Answer:
Step-by-step explation:
In addition to the name clues, the order clues (ahead/behind) are also helpful. The above answers are listed in order, with Lily (or Karen) being first and Grace being last.
The only "Miss" in the group is Miss Isaacs, so Pamela, who has never married, must be Pamela Isaacs. Grace was behind 3 women, so must be last. Miss Isaacs did not see the oriole, nor the cardinal or indigo bunting, so must have seen the scarlet tanager.
The women who saw the cardinal and indigo bunting were the first two, so Grace saw the oriole. She was not Ms Baker or Ms Wellington, so must have been Grace Halliday.
Karen was not Ms Wellington, so must have been Ms Baker. Then Lily was Ms Wellington. She had not seen an indigo bunting, so Lily Wellington saw the cardinal, and Karen Baker saw the indigo bunting.
