You've mixed procedural and object-oriented MySQLi styles. This has led to you trying to use the functions like mysqli_query($mysqli) instead of the member functions like $mysqli->query() . Your $mysqli is an object not a resource handle.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
