Final answer:
The weight percentage for the 'wording and grammar criterion' cannot be determined without the specific grading rubric context.
Step-by-step explanation:
The specific data required to answer the question regarding the weight percentage for a "wording and grammar criterion" is not provided in the given information. However, it appears that the question is related to a grading rubric found in a school or educational context, where different criteria are assigned different percentage weights for evaluation purposes. If we look at the rubric hint provided, which indicates that "Answers are worth 25 points each", we might infer that each aspect, such as wording and grammar, could potentially have a significant weight. However, without specific instructions from the rubric stating the weight of the "wording and grammar criterion", it isn't possible to determine the correct percentage from the options provided, as each option is a guess without the proper rubric context.
