Question

Please show a diagram. The question is quite vague. 
What is a single support beam and continuous beam?

Hahaha lol
When you don't even know what is Support Beam and Continuous Beam, why have you even bothered to answer this question..!!
Google it... and there's no diagram.

So your question is to ask why do we choose to support a beam of length 5, with another horizontal beam instead of a vertical one?
