Which two methods can guests use to take a survey?

The correct choice indicates that guests can participate in a survey using a smartphone and online. This method reflects modern consumer behavior where many individuals prefer digital interactions due to convenience and accessibility. Using a smartphone allows guests to respond to surveys at their own convenience wherever they are, enhancing the likelihood of participation. Online surveys can also be designed to be user-friendly and quick, which tends to encourage feedback.

In contrast to the other methods, although they may still be viable, they typically involve more steps or may not appeal to the broader audience. For example, while respondents can use paper forms in person, this limits participation to those who are physically present at a location, potentially reducing the number of responses. Similarly, text message and phone call methods may not be as appealing or efficient as online submissions. Lastly, while a tablet in-store could be used for surveying, it is less common compared to smartphones and may still require physical presence, which isn't as conducive to maximizing response rates.
