Question

Which line from "Helen Grey" implies the author thinks Helen's behavior is going to hurt Helen herself? (4 points) Because one loves you, Helen Grey / Is that a reason you should pout Don't cut your fingers with the edge / Of your keen wit; Stoop from your cold height, Helen Grey / Come down, and take a lowlier place Come down you must perforce some day / For years cannot be kept at bay

Answer 1

I would say that the line which implies the author thinks Helen's behavior is going to hurt Helen herself is Don't cut your fingers with the edge / Of your keen wit.
Because her mind and behavior are going to hurt her, or rather make her hurt herself.

Answer 2

The line from Helen Grey, which implies that the author thinks Helen's behavior is going to hurt herself is this: DON'T CUT YOUR FINGER WITH THE EDGE OF YOUR KEEN WIT.

Cutting one's finger implies hurting oneself or doing harm to oneself. When a man is said to have a keen wit, that means that, that man has a very sharp intelligence. So in the line given above, what the line is saying essentially is that 'Helen should not hurt herself with her sharp intelligence'.
