hard · LSAT Logical Reasoning

A municipal study found that neighborhoods that installed brighter LED streetlights last year reported 30 percent fewer nighttime burglaries than neighborhoods that retained their older sodium-vapor lamps. The city council concluded that brighter streetlighting deters burglars, and it has proposed converting every remaining neighborhood to LED lighting in order to reduce crime citywide.

Which one of the following, if true, most weakens the council's argument?

  1. The neighborhoods that received LED lighting were selected precisely because residents there had recently organized active citizen patrols, which are independently known to reduce burglary.
  2. LED streetlights consume substantially less electricity than the older sodium-vapor lamps did, lowering the city's overall annual energy expenditures all across its many separate districts.
  3. Brighter streetlighting, once it is installed, completely and permanently eliminates the very possibility of any nighttime crime whatever ever occurring within the illuminated areas.
  4. Daytime residential burglaries increased slightly across all of the city's neighborhoods alike during the very same one-year period that the council's lighting study happened to cover.
  5. Residents of the LED-equipped neighborhoods reported feeling considerably safer when walking outdoors after dark than they recalled ever feeling under the older sodium-vapor lamps.
