Anew website called “earthray. org” discusses whether or not alien life exists. using mla style, what is the correct format for a web address in a works cited entry?

The correct format would include the name of the author, the name of the paper, the publisher, the date when it was posted online, and the link. The date is important because websites change so if someone's checking for plagiarism they can call the website owner and see what the page was like on that day that you provided.

Walked would be the participle here. as it is a verb ending in -ed.
