Answer:(1) I will examine the paper and the ink used, possibly with the use of LIGHT or some chemical substances.
(2) I will examine the style of writing because writing style has been known to change from time to time.
Explanation: I will examine the paper to determine if the paper is old is one of the aspects and ways to go about it. It is known that recent paper quality is better or will look new when compared to the papers used fifty years ago. I will also examine the ink used to know if it is a recent ink or the one used about fifty years ago. This can be done using Light to view or some chemical substances to determine how old the ink is.
Style of writing has been known to change,so I will examine the style of writing to see if it is similar to that of modern times.
