JWW EXERCISE 616

I am having problems with q4. The best I can come up with is
. For if once we keep two marches which (are) of three days away, the enemy will no longer follow us
I know this isn’t right because “road/journey” is singular
The solution can’t be “a journey of two or three days” because it doesn’t say " of two"
Where does the two fit in?

Since I can’t find my JWW file, could you write out the original Greek (you can type in polytonic Greek using http://users.ox.ac.uk/~tayl0010/letters_table_caretpos2.htm )

ἦν γὰ? ἆπαξ δύο ἦ τ?ιῶν ἡμε?ῶν ?δὸν ἀπόσχωμεν, ο?κέτι οἱ πολέμιοι ἡμῖν ἕψονται
[I think all the accents are right - JWW is a bit smudged

You have replaced the gravs with circumflexes over the first and 5th word.
~~For if once we keep the march within/of* two** or(á¼¢) three days, the enemy will no longer follow us.

*It depends how you’d like to read the genitive.
**Notice how the dual of duo is “declined” in #757, which is the subject and purpose of this lesson.
