Input: Read this: Knots do not necessarily influence the stiffness of structural timber, this will depend on the size and location. Stiffness and elastic strength are more dependent upon the sound wood than upon localized defects. The breaking strength is very susceptible to defects. Sound knots do not weaken wood when subject to compression parallel to the grain.
Question: Depending on the placement and size of a knot, what property of structural timber can be affected?

Output: stiffness

QUES: By that time, the majority of black people in the United States were native-born, so the use of the term "African" became problematic. Though initially a source of pride, many blacks feared that the use of African as an identity would be a hindrance to their fight for full citizenship in the US. They also felt that it would give ammunition to those who were advocating repatriating black people back to Africa. In 1835, black leaders called upon Black Americans to remove the title of "African" from their institutions and replace it with "Negro" or "Colored American". A few institutions chose to keep their historic names, such as the African Methodist Episcopal Church. African Americans popularly used the terms "Negro" or "colored" for themselves until the late 1960s.

What terms did African Americans use instead?
What is the answer?
ANS: "Negro" or "colored"

Before glaciation, mountain valleys have a characteristic "V" shape, produced by eroding water. During glaciation, these valleys are widened, deepened, and smoothed, forming a "U"-shaped glacial valley. The erosion that creates glacial valleys eliminates the spurs of earth that extend across mountain valleys, creating triangular cliffs called truncated spurs. Within glacial valleys, depressions created by plucking and abrasion can be filled by lakes, called paternoster lakes. If a glacial valley runs into a large body of water, it forms a fjord.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What shape do mountain valleys have pre-glacation?
Ah, so.. characteristic "V" shape

QUES: By 1840, the Market Hall and Sheds, where fresh meat and produce were brought daily, became a hub of commercial activity. The slave trade also depended on the port of Charleston, where ships could be unloaded and the slaves bought and sold. The legal importation of African slaves had ended in 1808, although smuggling was significant. However, the domestic trade was booming. More than one million slaves were transported from the Upper South to the Deep South in the antebellum years, as cotton plantations were widely developed through what became known as the Black Belt. Many slaves were transported in the coastwise slave trade, with slave ships stopping at ports such as Charleston.
What industry never depended on the port of Charleston?
