Analyze the illustration's overall structure

Using the Visual Text Integration knowledge point, we examine the diagram from left to right. It begins with extraction sources ("oil and gas well", "gas well"), moves through processing stages ("separation", "gas processing plant", "compressor station", "odorant"), and ends with storage and delivery to "consumers". This sequential flow represents a complete supply chain.

Evaluate the multiple-choice options

Using the Reading Comprehension knowledge point, we compare the options against the diagram's scope:

• "the differences between gas wells and oil wells": This is a minor detail at the start, not the main message.
• "the separation process of oil and water": This is only one early step in the system.
• "the process of producing and distributing natural gas": This matches the entire sequence from extraction to consumer delivery.
• "the specifications of natural gas storage reservoirs": This refers only to a single storage component in the middle.
