PROBLEM: Conversely, some Slavs were assimilated into other populations. Although the majority continued south, attracted by the riches of the territory which would become Bulgaria, a few remained in the Carpathian basin and were ultimately assimilated into the Magyar or Romanian population. There is a large number of river names and other placenames of Slavic origin in Romania.[better source needed]

SOLUTION: Slavs that remained in the Carpathian basin were assimilated into who?

PROBLEM: Rome had no separate priestly caste or class. The highest authority within a community usually sponsored its cults and sacrifices, officiated as its priest and promoted its assistants and acolytes. Specialists from the religious colleges and professionals such as haruspices and oracles were available for consultation. In household cult, the paterfamilias functioned as priest, and members of his familia as acolytes and assistants. Public cults required greater knowledge and expertise. The earliest public priesthoods were probably the flamines (the singular is flamen), attributed to king Numa: the major flamines, dedicated to Jupiter, Mars and Quirinus, were traditionally drawn from patrician families. Twelve lesser flamines were each dedicated to a single deity, whose archaic nature is indicated by the relative obscurity of some. Flamines were constrained by the requirements of ritual purity; Jupiter's flamen in particular had virtually no simultaneous capacity for a political or military career.

SOLUTION: What was lacking as to the profession of a priest class in Rome?

PROBLEM: Ultimately, Lee spent over two and a half years writing To Kill a Mockingbird. The book was published on July 11, 1960. After rejecting the "Watchman" title, it was initially re-titled Atticus, but Lee renamed it "To Kill a Mockingbird" to reflect that the story went beyond just a character portrait. The editorial team at Lippincott warned Lee that she would probably sell only several thousand copies. In 1964, Lee recalled her hopes for the book when she said, "I never expected any sort of success with 'Mockingbird.' ... I was hoping for a quick and merciful death at the hands of the reviewers but, at the same time, I sort of hoped someone would like it enough to give me encouragement. Public encouragement. I hoped for a little, as I said, but I got rather a whole lot, and in some ways this was just about as frightening as the quick, merciful death I'd expected." Instead of a "quick and merciful death", Reader's Digest Condensed Books chose the book for reprinting in part, which gave it a wide readership immediately. Since the original publication, the book has never been out of print.

SOLUTION:
What date did To Kill a Mockingbird begin to circulate?
