@fresco,
It's from "The Grammar Dog guide to Christmas Carol by Charles Dickens", it's used by some high schools in the United States. That sentence along with others is in an exercise to determine whether a sentence is Simple, Compound, Complex, Compound Complex. The answer sheet states it's a complex sentence.
My issue is where does the Independent Clause begin and end.
He went to church, and walked about the streets, and watched the people
hurrying to and fro, and patted the children on the head, and questioned
beggars, and looked down into the kitchens of houses, and up to the windows,
and found that everything could yield him pleasure.
"He went to church" is an independent clause as it contains a subject and verb and is a complete thought.
"that everything could yield him pleasure" is a dependent clause as it contains a subordinate conjunction (that) and also subject (everything) and verb phrase.
BUT "He went to church, and walked about the streets, and watched the people hurrying to and fro, and patted the children on the head, and questioned beggars, and looked down into the kitchens of houses, and up to the windows, and found"
seems rather awkward and an incomplete especially how it concluded "and found"
