Which of the following is an example of passive enumeration?

To determine which of the following options is an example of passive enumeration, we first need to understand what passive enumeration means. Passive enumeration refers to the process of gathering information or data without actively engaging or interacting with the target.

Now, let's examine the given options and identify the one that fits this definition:

Option 1: Conducting a survey and asking individuals about their preferences - This option involves actively engaging with individuals and asking for their input. Therefore, it does not represent passive enumeration.

Option 2: Observing and recording the number of cars passing by a specific location - This option involves passively observing and recording data without actively interacting with the cars. It aligns with the definition of passive enumeration.

Option 3: Interviewing customers to gather feedback on a product - Similar to option 1, this option involves actively engaging with customers and seeking their feedback. It does not represent passive enumeration.

Based on the analysis, option 2, which involves observing and recording the number of cars passing by a specific location, is an example of passive enumeration.
