Ghlight the text you want to be the link and then click the icon that looks like a chain "link". I'm assuming that is your trouble, that you weren't sure which one was the link icon.
By the way, the broken chain link is how you delete a link.
Ghlight the text that you want to be made into a link, then click on the link icon in the editor to enter the url you want the text to link to.
Or, you can lookup the following w3schools.com/HTML/html_links.asp.
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.
