Answer:
2. b) Don't speak clearly and precise
3. a) Withdrawal, taboos, and or difficulty hearing
Explanation:
Question 2 is not a strategy of effective dialogue because effective dialogue includes speaking clearly.
Question 3 is basically asking, what are some flaws or problems when speaking. The answer is withdrawals, taboos, and difficulty hearing because all three of these items are a problem when trying to create conversation.
Speaking clearly is a very big factor in effective dialogue for if you cannot speak clearly, you would be mumbling and the other person wouldn't be able to understand you, leading to an ineffective conversation/ dialogue.
Difficulty hearing can result in a lot of, "what?", "can you repeat that?", or "come again?" in a sentence, which can result in having to repeat yourself often to that person, resulting in a less effective conversation.
