Death of a Naturalist: What event marks a shift from fascination to fear?

• A. Then one hot day angry frogs invaded the flax-dam
• B. The teacher's lesson ends
• C. The ponds become still
• D. The birds fly away

Answer: (A)

The shift from fascination to fear happens at the moment the speaker encounters the invading frogs on a hot day. Before this, nature is a source of endless wonder, but the line about “one hot day” with “angry frogs” invading the flax-dam introduces danger and disruption. The word “invaded” makes nature feel aggressive rather than beautiful, darkening the tone and signaling the loss of the child’s innocent curiosity. This single event marks the turning point the poem builds toward, showing how the speaker’s view of the natural world moves from admiration to threat. The other options don’t describe a moment that changes the mood in this way.
