Question 7

1. Look at the URL of the site. If it has gov it is a government site. If it has org it is an organisation web site. There may be an author of the site. If their address seems to link with the 'authority' of the site, it may be correct. For example, if the web master had an address of is for Israel in their address, it was probably an Israeli site. The web design and layout have no influence on the authority of the site.

2. 1. Any program which you download must be scanned before executing, do not open attachments from strange sources, be aware that a Word or Excel file attachment may contain a Macro virus.
