Hello professor, Hope your day have been great so far.
I am studying Lesson 5 at the moment and i have another question.
I've learned 4strategies and I've thought the advantage and disadvantage involved with those 4 strategies and 5 questions.

When it comes to "strategy A", this strategy is that the teacher asks a question and then lets students shout out the answer together.

Amonst 5 questions, question 5 is "Does it give lazy students a chance not to answer?". And we have checked an X in the class, right?

I don't understand well on this part actually. Because if everyone shouts out when the teacher asks a question, it'd be nice chance to not answer for lazy students isn't it?
So i thought the answer is O.

So my question is that an X and O mean just Disadvantage and advantage? I know you've said an X means bad for that and O means good for that.
But i don't get it very well. I would really appreciate if you make me understand this part.

Thank you so much :)
