Final answer:
The speaker admires the librarian, Mrs. Long, and appreciates all the efforts she made in providing books that were meaningful to the speaker. However, the given excerpts do not provide sufficient evidence to confirm that the library was a safe haven or whether the librarian was particularly happy to see the speaker.
Step-by-step explanation:
In response to the student's query, the speaker clearly holds Mrs. Long, the librarian, in high regard, both admiring and appreciating her. The student has accurately identified that the speaker admires the librarian, acknowledging the librarian's friendly nature and the effort she put forth to supply the desired books, which played a significant role in the speaker's life. Hence, a) and d) are appropriate choices that should be included in the response. While statements b) and c) may seem relevant, they are not explicitly supported by the presented excerpts. Lastly, statement e) is inconclusive without further context indicating the librarian's happiness to see the speaker.
