To determine how the diagram helps the reader understand the passage, you would need to consider the content of the passage and the specific details included in the diagram. Here’s a brief analysis of each option:
A. If the diagram shows the growth stages of a peach tree, including its various forms and how it changes over time, then this option is likely correct.
B. If the diagram discusses multiple kinds of plants beyond just peach trees, then this option would be appropriate. However, if it focuses only on peach trees, it wouldn't be the best choice.
C. If the diagram provides step-by-step instructions on how to plant and care for a peach tree, this option would make sense.
D. If the diagram illustrates the process of how plants absorb nutrients and photosynthesize, then this would be a suitable choice.
Given this framework, choose the option that best aligns with what the diagram portrays in relation to the passage.
