The lines that <span>support the idea that Macbeth does not want to tell his wife about Banquo's murder until after it has been done are the following:
</span><span>A."Be innocent of the knowledge, dearest chuck, / Till thou applaud the deed."
The lines mean - It's better for you not to know about this until you see the results.</span>
I'm assuming the underlined word is exercise; I believe the correct definition of exercise in the sentence "Jorge completed the economics exercise before the rest of his team" is B: A task done to practice a skill.
<em>If this is incorrect, please, don't refrain to tell me. Thank you. </em>
