ANSWER:

The concern of geography with space puts 'Scale' at the 'center of its agenda'.

EXPLANATION:

The scale on a map is the 'ratio of distance' on a map to the 'corresponding actual map'. Scale is helpful for measurement, research and study and navigation of different places on earth. The accuracy of a geographical research report is proportional to the 'accuracy of the scale used'. For these reasons we can conclude scale as the center of agenda in geography with space.
