Write a short paragraph expressing your ideas about the chinese and silk prodution. why do you think they so carfully guarded the secret of how to produce silk

Since the Chinese where the only ones who could make and sell silk, they could get a high price for their special cloth. If they had simply given their secrets away, it would have been commonplace for everyone to make, and the Chinese would have lost their giant income from the silk buyers. It would also have put many people out of a job, like the silk merchants/traders! 

explanation: we can only guess at how our actions may be perceived in the future. doing something really big like killing lots of people, saving lots of people, affecting the lives of lots of people is a sure fire way of being remembered in historical records. we can also make a difference in the history records by being a small influence on something bigger, whether that is as a civil servant, scientist or artist.

of course you could argue that we all affect history just as tiny cogs in a   bigger machine.

if you mean how do people influence our opinions of things which have already happened, then simply by writing a book which looks at things form a different perspective and trying to convince people that this perspective is more accurate or truthful. people do it all the time i.e. richard the third was a terrible or was he? plenty would disagree, it's just that their views aren't the most widely known.n:
