A. Check the fluid prior to mixing.
B. Prior to checking the fluid, ensure it has been mixed.
C. Never mix the fluid before testing.
解析：这道题考察的是在检查新液体之前应该进行充分混合的原则。正确答案是B:Prior to checking the fluid, ensure it has been mixed.
解析：在检查新液体之前，首先要确保它已经被充分混合。如果液体没有被充分混合，可能会导致检查结果不准确，影响后续的使用效果。因此，在进行任何检查之前，都应该确保液体已经被充分混合。
举个生动的例子来帮助理解：就好像做蛋糕一样，如果在混合面粉、鸡蛋和牛奶之前就开始检查其中的某一种食材，那么最后做出来的蛋糕可能会出现问题。只有在所有食材都充分混合之后，才能够准确地检查蛋糕的质量。所以在检查新液体之前，也要确保它已经被充分混合，这样才能够得到准确的检查结果。
