investigation, verified records show that an adult knowingly arranged commercial sex involving a 17-year-old and received part of the proceeds. The young person reports no force, fraud, or coercion, and all activity occurred within one state. Which conclusion correctly applies the federal minor-sex-trafficking distinction?
Correct answer: C - Sex trafficking involving a minor does not require proof of force, fraud, or coercion.
