Answer 1:
Based on the passage, the doctor has learned that Lady Macbeth's condition is beyond his medical expertise, and that she needs spiritual or divine intervention rather than physical treatment. The doctor comments that "This disease is beyond my practice" and "More needs she the divine than the physician". Therefore, the correct option is: She needs a priest and not a doctor to cure her ills.
Answer 2:
The phrase that best describes Caithness and Lennox as they march towards Birnam is "Dutiful Obligation". They are marching to fulfill their duty to their country and their rightful king, Malcolm, who is leading the rebellion against Macbeth's tyrannical rule. The lines "To give obedience where 'tis truly owed" and "Make we our march towards Birnam" suggest that they are following orders and fighting out of a sense of loyalty and obligation to their cause, rather than out of personal anger or guilt. Therefore, the correct option is: Dutiful Obligation.
