Formulating a question from a list
Part of working with data is becoming proficient and familiar with inspecting and understanding data frames, lists, and vectors. However, it's important to be able to communicate your findings with reports and plots in a human-readable way across any organization. In the video exercise, you saw how to create sentences from lists with the glue_collapse() function.
In this exercise, you will create a small questionnaire with glue_collapse() that could later be fed to the base R command menu().
