Passage Summary: People who work outside the home spend much less time cooking dinner than those who stay home, yet both groups eat meals that are equally healthy and fancy.

Reasoning: Adults working outside the home spend 100 minutes less on dinner prep than those who do not, yet the meals of both groups are identical in quality and variety.

Analysis: The mystery here is how the working group achieves the same meal quality in significantly less time. We need a factor that explains this efficiency or offsets the time difference. Perhaps they use time-saving appliances, buy pre-chopped ingredients, or maybe the non-working group just spends more time on fluff tasks that don't improve the meal's stats. Look for an explanation that bridges the gap between less time spent and equal meal quality.
