What's the sentence structure of the following sentences: (between simple, compound, complex, compound/complex) ps. if there is any punctuation required please write it.
1) Though I had not known why he was absent, I had been glad that he was not there to shout his restrictions at me.
2) They came toward me and I broke into a wild run toward home.
3) Granny's home in Jackson was an enchanting place to explore.
4) I realized that they could not understand what I was felling and I kept quite.
5) I had begun to notice that my mother became irritated when I questioned her about whites and blacks, and I could not quite understand it.
Also I would really appreciate it if you could briefly explain why they're that structure.
Thanks
