Martin moved to a new house. He tracked his electricity consumption over a period of 12 months. Consider the graph which shows the relationship between his monthly electricity consumption and the time.

Which statement best interprets information provided by the graph?
A.
Martin's electricity consumption remained constant for a period.
B.
Martin's electricity consumption kept increasing at the same rate throughout the period.
C.
Martin's electricity consumption kept increasing continuously throughout the period.
D.
Martin's electricity consumption increased for some time and decreased for some time.

To accurately interpret information from the graph, we would need to examine its trends. However, since we cannot view the graph directly, we can infer from the statements:

  • A suggests that there was a period with no change in consumption.
  • B indicates a steady rate of increase throughout the entire period.
  • C implies a continuous increase without any decrease.
  • D indicates fluctuations, where consumption increased at times and decreased at others.

Given the nature of electricity consumption data, it's common for there to be variations due to seasonal factors or changes in usage patterns. Therefore, without the graph, the most sensible interpretation that indicates fluctuations is likely:

D. Martin's electricity consumption increased for some time and decreased for some time.

If you can provide a description of the graph or its key features, I could assist further in confirming the best interpretation.
