What does shaw seem to be saying in higgins's quotation below?
"well, sir, in three months i could pass that girl off as a duchess at an ambassador's garden party. i could even get her a place as lady's maid or shop assistant, which requires better english."
lady's maids speak better english than duchesses.
people in upper class social orders have worse english than those who are members of the lower class.
people are more forgiving of errors in english if the person is in a high social class.

oxygen is the first element in group 16 (via) of the periodic table. the periodic table is a chart that shows how chemical elements are related to each other. the elements in group 16 are said to belong to the chalcogen family. other elements in this group include  sulfur, selenium, tellurium,  and  polonium.  the name chalcogen comes from the greek word  chalkos,  meaning "ore." the first two members of the family, oxygen and sulfur, are found in most ores.
