Why might it be a good idea to have a rule during classroom discussions that
each student may have 30 seconds to prepare a response to a question that
has been asked?

Explanation:

It would be a good idea that way they can develope questions faster. It can also help allow everyone to have a chance of talking. It also makes the person to think and develope what they are going to say before they say it.

for example: in, he, a,from

it u understand what he thought at the time and let u know more about him then what third person would of known probably. hope this : )
