which factor made it most difficult for soldiers to cross the area between the trenches?\no the land was too wide to be crossed.\no the land was not claimed by either side, so access to it was impossible.\no the land was defended by civilians who prohibited fighting.\no the land was mined territory and was subject to artillery, shelling, and gunfire.
Answer
Brief Explanations:
In trench - warfare, the area between trenches (no - man's land) was mined and under heavy fire from artillery, shelling, and gunfire, making it extremely dangerous and difficult to cross. The other options are incorrect as the land was not too wide to be the main issue, access was not impossible due to lack of claim, and civilians did not defend the area and prohibit fighting.
Answer:
The land was mined territory and was subject to artillery, shelling, and gunfire.
