‘In urbem’ would make more sense. ‘Ad urbem’ means that he won’t enter the city.
What about a different word order; when is it arbitrary and when is it not, are the adjectives after the nouns, what about the verbs and accusative? I did it like this: Marcus facit iter longum ad urbem.
The others word order are okay, I think as long as you keep "ad urbem" together. So, report them.
I am writing the correct answer and it is not accepting it
I wrote "Marcus iter facit ad urbem longum" but was marked wrong. Is that me getting it wrong or the computer?
I'm merely a beginner but doesn't the adjective (longum) have to be next to the noun (iter) thus - Marcus iter longum facit ad urbem. I'll have a go at using this next time to check.
Yes, seems to be OK that way
