Question

the mumps and herpes simplex viruses are common examples of

○ bacterial infections

○ diseases that usually cause brain abscesses

○ viruses that have a particular affinity for brain tissue

○ viruses that can attack the brain but do not have a particular affinity for brain tissue

○ cerebral tumors

Explanation:

Mumps and herpes simplex are viruses. Brain abscesses are usually caused by bacteria. Some viruses (like rabies) have affinity for brain tissue, but mumps and herpes simplex can affect the brain (e.g., encephalitis cases) without a specific "affinity" as their primary target isn't the brain initially. Cerebral tumors are not viral infections.

Answer:

viruses that can attack the brain but do not have a particular affinity for brain tissue
