Need to better organize the content. Don't talk a lot for one reason. Try this pattern for Q1-Q2:

first 1-2 sentences: introduction. my opinion: A or B. agree or disagree. about 5-10 seconds

First, reason 1 (1 sentence) + why reason 1 (some arguments. 1-2 sentence) + a small conclusion for reason 1(like advantages of reason 1 or comparisons if not reason 1, 1-2 sentence). // about 15 seconds

Second, reason 2 (1 sentence) + why reason 2 (some arguments. 1-2 sentence) + a small conclusion for reason 2(like advantages of reason 2 or comparisons if not reason 2, 1-2 sentence). // about 15 seconds

Conclusion: Don't need a conclusion. (you can have one only when you don't have something to talk about)
