Final answer:
The author describes a land of beauty and unique features surpassing others in wonders, but does not mention his sister's navigation skills. The correct answer is option (A).
Step-by-step explanation:
The author describes all of the following except (A) His sister’s navigation skills. The passage does not provide any indication of the sister's navigation abilities. Instead, it describes a land of beauty and uniqueness, surpassing all others in wonders. It also mentions a possibility of traits without example and muses about the phenomena in undiscovered places (solitude). Thus, options B, C, and D are mentioned but option A is not described in the text.
