The text states that “this level of detection of such risk factors could equate to the prevention of over 2,000 heart attacks and strokes”. However, it further goes on to say that the researchers did not go on to monitor the health of those identified as having such risks.
We, therefore, cannot be sure whether 2,000 heart attacks or strokes were prevented or not.
A – Wrong
This does not fully justify the spending of resources as we do not know whether the health checks were effective or not as we do not know whether 2,000 heart attacks were prevented.
B – Wrong
We cannot conclude this as the researchers did not monitor the people’s progress and hence we cannot say whether the screening helped to influence people’s health related behaviours.
C – Correct
Since the researchers did not go on to monitor the health of those identified as having such risks, we cannot be sure whether 2,000 heart attacks or strokes were prevented or not.
D – Wrong
Since we do not know whether the screening was effective or not, we cannot justify the expenditure of resources on long-term outcomes of individuals.
E – Wrong
Other age groups are not mentioned in the text, so we cannot infer this information.
