Questions: Identify the grounds for the following enthymeme: Airport screeners should use racial profiling because doing so will increase the odds of stopping terrorists. Evidence showing that there is not a high correlation between race and terrorism. Evidence showing there is a high correlation between race and terrorism. Evidence showing that airport screeners are racist. Evidence showing that airport screeners need to be more stringent.

The answer is: Evidence showing there is a high correlation between race and terrorism.

Explanation for each option:

1. Evidence showing that there is not a high correlation between race and terrorism:

   • This option is incorrect because it contradicts the premise of the enthymeme. If there is no high correlation between race and terrorism, then using racial profiling would not logically increase the odds of stopping terrorists.

2. Evidence showing there is a high correlation between race and terrorism:

   • This is the correct answer. The enthymeme suggests that racial profiling will increase the odds of stopping terrorists. For this argument to hold, there must be evidence supporting a high correlation between race and terrorism. This evidence would justify the use of racial profiling as an effective measure.

3. Evidence showing that airport screeners are racist:

   • This option is incorrect because it does not directly support the argument that racial profiling will increase the odds of stopping terrorists. Instead, it introduces a different issue related to the biases of airport screeners, which is not the focus of the enthymeme.

4. Evidence showing that airport screeners need to be more stringent:

   • This option is also incorrect. While it suggests a need for more stringent measures, it does not specifically address the use of racial profiling or provide a direct link to the effectiveness of racial profiling in stopping terrorists.
