Before before beginning an internet search to find supporting information for your topic, you must know

Hi there! So your question was, "Before beginning an Internet search to find supporting information for your topic, you must know." The answer to this is, you must know, (what type of information you're looking for).  For example you need to make sure you know what to search up before you go and dig stuff up from the internet, which in this case, if you dig up something it may not or it may be false!

Hope this helped!! <3
