Final answer:
Lord Capulet in Romeo and Juliet is best known for his authority and volatility, and the question seems to be missing specific traits to identify which he does not exhibit.
Step-by-step explanation:
In William Shakespeare's Romeo and Juliet, the character of Lord Capulet is complex, exhibiting several characteristics, including authority and volatility. However, among the traits presented in the query, Capulet does not typically showcase heroic attributes or indicate when a positive trait becomes a tragic flaw. Rather, those are broader themes explored within Shakespeare's works and other literature. The traits that Capulet explicitly does not display would not be relevant to this discussion since they are not provided in the question.
The Nurse, as mentioned, serves as a foil to Juliet, highlighting the youthful innocence and passionate nature of Juliet in contrast to the Nurse's practical and experienced views on life and love. Additionally, when considering a character's traits, the performances by actors, as referenced in the provided information, can bring a new dimension to these characters, interpreting Capulet's anger and authoritarian demeanor in ways that resonate with the audience, regardless of the historical language barrier.
To answer the student's question directly, without the specific traits listed for Capulet, it is challenging to discern which two attributes he does not exhibit. Instead, the student can reflect on Capulet's overall representation in the play, considering the thematic elements such as love and parental influence, which are more prominently on display.
