Shady is the adjective in the sentence.
I think it's B) because a missing modifier is when a sentence is broke apart incorrectly and I don't think that B) is correctly separated. I could rearrange the sentence and make it say, "The thunder frightened me as I slept peacefully" and it would sound better. I hope I helped a bit.
I assume that P -2 4 q 6 -2 means the two points that you are trying to find the midpoint to are meant to be coordinates.
This would mean that you would need to find the midpoint or point in the center on the graph.
You would need to use the midpoint formula (x1+x2)/2 and (y1+y2)/2
The answer would therefore be the coordinate (2,1)
I believe the answer is many worms or worms. This is because the action is applying to them.
