I'm busy with writing some news stories which will be put in the newspapers at random moments. This are mostly natural events which are not controlled by humans.

These events will affect the market prices. In a further version, they might even affect your company!

Here is an example of what could possibly happen:
[i]There was a big storm last night and many of the roads got flooded which makes it impossible for the suppliers to deliver their goods to the market.

The government is trying to do all they can to make the suppliers deliver their goods. A team has been sent for help, but they were not in
time to get the goods on the market for today.

As a result, the prices of all the goods have risen.[/i]
