a)
I like this presentation because it is simple and the rate of speed is enough to catch up.

b)
Besides his effective voice, his composition of speech is simple.
First, he speeches his own life or experience.
and he continues to general ideas or what he wants to say.

c)
I like this presentation, but it seemed that he just read script, he did not use eye contact effectively.
