            When the government of a nation announced recently that a leader of the nation’s political opposition had died of a mysterious illness in prison, few seasoned observers of the regime were surprised. As the police captain in an old movie remarked when asked about the condition of a prisoner, “We’re trying to decide whether he committed suicide or died trying to escape.”

The statements above invite which of the following conclusions?

(B) The opposition leader may not be dead at all.

(C) It is unlikely that the head of the regime knows the true cause of the opposition leader’s death.

(D) The opposition leader probably killed himself.（E）

(E) The regime very likely was responsible for the death of the opposition leader.
