本题考查对船舶垃圾处理相关规定的知识以及对句子逻辑关系的理解。解题思路是根据题目所描述的食品废弃物排入大海的许可条件,分析各个选项与规定的匹配度。
- 首先明确题目说的是食品废弃物排入大海被允许的情况,条件是要经过某种处理并且通过开口不大于25mm的筛网。
- 选项A“through a comminuter”,只提到了经过粉碎机,没有考虑到还可能是磨碎机,表述不全面。
- 选项B“through a grinder”,只提到了经过磨碎机,没有考虑到还可能是粉碎机,表述不全面。
- 选项C“through a comminuter or grinder”,表示经过粉碎机或者磨碎机,符合规定中可以选择其中一种设备进行处理的情况,是正确的。
- 选项D“through a comminuter and grinder”,表示要同时经过粉碎机和磨碎机,这与规定不符,规定是选择其中一种设备处理即可。
