Concept:
• Tone and mood analysis requires matching the vocabulary to the descriptions provided in the text.
• Situations involving child labor, darkness, and health hazards are inherently negative.
Step 1: Review the descriptors used for the hutments
The text uses words like "dark," "flickering oil lamps," and mentions that workers lose their "eyesight" before becoming adults.
Step 2: Evaluate the given bracketed options
"Comfortable" implies ease, health, and well-being, which contradicts every detail in the extract.
"Pathetic" refers to a condition that is miserably inadequate and heart-breaking.
Step 3: Finalize the selection
Given the tragic health consequences and the gloomy environment, "pathetic" is the only appropriate descriptor.
