B. The time required to become proficient after repeated use C. The satisfaction rating after the first task D. The percentage of users who can complete a task on the first attempt Answer: D Explanation: Learnability focuses on how quickly new users can perform tasks correctly on initial exposure. Question 30. Which of the following statements about “error tolerance” is true? A. The system should prevent all user errors at all costs B. The system should allow users to recover easily from errors C.
