If Susan is uncertain about the meaning of "mark," what should she do?

Choosing the first definition as the primary meaning of "mark" is not necessarily the best approach to take when uncertain about the term's meaning. The word "mark" can have multiple definitions that depend heavily on the context in which it is used, such as being a symbol, an indicator, or a grade.

Instead, a more effective method would involve examining the context in which "mark" appears. This would guide Susan to identify the most relevant definition. Context clues can provide critical information that highlights which meaning applies. For instance, if "mark" appears in a sentence related to grading, it likely refers to a score or evaluation, while in an artistic context, it may pertain to a line or symbol.

It is beneficial for Susan to consider a range of definitions and analyze how they relate to the surrounding text to arrive at the correct interpretation. This approach ensures a more nuanced understanding, allowing her to select the definition that most accurately reflects the intended meaning.
