In class discussions, do you ask more than one question at once?

not all time

No .j ust ask one  question  and wait for   a period of reflection and answer 

It depends on the topic dealt

yes , if i found the students can answer them , i can ask to make them asure of the information

It depends.

Yes, and it serves more than one purpose.

I can ask more than a question if they are concerned together or to make it such a serial of questions that leads to revision,like I make a question on present simple and ask can I use it in conditions , in which one, what is it concerned for?and so on you will make it tasty and varied.

I prefer to ask one question that, when answered, will lead to another question or to indepth discussion.
