In this task, you're given a statement and three sentences as choices. Your job is to determine which sentence can be inferred from the statement. Incorrect choices change the meaning in important ways or have details that are not mentioned in the statement. Indicate your answer as 1,2, or 3 corresponding to the choice number of the selected sentence.

Statement: The first challenge for implementing recommended screening and interventions for problem drinking in emergency settings involves convincing staff of the importance and efficacy of such interventions. Choices:  1. The first problem for finding problem drinkers is getting all the patients to understand interventions. 2. The first problem for finding problem drinkers is getting all the staff to understand interventions. 3. The first problem for finding problem drinkers is getting all the staff to understand interventions in the ED during a trauma.

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
