1. Read the passage and answer the following question.
The world’s first blood test to predict Alzheimer’s disease before symptoms occur has been developed. The test identifies 10 chemicals in the blood associated with the disease two to three years before symptoms start, but it might be able to predict Alzheimer decades earlier.
Globally, 35 million people are living with Alzheimer’s. It is characterized by a toxic buildup of amyloid and tau proteins in the brain, which destroys the neurons. Several blood tests can diagnose the disease, but until now, none has had the sensitivity to predict its onset.
But with no treatment available, would anyone want to take these tests? Mapstone says “In my experience, the majority of people are very interested to know whether they will get Alzheimer’s. They believe that knowledge is power- particularly when it comes to your own health. We may not have any therapy yet but there are things we can do- we can get our financial and legal affairs in order, plan for future care, and inform family members.”

A. Two or three years before the illness begins
