How should Mark adjust his behavior to be a more effective discussion participant? Select two options
He should address the topic with Louise after the
discussion.
He should keep the discussion on schedule by moving
to the next topic.
He should ask a question to clarify the cost of the
scoreboard.
He should raise his hand to indicate that he wants to
enter the conversation.
He should take notes reminding himself to do research
on shipping times later.

He should keep the discussion on schedule by moving  to the next topic.

He should raise his hand to indicate that he wants to  enter the conversation.

Explanation:

In these two scenarios Mark is actually participating and/or adding to the discussion. All the other scenarios are just for clarification or what to do after the discussion. Clarification is not participating
