I've come across an intriguing problem while grading a student's work. She wanted to discuss the feeding ground of a whale pod. The original sentence reads "the pod of whales feeding grounds."
My initial reaction was to advise changing it to "the feeding grounds of the pod of whales." However, this feels overly repetitive regarding "of."
Is there a way to correctly punctuate "pod of whales" with an apostrophe to make it possessive?
