How do the girls stand out as Americans while in the Motherland?

There are several ways that the girls stand out as Americans. First, many struggle with their native tongue and resort to speaking English. Second, they are taller and fuller due to their American diets than their relatives in the Motherland. Third, they get sick from the local water. Fourth, they easily get lost. Fifth, they do not dress appropriately, and their immodest clothing stand out against the modest dress of the locals.
