Alright, adventurers of the academic realm, let's tackle these questions, one witty remark at a time:

5. Having made his first film earlier this year, he is ___ starring in a new musical.

• The correct choice is B. currently. Why? Because he's presently (like, right now) working on those jazz hands in a musical.

6. Many a person ___ it unacceptable for factories to emit hazardous gases.

• The correct choice is A. finds. This one is a classic case of "it sounds like many, but it's actually 'a person' finding something." Just trust the grammar magic!

7. Today marks __ day of the week, with the temperature at 42°C in midday.

• The correct choice is A. the hottest. Because at 42°C, it's hotter than a jalapeño eating contest!

8. The forest fire __ thick black smoke, polluting the whole city.

• The correct choice is D. gave off. Much like giving off bad vibes, but more environmentally concerning.

9. Lynn: “The forecast says it will rain heavily this afternoon.”
   Katie: “___”

• The correct choice is C. I’d better bring an umbrella. Naturally, because getting soaked might ruin the afternoon picnic you’re pretending not to have.
