Answer:
<em>398 deaths were caused by Alzheimer.</em>
Explanation:
Proportionate mortality rate (PMR) gives the proportion of deaths in a given population over a period of time, this can be linked to various causes.
Mathematically PMR is reoresented below;
PMR =
X 100
where
= No. of death from a specific cause (In our case Alzheimier )
= Total No. of death at a given period
from the question the parameters were given except the number of death from Alzheimier
1.87 =
multiply both side by 21,270 to isolate 
= 1.87 x 21,270
Divide both side by 100 to obtain 
= 
= 397.749
since dead people can not be divided

Schachter-Singer two-factor theory
Explanation:
A polygraph is a lie-detector test which uses certain devices and procedure to measure or record various physiological parameters like blood pressure, heart rate, respiratory rate, skin conductivity etc at the same time when the subjective person answers to a series of questions asked.
The principle is that a person’s or examinee’s physiological or clinical parameters like blood pressure or heart rate can accelerate, stay stable, or may even go down in response to the questions asked. Depending upon these changes, the examinee can be assessed whether he/she is telling a lie or truth about something asked.
The Schachter-Singer two-factor theory of emotions states that emotions are dependent on two factors – physiological arousal and cognitive label.
According to this, an environmental stimulus gives rise to a physiological reaction or arousal which then leads to cognitive appraisal of the emotion.
Thus the theory of polygraph is based on Schachter-Singer’s emotional theory.
