Adjective Clauses Omitting the relative pronoun by tesolthis

This is a Kahoot quiz I found on omitting the relative pronoun from relative clauses.  (It's labelled as "adjective clauses" but I think that's just another name for "relative clauses".

I used this in my classroom, and it worked well.

A note of caution, however, for any teacher who wants to use this in their own class.  I usually teach my students that relative clauses can only be omitted if they are in the object position.  This Kahoot caused me a bit of trouble, because number 8 and number 10 contain relative pronouns that can be omitted, but they are not in the object position.  ("The scene was so beautiful that it made me cry" and "This is the place where I had my first kiss".)  Obviously there are some additional rules about omitting the relative pronoun that I must be unaware of.  If you know these rules (and can explain them to your class), then it shouldn't be a problem.  

Otherwise, if you're like me and you don't want to open that can of worms, then I made a duplicate of this quiz, in which I deleted number 8 and 10.  And then, to pad out the quiz, I added in some extra questions of my own from this worksheet here.
