Be _____ of obvious things and _____ of persons quick to produce identification or alibis.

The correct choice is significant because it utilizes the terms "cautious" and "wary," both of which express a vigilant and careful approach in the context of the statement. Being "cautious" implies being careful to avoid potential problems or dangers, which is essential when evaluating obvious situations. It highlights the need for attentiveness to one's surroundings and the potential for unexpected outcomes or threats.

The word "wary" complements this by indicating a sense of caution in regard to individuals who may be quick to produce identification or alibis, suggesting a need for skepticism when such behaviors are exhibited. Individuals who are overly eager to provide validation could be concealing their true intentions or actions. Thus, being both cautious and wary encourages a mindset of critical assessment and careful evaluation in situations that may pose risks or require deeper scrutiny.

For example, "aware" does imply a recognition of one's surroundings but lacks the nuance of being actively cautious about them. Additionally, "skepticle" appears to be a misspelling of "skeptical," which undermines the clarity of the statement. Therefore, choosing "cautious and wary" effectively communicates the
