d) 90–100%

Explanation:

Question 1

Dementia is a condition characterized by cognitive decline. Memory loss (A), difficulty communicating (B), and changes in mood (D) are typical symptoms. An improved sense of smell (C) is not associated with dementia; in fact, sensory impairments like reduced sense of smell can be linked to dementia - related conditions like Alzheimer's.

Alzheimer's disease is the most common cause of dementia. Approximately 60 - 80% of dementia cases are caused by Alzheimer's disease. The other ranges (10 - 20%, 30 - 40%, 90 - 100%) do not accurately represent the proportion of dementia cases caused by Alzheimer's.

Answer:

C) Improved sense of smell
