Match the periods with the characteristics of minutes and gigabytes consumed.

Solution:

To solve this, we need to analyze the graph and compare the values of minutes (solid line) and gigabytes (dashed line) for the given periods.

• A) January-February: In January, minutes were around 250 and gigabytes around 1. In February, minutes decreased to about 150, and gigabytes also decreased to about 0.5. Thus, both minutes and gigabytes decreased. This matches characteristic 1) расход минут уменьшился и расход гигабайтов уменьшился.
• Б) April-May: In April, minutes were around 300 and gigabytes around 2. In May, minutes increased to about 350, and gigabytes also increased to about 3. Thus, both minutes and gigabytes increased. This matches characteristic 2) расход минут увеличился и расход гигабайтов увеличился.
• В) June-July: In June, minutes were around 300 and gigabytes around 3. In July, minutes decreased to about 200, while gigabytes increased to about 3.5. Thus, minutes decreased and gigabytes increased. This matches characteristic 3) расход гигабайтов увеличился, а расход минут уменьшился.
• Г) July-August: In July, minutes were around 200 and gigabytes around 3.5. In August, minutes increased to about 350, and gigabytes decreased to about 2. Thus, minutes increased and gigabytes decreased. This matches characteristic 4) расход минут увеличился, а расход гигабайтов уменьшился.
