Answer:
A. Details that the author uses to create a feeling about the setting:
The wind blows so hard that seems like it could flake away their identities. The martian air seems able to draw their souls away,
to dissolve the intellect and burn away their past. The hills are characterized as having been under the crushing pressure of time, and old cities are described as similar to children's bones.
Explanation:
B.
The author creates a negative feeling about the setting through the use of images and metaphors that are macabre and unsettling, such as an environment that can take away their identities, their souls, their intellect, and even their past. The reference to children's bones is probably the most unsettling element and the one that makes it clear that the setting is not a welcoming one.
