A.The material it was made from had never been seen before.B.It was much older than previously thought.C.It was cut sideways instead of lengthwise.D.Money did not exist in Africa then.

A.seek new sources of readershipB.end the print edition for goodC.aim for efficient managementD.make strategic adjustments
