I drew a map of Iran without looking at it. Then I checked my drawing with the real map, and made this statement:
I knew there is a slope in the western borders but I didn’t know the details. For the eastern border, I should have pulled it more toward south-east. Mine is very straight.
- is it south-east or the south-east? I think since the directions are a limited and specific set, it needs "the".
- should I use "border" or "borders" in the first or second case?
