Article: The 1775 treatise "The Natural Varieties of Mankind", by Johann Friedrich Blumenbach proposed five major divisions: the Caucasoid race, Mongoloid race, Ethiopian race (later termed Negroid, and not to be confused with the narrower Ethiopid race), American Indian race, and Malayan race, but he did not propose any hierarchy among the races. Blumenbach also noted the graded transition in appearances from one group to adjacent groups and suggested that "one variety of mankind does so sensibly pass into the other, that you cannot mark out the limits between them".

Question: What year was Blumenbach's treatise published?
Ans: 1775


Here is a question about this article: Paul's Christology has a specific focus on the death and resurrection of Jesus. For Paul, the crucifixion of Jesus is directly related to his resurrection and the term "the cross of Christ" used in Galatians 6:12 may be viewed as his abbreviation of the message of the gospels. For Paul, the crucifixion of Jesus was not an isolated event in history, but a cosmic event with significant eschatological consequences, as in 1 Corinthians 2:8. In the Pauline view, Jesus, obedient to the point of death (Philippians 2:8) died "at the right time" (Romans 4:25) based on the plan of God. For Paul the "power of the cross" is not separable from the Resurrection of Jesus.
What is the answer to this question: Paul claims the Resurrection was needed for what reason?
****
So... based on the plan of God


The problem: Answer a question about this article:
Motors have very little room for electrical insulation so they generally have low voltage ratings. Because transformers (prior to the development of power electronics) cannot step down DC voltages, trains were supplied with a relatively low DC voltage that the motors can use directly. The most common DC voltages are listed in the previous section. Third (and fourth) rail systems almost always use voltages below 1 kV for safety reasons while overhead wires usually use higher voltages for efficiency. ("Low" voltage is relative; even 600 V can be instantly lethal when touched.)
Which system uses higher voltages?
****
The answer: overhead wires


Problem: Please answer a question about the following article about Electric motor:
Large brushes are desired for a larger brush contact area to maximize motor output, but small brushes are desired for low mass to maximize the speed at which the motor can run without the brushes excessively bouncing and sparking. (Small brushes are also desirable for lower cost.) Stiffer brush springs can also be used to make brushes of a given mass work at a higher speed, but at the cost of greater friction losses (lower efficiency) and accelerated brush and commutator wear. Therefore, DC motor brush design entails a trade-off between output power, speed, and efficiency/wear.
What type of brushes are cheapest?
A: small


Question: Read this and answer the question

The Germans expected to negotiate an end to the war but immediately ordered an advance on Paris; by 15 September Moltke issued the orders for an investment of Paris and on 20 September the encirclement was complete. Bismarck met Favre on 18 September at the Château de Ferrières and demanded a frontier immune to a French war of revenge, which included Strasbourg, Alsace and most the Moselle department in Lorraine of which Metz was the capital. In return for an armistice for the French to elect a National Assembly, Bismarck demanded the surrender of Strasbourg and the fortress city of Toul. To allow supplies into Paris, one of the perimeter forts had to be handed over. Favre was unaware that the real aim of Bismarck in making such extortionate demands was to establish a durable peace on the new western frontier of Germany, preferably by a peace with a friendly government, on terms acceptable to French public opinion. An impregnable military frontier was an inferior alternative to him, favoured only by the militant nationalists on the German side.

Bismarck demanded the surrender of Strasbourg and what fortress city?
Answer: Toul


Proponents of affirmative action recognize that the policy is inherently unequal; however, minding the inescapable fact that historic inequalities exist in America, they believe the policy is much more fair than one in which these circumstances are not taken into account. Furthermore, those in favor of affirmative action see it as an effort towards inclusion rather than a discriminatory practice. "Job discrimination is grounded in prejudice and exclusion, whereas affirmative action is an effort to overcome prejudicial treatment through inclusion. The most effective way to cure society of exclusionary practices is to make special efforts at inclusion, which is exactly what affirmative action does."
What does affirmative action supposedly aim to do?
overcome prejudicial treatment through inclusion
