The two quotations that support the inference that Margaret had reason to fear Mrs. Jack are:
-
"There was never much love lost between her and Margaret, and Mrs. Jack's guesses were perhaps the most ill-natured as to the reasons for Margaret's silence and her curious, checked clothing." (paragraph 4)
- This indicates a negative relationship between Mrs. Jack and Margaret, suggesting that Mrs. Jack makes hurtful speculations about Margaret, which could lead to Margaret fearing her.
-
". . . Mrs. Jack noticed that the dinners were putting a roundness on Margaret that might give her a new lease on life--perhaps not a desirable result." (paragraph 7)
- This suggests that Mrs. Jack may have ulterior motives or negative feelings toward Margaret's well-being, which could instill fear in Margaret regarding Mrs. Jack's opinions or intentions.
Together, these quotations demonstrate a basis for Margaret's fear of Mrs. Jack due to their antagonistic relationship and Mrs. Jack's harmful observations.
