Which of the following values cannot be "piped in" using the Piped Text Feature?

The reason survey expiration cannot be piped in using the Piped Text feature is that it refers to a specific system-level characteristic rather than an individual response or variable associated with the survey participant. Piped Text is designed to dynamically insert values based on the data collected, such as embedded data, response choices, or contact information that pertains to respondents.

In contrast, embedded data, answer choices, and contact information represent values that are directly related to the individual taking the survey or the specific data collected during the survey process. They can be personalized and used to enhance the survey experience, making them suitable candidates for piped text. Survey expiration, however, does not align with these characteristics, as it is a static parameter related to the survey's lifecycle rather than the content or context of the responses.
