Many kitchen tools today are made with easy-to-grip silicone handles, which are a vast improvement over old wire tools that were often painful to use. although the advantages of silicone over wire might seem obvious, kitchenware makers were unaware of the problems with wire tools until they hired ethnographers. ethnographers visited people at home, observed how they worked in the kitchen, and were able to determine what sorts of things could be sold to them. this ethnography is an example of:

all cities are in states or provnies then country

all cities have people

some are rich

some are poor

some are average
