Hi, you've asked an incomplete question. However, I answered from a general English Language perspective.
<u>Explanation:</u>
Things learned about communications:
1.  No communication occurs when what is been said cannot or is not been understood.
2.  Communication also occurs non-verbally, like when one shows a friendly smile without a word, it as though they are saying, I'm happy with you.
Two strengths that you think you have in communication:
1.  I'm a good listener
2.  I can ask a lot of questions.
Two weaknesses that you think you have in communication that you  can improve in the future:
1.  My use of ambiguous language that is difficult for my listener to understand
2.  Not giving total attention to the speaker.
Challenges: Share two things that you find very challenging in effective communication.
1. avoiding pre-conceived judgments about what is been said
2. giving the desired feedback without derailing from the subject that is been discussed.
