Answer
# 1		 
Render Variables are generally created to conditionally
render a particular page or chart or list o block. The
purpose of the render variable is to hide a particular item,
we cant say it used to hide particular item.
When we  are using render variable only the queries which
satisfies the parameters will be rendered and hence the
other queries will not be processed in back end by cognos.
