New York grew in importance as a trading port while under British rule in the early 1700s. It also became a center of slavery, with 42% of households holding slaves by 1730, more than any other city other than Charleston, South Carolina. Most slaveholders held a few or several domestic slaves, but others hired them out to work at labor. Slavery became integrally tied to New York's economy through the labor of slaves throughout the port, and the banks and shipping tied to the South. Discovery of the African Burying Ground in the 1990s, during construction of a new federal courthouse near Foley Square, revealed that tens of thousands of Africans had been buried in the area in the colonial years.
What was being built that resulted in the discovery of the African Burial Ground?
A: courthouse

Written Japanese also includes a pair of syllabaries known as kana, derived by simplifying Chinese characters selected to represent syllables of Japanese. The syllabaries differ because they sometimes selected different characters for a syllable, and because they used different strategies to reduce these characters for easy writing: the angular katakana were obtained by selecting a part of each character, while hiragana were derived from the cursive forms of whole characters. Modern Japanese writing uses a composite system, using kanji for word stems, hiragana for inflexional endings and grammatical words, and katakana to transcribe non-Chinese loanwords as well as serve as a method to emphasize native words (similar to how italics are used in Romance languages).
Why do the syllabaries differ?
A: they sometimes selected different characters for a syllable

If all three parameters are used, they are specified in the following form: [frame size][scanning system][frame or field rate] or [frame size]/[frame or field rate][scanning system].[citation needed] Often, frame size or frame rate can be dropped if its value is implied from context. In this case, the remaining numeric parameter is specified first, followed by the scanning system.
When can the frame size or frame rate parameter specification be not dropped?
