Here is a reading on sulfa drugs and World War II along with its accompanying vocabulary-building and comprehension worksheet.
While this material probably qualifies as minutia in the grand sweep of the history of World War II, it is in fact an important moment in the war. This reading is an exposition of cause and effect: by mass chemoprophylaxis (the act of administering medication in the hopes of preventing disease spread) with sulfa drugs, the US Navy saved an estimated 1 million man days and between $50 million and $100 million in 1944 dollars. Ultimately, penicillin replaced sulfadiazine, or sulfa drugs. It is just this kind of cause-and-effect scenario, in my observation in New York State, that tends to inform questions on high-stakes social studies tests.
