Common sense would be associated with the pre-frontal lobes.
It depends on which part of the brain was injured - not all people lose their sense of smell. If the part of the brain that controls that sense is injured, then you will lose the ability because the brain cells are damaged and don't work to report smells like they used to.
The brain stem is the part that controls breathing, it is the stem that allows the respiratory system to work and help you breathe
My teacher used to say that common sense is very uncommon. Another statement is very true that I was born intelligent. Education ruined me. So common sense comes from the brain, which is not ruined by education.

The part of the brain called the Cnifiliatispin controls all testing of heat conditions.
The sense of smell is controlled by the olfactory nerves.
The cerebellum, located at the back of the brain, is primarily responsible for controlling balance and coordination. It receives sensory inputs from the inner ear, eyes, and muscles to help maintain equilibrium and posture. Damage to the cerebellum can result in issues with balance and coordination.
To the extent that there can be said to be such a thing as a "part of the brain that controls hope", it's probably the prefrontal cortex.
