Explanation:

For the first question, the Latin root -plac- means "to please" or "to soothe". The prefix im - means "not". So, implacable means "not able to be soothed or pleased".
For the second question, since -plac - relates to calmness and peace (as in being soothed or in a state of tranquility), a placid person would be calm. Midori being calm and smiling fits this as the other options (witty/sarcastic, curt/abrupt, active/busy) do not relate to the root meaning of -plac -.

Answer:

For the first question: unable to be calmed or pleased
For the second question: Midori is always calm and smiling.
