Problem: Multiracial American:

Anti-miscegenation laws were passed in most states during the 18th, 19th and early 20th centuries, but this did not prevent white slaveholders, their sons, or other powerful white men from taking slave women as concubines and having multiracial children with them. In California and the western US, there were greater numbers of Latino and Asian residents. These were prohibited from official relationships with whites. White legislators passed laws prohibiting marriage between European and Asian Americans until the 1950s.

Who was permitted to have official relationships with whites?

A: unanswerable

Problem: If there are differences within a growth ring, then the part of a growth ring nearest the center of the tree, and formed early in the growing season when growth is rapid, is usually composed of wider elements. It is usually lighter in color than that near the outer portion of the ring, and is known as earlywood or springwood. The outer portion formed later in the season is then known as the latewood or summerwood. However, there are major differences, depending on the kind of wood (see below).
Is earlywood usually lighter or darker than the part of the growth ring that forms later in the season?

Answer: lighter

In 1260, control passed to the Mamluk sultans of Egypt. The country was located between the two centres of Mamluk power, Cairo and Damascus, and only saw some development along the postal road connecting the two cities. Jerusalem, although left without the protection of any city walls since 1219, also saw a flurry of new construction projects centred around the Al-Aqsa Mosque compound (the Temple Mount). In 1266 the Mamluk Sultan Baybars converted the Cave of the Patriarchs in Hebron into an exclusive Islamic sanctuary and banned Christians and Jews from entering, which previously would be able to enter it for a fee. The ban remained in place until Israel took control of the building in 1967.
When was control passed to the Mamluk sultans of Egypt?
A: 1260

Context and question: While textual criticism developed into a discipline of thorough analysis of the Bible both the Hebrew Bible and the New Testament scholars also use it to determine the original content of classic texts, such as Plato's Republic. There are far fewer witnesses to classical texts than to the Bible, so scholars can use stemmatics and, in some cases, copy text editing. However, unlike the New Testament where the earliest witnesses are within 200 years of the original, the earliest existing manuscripts of most classical texts were written about a millennium after their composition. All things being equal, textual scholars expect that a larger time gap between an original and a manuscript means more changes in the text.
What's the gap between original classical texts and subsequent editions of the same works?
Answer: about a millennium after their composition

Question: Nintendo's near monopoly on the home video game market left it with a degree of influence over the industry. Unlike Atari, which never actively courted third-party developers (and even went to court in an attempt to force Activision to cease production of Atari 2600 games), Nintendo had anticipated and encouraged the involvement of third-party software developers; strictly, however, on Nintendo's terms. Some of the Nintendo platform-control measures were adopted by later console manufacturers such as Sega, Sony, and Microsoft, although not as stringent.
Is there an answer to this question: Nintendo actively encouraged the involvement of what?

Answer: third-party software developers

Southampton Water has the benefit of a double high tide, with two high tide peaks, making the movement of large ships easier. This is not caused as popularly supposed by the presence of the Isle of Wight, but is a function of the shape and depth of the English Channel. In this area the general water flow is distorted by more local conditions reaching across to France.
In addition to its shape, what property of the English Channel affects water flow in Southampton Water?
A:
depth
