What type of sentence is it? What members of sentence are here?
It(song) was no strain on the voice, and I guessed that Margaret knew what she was doing when she chose it.
My observations: It's a compound sentence.There are 5 clauses:1) It was no strain on the voice, 2) I guessed 3) that Margaret knew, 4) what she was doing, 5)when she chose it.
1)It - formal subject.
Was no strain - the compound nominal predicate
On her voice - the prepositional object.
2) I - simple subject
guessed - simple predicate.
3) that Margaret knew - is it some kind of object clause?
Margaret -simple subject.
Knew - simple predicate
That - ?
4)what she was doing - object clause? What does it consist of?
Was doing - simlpe verbal predicate(past continious)
What - ?
5)when she chose it - adverbial clause of time.
She - subj,
Chose - predicate,
when - ?
