Read the following Passage From the Poem "Eve To Her Daughters."
It was not I who began it
Turned out into draughty caves
hungry so often, having to work for our bread
hearing the children whining
I was nevertheless not unhappy.
Where Adam went I was fairly contented to go.
I adapted myself to the punishment: it was my life.

Which word best describes the speaker's tone in these lines?
A: Blunt
B: Doubting
C: pessimistic
D: sarcastic

We use sarcasm when what we say is exactly the opposite to what it's happening, or to what it is, and is used to mock someone else' views, to hurt someone indirectly or to express an unpleasant situation that is harder to say in another way.

In the excerpt, this kind of remark is what the speaker is using. In reality, the speaker does not mean that they were happy to the way they were living: in draughty caves, hungry so often, hearing the children whining, neither do they mean that they adapted to that way of living (Who could be happy and adapt to that way of living!?). The speaker indeed suggests exactly all the opposite, but since it was just such an unpleasant and bitter situation for them, they could not find any other way to express it than with sarcasm.
