In the sentence: "They help poor families", how do we make a question which the answer is "poor families"?
Back in school they taught us that we should use "do" while forming a question in present simple unless the question is asking about the subject. In this example, we say: "Who help poor families?" But in the case where you want to ask the question where the answer is "poor families", you normally say: "Who do they help?" _at least they way they taught us. However, I noticed somewhere that they used the following structure: "Who they help?"
I wanted to see if I'm missing a grammar or something? Or maybe it is common in speaking and informal writing. Any help in here would be appreciated.
