It's about subordinate clauses. It states on the sheet that a clause must always have a verb in it.
It then gives the following example of two one clause sentences being joined to make a two clause sentence:
"The monster looked scary. He looked angry."
"The monster looked scary and angry."
I don't see how this is a two clause sentence, if a clause has to contain a verb.
There's also an exercise where you have to under line the main clause and the subordinate clause. One of the sentences is:
"Joan picked up the first prize and the best-groomed horse award."
Again, how is this two clauses?
Am I missing something?
