Problem: Race and ethnicity in the United States Census:

President Franklin D. Roosevelt promoted a "good neighbor" policy that sought better relations with Mexico. In 1935 a federal judge ruled that three Mexican immigrants were ineligible for citizenship because they were not white, as required by federal law. Mexico protested, and Roosevelt decided to circumvent the decision and make sure the federal government treated Hispanics as white. The State Department, the Census Bureau, the Labor Department, and other government agencies therefore made sure to uniformly classify people of Mexican descent as white. This policy encouraged the League of United Latin American Citizens in its quest to minimize discrimination by asserting their whiteness.

In what year did a federal judge say that three immigrants from Mexico were not eligible to be citizens because of their race?

A: 1935

Problem: Capacitor:

Charles Pollak (born Karol Pollak), the inventor of the first electrolytic capacitors, found out that the oxide layer on an aluminum anode remained stable in a neutral or alkaline electrolyte, even when the power was switched off. In 1896 he filed a patent for an "Electric liquid capacitor with aluminum electrodes." Solid electrolyte tantalum capacitors were invented by Bell Laboratories in the early 1950s as a miniaturized and more reliable low-voltage support capacitor to complement their newly invented transistor.

Who invented the first electrolytic capacitor?

A: Charles Pollak

Problem: New Haven, Connecticut:

However, an analysis by the Regional Data Cooperative for Greater New Haven, Inc., has shown that due to issues of comparative denominators and other factors, such municipality-based rankings can be considered inaccurate. For example, two cities of identical population can cover widely differing land areas, making such analyses irrelevant. The research organization called for comparisons based on neighborhoods, blocks, or standard methodologies (similar to those used by Brookings, DiversityData, and other established institutions), not based on municipalities.

Analysis by what organization detailed that municipality-based rankings may be inaccurate?

A: Regional Data Cooperative for Greater New Haven, Inc

Problem: Napoleon:

Before going to Iberia, Napoleon decided to address several lingering issues with the Russians. At the Congress of Erfurt in October 1808, Napoleon hoped to keep Russia on his side during the upcoming struggle in Spain and during any potential conflict against Austria. The two sides reached an agreement, the Erfurt Convention, that called upon Britain to cease its war against France, that recognized the Russian conquest of Finland from Sweden, and that affirmed Russian support for France in a possible war against Austria "to the best of its ability." Napoleon then returned to France and prepared for war. The Grande Armee, under the Emperor's personal command, rapidly crossed the Ebro River in November 1808 and inflicted a series of crushing defeats against the Spanish forces. After clearing the last Spanish force guarding the capital at Somosierra, Napoleon entered Madrid on 4 December with 80,000 troops. He then unleashed his soldiers against Moore and the British forces. The British were swiftly driven to the coast, and they withdrew from Spain entirely after a last stand at the Battle of Corunna in January 1809.

The Erfurt Convention recognized the Russian takeover of which formerly Swedish possession?
---
A:
Finland
