As per STCW, any crew having consumed alcohol within ______ shall not serve as a member of a watch.
A. one hour
B. four hours
C. two hours
D. three hours
题目解答
答案
B. four hours
解析
本题考查对STCW（《国际海员培训、发证和值班标准公约》）相关规定的了解。解题思路是明确STCW中对于饮用酒精后不能担任值班船员的时间规定。
根据STCW的规定，任何在四小时内饮用过酒精的船员不得担任值班人员。所以我们只需要依据这个规定来选择正确的时间选项。
