Which scenario could indicate that the couple shares responsibilities in cooking?

The scenario indicating that the couple shares responsibilities in cooking is the last time each spouse cooked. This option reflects an active contribution to the cooking responsibilities, as it directly addresses who has recently taken the initiative to prepare meals. If both spouses can recall the last time they each cooked, it suggests a shared engagement in the cooking process, showcasing a balance in responsibilities rather than one partner carrying the entire burden.

In contrast, how often they eat out only provides information about their dining habits and does not reveal anything about their cooking responsibilities at home. Knowing how many recipes they each know does not necessarily translate to who is actually taking part in cooking, as one partner may have extensive knowledge yet may not be the one who cooks regularly. Additionally, while grocery shopping is related to meal preparation, it does not directly reflect the act of cooking itself, as one partner may do the shopping but not participate in cooking the meals.
