These are just my interpretations.Dear teachers,
I have four questions:
At last she managed to get the fire lit.
This is the same structure as "to get the car started" . Is that right? And since you explained that I can also say "to get the car to start" does it mean I can also say "to get the fire to light"?
Yes. I think it's probably best to think of this use as the causative get.

Beyond determination, courage, and vision, I look for students with a growing sense of confidence. For Iknow from experience that confidence is ______ necessary credential that __________ college students must take away with them.
a. the one, all b. the, many c. one, all
The key is "a". Could you please kindly explain why 'b' and 'c' are wrong?
And what's the difference between "the one" and "one"?
It seems to me that C is perhaps possible, but the text is singling out a particular credential and the definate article serves to emphasize this.
The streets had been _____ before the parade begun.
a. swept clean b. swept cleanly
The key is 'a'. No problem. 'b' is not correct because cleanly doesn't mean ''without dust'. Is that right?
Swept cleanly sounds very strange. How would you even sweep cleanly?
Swept clean makes more sense. It describes the street (as being clean) rather than describing the actual manner of sweeping (which doesn't, to me, make sense).
Professor Yuan is reported ______ another breakthrough in his research.
a. to have made b. having made
The key is 'a' which means he has already made the breakthrough. My question is why 'b' isn't correct which also means something has taken place?
Having + past participle acts as a perfect tense.
Having worked there for 6 years, I decided to quit.
I had worked there for six years when I decided to quit.
This sentence requires a simple past tense to describe something which happened at a specific point in the past.
Professor Yuan made a breakthrough.
Looking forward to hearing from you.
Thank you in advance.
