Scales can represent a. a range of information c. proportional measurement b. a range of resources d. all of the above

All of the above because of the variety of things it can show

"D all of the above" Is the answer you are looking for. Because these are all that a scale could be. It could measure a range of information, measurement of proportion and a measurement of resources. 
Hope this helps!

Idon’t know can you give me background information
