To determine which response best aligns with the first subheading's intent and how it relates to the title, we should consider what the title communicates. The title states that "Butterflies are disappearing in Ohio" and suggests a broader implication for insect populations everywhere.
Among the provided response options, the most suitable one appears to be:
"It signals that the section will tell that scientists discovered that butterflies were disappearing in Ohio and why it matters."
This option encapsulates both the discovery of the butterfly population decline and hints at broader ecological implications, which directly relates to the title and its concerns about the larger context of insect populations.
