Answer:
Jane's obsession with the Gulliver's Travels book and Bessie's song indicates the character of the narrator.
Explanation: The excerpt mentions a narrator who is presumably Jane herself who talks about Bessie who is her nursemaid and who fetches the Gulliver's Travels book for Jane which Jane loves to read very much.
Jane dreams about the places mentioned in the book and the various strange plants, animals and people which are discovered by Gulliver on his fictional voyage to the different islands.
She also pays attention to the song that Bessie sings and on her sweet voice but how the song now feels like a refrain and not a joyful song.
The correct answer is A. It starts with very specific details, devoid of any emotional interfering on the narrator's part. The only subjective detail in this line is the estimation "very strange". Still, it doesn't disturb the factuality of the context, which is firmly rooted in precise time and place references.
