Fill in with suitable conjunction: He advanced ______ he could.
- a.until
- b.while
- c.as far as
- d.as
Answer: (C) as far as
"As far as he could" is the idiomatic way to express reaching the maximum possible extent or limit of an action, which fits the sense of the sentence; "until", "while" and plain "as" don't convey this limiting sense.
