Correct Answer: the role of amyloid precursor protein in Alzheimer's disease.
Why this is correct: After prevalence figures, the report focuses on amyloid precursor protein and its possible role in Alzheimer's disease. It describes an unresolved question and proposed theory, not a proven cure.
Why the other options are wrong:
- new drugs already proven to cure Alzheimer's disease.: No drug is reported as a proven cure; the account concerns a protein's possible role.
- Alzheimer's disease only in children.: The report is not limited to children and discusses Medicare beneficiaries and disease mechanisms.
- the elimination of Alzheimer's disease worldwide.: The disease is reported to affect many people, not to have been eliminated worldwide.
Correct Answer: Florida.
Why this is correct: The report attributes to the Alzheimer's Association the statement that Florida ranks first in US per-capita cases. This asks what the report says rather than certifying a current ranking.
Why the other options are wrong:
- California.: California is not the state named in this reported ranking.
- Massachusetts.: Massachusetts is not the state identified; the report names Florida.
- Montana.: Montana is not identified as number one in the report.
Correct Answer: thinking and behavior.
Why this is correct: The report lists changes in thinking and behavior alongside memory loss.
Why the other options are wrong:
- skin tone and color.: Skin tone and colour are not the changes listed with memory loss.
- body pain and strength.: Pain and strength are not the named pair of changes.
- hearing and tasting ability.: Hearing and tasting are not the functions named; thinking and behavior are.
Correct Answer: amyloid precursor protein
Why this is correct: The researchers' unresolved question names amyloid precursor protein as a possible mastermind or conspirator. Identifying its subject does not establish that this protein causes the disease.
Why the other options are wrong:
- multivitamin deficiency: Multivitamin deficiency is not the subject of the quoted mastermind-or-conspirator question.
- calcium deficiency: Calcium deficiency is not named in that question.
- a cholesterol-transporting protein: The cholesterol-transporting protein is discussed separately as a genetic risk factor; the question specifically names amyloid precursor protein.
Correct Answer: the highest genetic risk factor
Why this is correct: For the more common form of the disease, the report names a cholesterol-transporting protein as the highest genetic risk factor. It does not claim cholesterol accumulation or a cure.
Why the other options are wrong:
- proof of a calcium deficiency: The reported role is a genetic risk factor, not proof of calcium deficiency.
- a marker of poor hearing: Poor hearing is not the role attributed to this protein.
- a guaranteed cure: A risk factor is not a cure; no guaranteed cure is reported.
