Question

kitchens in the 1990s were more likely to open into common areas or include some additional functional family space. what was the main driver behind this change?
there was a higher value placed on entertaining.
people were cooking more often.
many women entered the workforce.
families became larger.

Explanation:

In the 1990s, social trends emphasized entertaining guests. Open - concept kitchens that connected to common areas facilitated hosting and socializing. Cooking frequency (people cooking more often) doesn't directly relate to kitchen layout opening into common areas. Women entering the workforce might affect time for cooking but not the layout for common areas. Families becoming larger would likely lead to more private spaces rather than open - concept ones for common areas.

Answer:

There was a higher value placed on entertaining.
