Explanation:

Step1: Analyze bar - graph heights

By observing the bar - graph, the height of the bar for radio is the shortest among television, telephone, radio, and computer.

Step2: Determine number of radio repairs

The height of the radio bar corresponds to 2 on the vertical axis, so the number of radio repairs is 2.

Step3: Find number of telephone and radio repairs

The number of telephone repairs is 12 (height of the telephone bar) and the number of radio repairs is 2.

Step4: Calculate the difference

To find how many more telephones than radios were repaired, we subtract the number of radio repairs from the number of telephone repairs: $12 - 2=10$.

Step5: Check number of repairs for each device

The number of television repairs is 8, telephone repairs is 12, radio repairs is 2, and computer repairs is 10. None of the values is 12 or more.

Answer:

(a) Radio; 2
(b) 10
(c) 0
