QUES: In their attempt to ensure white supremacy decades after emancipation, in the early 20th century, most southern states created laws based on the one-drop rule, defining as black, persons with any known African ancestry. This was a stricter interpretation than what had prevailed in the 19th century; it ignored the many mixed families in the state and went against commonly accepted social rules of judging a person by appearance and association. Some courts called it "the traceable amount rule." Anthropologists called it an example of a hypodescent rule, meaning that racially mixed persons were assigned the status of the socially subordinate group.

What did some courts call the one-drop rule?
What is the answer?
ANS: "the traceable amount rule."

In accordance with tradition, they sign by placing the title "Cardinal" (abbreviated Card.) after their personal name and before their surname as, for instance, "John Card(inal) Doe" or, in Latin, "Ioannes Card(inalis) Cognomen". Some writers, such as James-Charles Noonan, hold that, in the case of cardinals, the form used for signatures should be used also when referring to them in English. Official sources such as the Archdiocese of Milwaukee and Catholic News Service say that the correct form for referring to a cardinal in English is normally as "Cardinal [First name] [Surname]". This is the rule given also in stylebooks not associated with the Catholic Church. This style is also generally followed on the websites of the Holy See and episcopal conferences. Oriental Patriarchs who are created Cardinals customarily use "Sanctae Ecclesiae Cardinalis" as their full title, probably because they do not belong to the Roman clergy.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What style is generally not followed on the websites of the Holy See and episcopal conferences?

Question: Some rock formations in the path of a glacier are sculpted into small hills called roche moutonnee, or "sheepback" rock. Roche moutonnee are elongated, rounded, and asymmetrical bedrock knobs that can be produced by glacier erosion. They range in length from less than a meter to several hundred meters long. Roche moutonnee have a gentle slope on their up-glacier sides and a steep to vertical face on their down-glacier sides. The glacier abrades the smooth slope on the upstream side as it flows along, but tears loose and carries away rock from the downstream side via plucking.
Try to answer this question if possible: What is smooth on the downstream side?
Answer: unanswerable

Every Tuesday for four and a half years from September 1940, the two men met privately for lunch to discuss the war in secret and with frankness.
