Several different means of smuggling, such as cross-border tunnels, are used to bring narcotics, individuals, and contraband into the United States. Cross-border tunnels can be found all along the land border of the United States. They vary significantly in size and complexity of construction, although most are crudely constructed. Further, most crossborder tunnels are used for smuggling narcotics, although illegal aliens and other contraband have also been smuggled using tunnels.
  1. Most cross-border tunnels are not skillfully constructed
  2. All cross-border tunnels are used for narcotics smuggling
  3. At least some cross-border tunnels are not free from narcotics smuggling
  4. At least some of the means used for narcotics smuggling are cross-border tunnels
  5. At least some means used for narcotics smuggling involve crudely constructed tunnels
Explanation
Answer: B - This is an example of a test question with a negative lead statement. It asks for the conclusion that is NOT supported by the paragraph. That means that four of the statements are valid conclusions based on the paragraph while one is not. In this case, Response B is invalid. The paragraph says that “most” cross border tunnels are used for smuggling narcotics, but Response B says that “all” cross border tunnels are used for smuggling narcotics.

Responses C and D are based on the information that most cross border tunnels are crudely constructed. Response C is based on the information that most cross border tunnels are used to smuggle narcotics. Finally, Response E combines all information about the tunnels being crudely constructed and used for smuggling narcotics.
