Answer: B. the fragile nature of existence
Explanation:
The two excerpts are from "A Portrait of the Artist as a Young Man", by James Joyce, and from "Mrs. Dalloway," by Virginia Woolf. Both share the common theme of the fragile nature of existence. Woolf describes a character that is wondering about her own existence, and its importance or the possibility of her life not being important, as "all this must go on without her." Both excerpts show ideas about the fragile nature of existence, not the absence of love, nor reality or disillusionment with the world.
The answer is B what effect is the writer trying to create by using this language

It is a more realistic view of what the "dream" actually looks like in practice.
