Final answer:
Lord Capulet respects Juliet's free will in her marriage choice, as evidenced by his lines in Act I My will to her consent is but a part; An she agree, within her scope of choice, Lies my consent and fair according voice, where he says his will is only part of the decision and that Juliet's consent is important.
Step-by-step explanation:
The lines in the excerpt from Act I of Shakespeare's Romeo and Juliet that suggest Lord Capulet respects free will are:
My will to her consent is but a part;
An she agree, within her scope of choice
Lies my consent and fair according voice.
These lines indicate that Lord Capulet believes his daughter Juliet should have a say in her marriage and that her consent is critical. He acknowledges that his own desires are not the only thing that matter and that he will respect Juliet's choices and willingness to consent. In stating that his will is only a part of the equation, he shows a more progressive attitude towards marriage and his daughter's independence compared to the norms of the period.
