Problem: Szlachta:

The first "free election" (Polish: "wolna elekcja") of a king took place in 1492. (To be sure, some earlier Polish kings had been elected with help from bodies such as that which put Casimir II on the throne, thereby setting a precedent for free elections.) Only senators voted in the 1492 free election, which was won by John I Albert. For the duration of the Jagiellonian Dynasty, only members of that royal family were considered for election; later, there would be no restrictions on the choice of candidates.

What dynasty was in reign during the election of 1492?
---
A: Jagiellonian Dynasty


Problem: The TSFSR existed from 1922 to 1936, when it was divided up into three separate entities (Armenian SSR, Azerbaijan SSR, and Georgian SSR). Armenians enjoyed a period of relative stability under Soviet rule. They received medicine, food, and other provisions from Moscow, and communist rule proved to be a soothing balm in contrast to the turbulent final years of the Ottoman Empire. The situation was difficult for the church, which struggled under Soviet rule. After the death of Vladimir Lenin, Joseph Stalin took the reins of power and began an era of renewed fear and terror for Armenians.
Which three parts make up the TSFSR?
---
Answer: Armenian SSR, Azerbaijan SSR, and Georgian SSR

Context and question: In a time when royals were expected to marry fellow royals, it was unusual that Albert had a great deal of freedom in choosing a prospective wife. An infatuation with the already-married Australian socialite Sheila, Lady Loughborough, came to an end in April 1920 when the King, with the promise of the dukedom of York, persuaded Albert to stop seeing her. That year, he met for the first time since childhood Lady Elizabeth Bowes-Lyon, the youngest daughter of the Earl and Countess of Strathmore and Kinghorne. He became determined to marry her. She rejected his proposal twice, in 1921 and 1922, reportedly because she was reluctant to make the sacrifices necessary to become a member of the royal family. In the words of Lady Elizabeth's mother, Albert would be "made or marred" by his choice of wife. After a protracted courtship, Elizabeth agreed to marry him.
In what year did Albert first meet Lady Elizabeth?
Answer: unanswerable


Question: Tajikistan's rivers, such as the Vakhsh and the Panj, have great hydropower potential, and the government has focused on attracting investment for projects for internal use and electricity exports. Tajikistan is home to the Nurek Dam, the highest dam in the world. Lately, Russia's RAO UES energy giant has been working on the Sangtuda-1 hydroelectric power station (670 MW capacity) commenced operations on 18 January 2008. Other projects at the development stage include Sangtuda-2 by Iran, Zerafshan by the Chinese company SinoHydro, and the Rogun power plant that, at a projected height of 335 metres (1,099 ft), would supersede the Nurek Dam as highest in the world if it is brought to completion. A planned project, CASA 1000, will transmit 1000 MW of surplus electricity from Tajikistan to Pakistan with power transit through Afghanistan. The total length of transmission line is 750 km while the project is planned to be on Public-Private Partnership basis with the support of WB, IFC, ADB and IDB. The project cost is estimated to be around US$865 million. Other energy resources include sizable coal deposits and smaller reserves of natural gas and petroleum.
Is there an answer to this question: What is something that the rivers in Tajikistan are good for?

Answer: hydropower potential


Although the atomic structure of glass shares characteristics of the structure in a supercooled liquid, glass tends to behave as a solid below its glass transition temperature. A supercooled liquid behaves as a liquid, but it is below the freezing point of the material, and in some cases will crystallize almost instantly if a crystal is added as a core. The change in heat capacity at a glass transition and a melting transition of comparable materials are typically of the same order of magnitude, indicating that the change in active degrees of freedom is comparable as well. Both in a glass and in a crystal it is mostly only the vibrational degrees of freedom that remain active, whereas rotational and translational motion is arrested. This helps to explain why both crystalline and non-crystalline solids exhibit rigidity on most experimental time scales.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Atomically, glass is similar to what?
Ah, so..
a supercooled liquid
