Final answer:
The German march across Asia Minor towards Konya was challenged by harsh winter weather, rough terrain, and severe shortages in provisions and supplies. The correct options are A and B.
Step-by-step explanation:
The march for the Germans across Asia Minor towards Konya was a challenge due to the harsh winter conditions, difficult terrain, lack of provisions, and insufficient supplies.
Harsh winter conditions resulted in deep snow and temperatures plummeting below zero, leading to tens of thousands of casualties due to the inability to continue with inadequate supplies.
In addition, the rough terrain further complicated the logistics of supply delivery, and the armies had to contend with difficult terrain and the scarcity of resources like clean water and grass for the horses, exacerbating the lack of provisions.
These combined difficulties made the march extraordinarily challenging. The correct options are A and B.
