The problem: Answer a question about this article:
As the universe evolves in time, more and more of its energy becomes trapped in irreversible states (i.e., as heat or other kinds of increases in disorder). This has been referred to as the inevitable thermodynamic heat death of the universe. In this heat death the energy of the universe does not change, but the fraction of energy which is available to do work through a heat engine, or be transformed to other usable forms of energy (through the use of generators attached to heat engines), grows less and less.
In this heat death of energy, what does not change?
****
The answer: energy of the universe


Problem: Please answer a question about the following article about Royal assent:
Originally, legislative power was exercised by the sovereign acting on the advice of the Curia Regis, or Royal Council, in which important magnates and clerics participated and which evolved into parliament. The so-called Model Parliament included bishops, abbots, earls, barons, and two knights from each shire and two burgesses from each borough among its members. In 1265, the Earl of Leicester irregularly called a full parliament without royal authorisation. The body eventually came to be divided into two branches: bishops, abbots, earls, and barons formed the House of Lords, while the shire and borough representatives formed the House of Commons. The King would seek the advice and consent of both houses before making any law. During Henry VI's reign, it became regular practice for the two houses to originate legislation in the form of bills, which would not become law unless the sovereign's assent was obtained, as the sovereign was, and still remains, the enactor of laws. Hence, all acts include the clause "Be it enacted by the Queen's (King's) most Excellent Majesty, by and with the advice and consent of the Lords Spiritual and Temporal, and Commons, in this present Parliament assembled, and by the authority of the same, as follows...". The Parliament Acts 1911 and 1949 provide a second potential preamble if the House of Lords were to be excluded from the process.
Which body did the shire and borough representatives form?
A: House of Commons

In chemical terms, the difference between hardwood and softwood is reflected in the composition of the constituent lignin. Hardwood lignin is primarily derived from sinapyl alcohol and coniferyl alcohol. Softwood lignin is mainly derived from coniferyl alcohol.

Which kind of wood contains lignin derived from two main alcohol sources?
Answer: Hardwood


Problem: Other city states formed federated states in self-defense, such as the Aetolian League (est. 370 BCE), the Achaean League (est. 280 BCE), the Boeotian league, the "Northern League" (Byzantium, Chalcedon, Heraclea Pontica and Tium) and the "Nesiotic League" of the Cyclades. These federations involved a central government which controlled foreign policy and military affairs, while leaving most of the local governing to the city states, a system termed sympoliteia. In states such as the Achaean league, this also involved the admission of other ethnic groups into the federation with equal rights, in this case, non-Achaeans. The Achean league was able to drive out the Macedonians from the Peloponnese and free Corinth, which duly joined the league.
Byzantium, Chalcedon, Heraclea Pontica and Tium formed what league?
The answer is the following: Northern League


In some cases this is done in a more extreme manner, not simply to cancel a small amount of residual reactance, but to resonate an antenna whose resonance frequency is quite different from the intended frequency of operation. For instance, a "whip antenna" can be made significantly shorter than 1/4 wavelength long, for practical reasons, and then resonated using a so-called loading coil. This physically large inductor at the base of the antenna has an inductive reactance which is the opposite of the capacitative reactance that such a vertical antenna has at the desired operating frequency. The result is a pure resistance seen at feedpoint of the loading coil; unfortunately that resistance is somewhat lower than would be desired to match commercial coax.[citation needed]
What is the opposite of inductive reactance?
capacitative reactance


Here is a question about this article: Coordination strategies differ when adjacent time zones shift clocks. The European Union shifts all at once, at 01:00 UTC or 02:00 CET or 03:00 EET; for example, Eastern European Time is always one hour ahead of Central European Time. Most of North America shifts at 02:00 local time, so its zones do not shift at the same time; for example, Mountain Time is temporarily (for one hour) zero hours ahead of Pacific Time, instead of one hour ahead, in the autumn and two hours, instead of one, ahead of Pacific Time in the spring. In the past, Australian districts went even further and did not always agree on start and end dates; for example, in 2008 most DST-observing areas shifted clocks forward on October 5 but Western Australia shifted on October 26. In some cases only part of a country shifts; for example, in the US, Hawaii and most of Arizona do not observe DST.
What is the answer to this question: In addition to much of the state of Arizona, what U.S. state does not ever change their clocks for DST?
****
So...
Hawaii
