Sergeant
Our police academy no longer requires its applicants to pass a physical examination before being admitted to the academy. As a result, several candidates with weak hearts arid high blood pressure have been admitted. Hence, we can expect our future police force to have more health problems than our current police force.
Knowledge of each of the following would be relevant to determining the reliability of the sergeant’s prediction EXCEPT whether
A．police officer candidates are screened for high blood pressure before joining the police force.
B．the police officer candidates who are not healthy now are likely to be unhealthy as police officers.
C．graduates of the police academy are required to pass a physical examination.
D．the health of the current police officer candidates is worse than was the health of police officer candidates in the past.
E．(E) a police officer’s health is a reliable indicator of the officer’s performance.
