What are two elements in the Call Studio application to collect Caller Response?

According to the Cisco Unified Call Studio User Guide, Release 12.5 (1) and 12.5 (2), there are two types of elements in the Call Studio application that can collect caller response: Menu Element and Digits Element1. The Menu Element captures a single digit from the caller and maps it to a menu option2. The Digits Element captures a string of numerical digits from the caller and stores it in an element data variable3. The other options are not correct, because they are either not elements in the Call Studio application or do not collect caller response as described. There is no Digital tone element or Digits element that captures a single digit in the Call Studio application.
