50 ! no which words in the sentence form the participial phrase? the boy grinning from ear to ear is my mischievous little brother. a. is my b. grinning from ear to ear c. the boy d. mischievous little brother

Well, since grinning from ear to ear is an idiom, and that no one can do that, that will be your answer (I actually did this on my test, so I know the answer. A is wrong, because it just says is my, C is wrong, because there are boys, but it is not a participal phrase, and D is just talking about the boy's characteristics.

So your answer is B. grinning from ear to ear.

Hope this helped!
