Problem: Frederic Chopin:

Chopin's tombstone, featuring the muse of music, Euterpe, weeping over a broken lyre, was designed and sculpted by Clesinger. The expenses of the funeral and monument, amounting to 5,000 francs, were covered by Jane Stirling, who also paid for the return of the composer's sister Ludwika to Warsaw. Ludwika took Chopin's heart in an urn, preserved in alcohol, back to Poland in 1850.[n 9] She also took a collection of two hundred letters from Sand to Chopin; after 1851 these were returned to Sand, who seems to have destroyed them.

How much did Chopin's funeral cost?

A: 5,000 francs

Problem: Although the two displayed great respect and admiration for each other, their friendship was uneasy and had some qualities of a love-hate relationship. Harold C. Schonberg believes that Chopin displayed a "tinge of jealousy and spite" towards Liszt's virtuosity on the piano, and others have also argued that he had become enchanted with Liszt's theatricality, showmanship and success. Liszt was the dedicatee of Chopin's Op. 10 Etudes, and his performance of them prompted the composer to write to Hiller, "I should like to rob him of the way he plays my studies." However, Chopin expressed annoyance in 1843 when Liszt performed one of his nocturnes with the addition of numerous intricate embellishments, at which Chopin remarked that he should play the music as written or not play it at all, forcing an apology. Most biographers of Chopin state that after this the two had little to do with each other, although in his letters dated as late as 1848 he still referred to him as "my friend Liszt". Some commentators point to events in the two men's romantic lives which led to a rift between them; there are claims that Liszt had displayed jealousy of his mistress Marie d'Agoult's obsession with Chopin, while others believe that Chopin had become concerned about Liszt's growing relationship with George Sand.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In the spring of 1834, Chopin attended the Lower Rhenish Music Festival in Aix-la-Chapelle with Hiller, and it was there that Chopin met Felix Mendelssohn. After the festival, the three visited Dusseldorf, where Mendelssohn had been appointed musical director. They spent what Mendelssohn described as "a very agreeable day", playing and discussing music at his piano, and met Friedrich Wilhelm Schadow, director of the Academy of Art, and some of his eminent pupils such as Lessing, Bendemann, Hildebrandt and Sohn. In 1835 Chopin went to Carlsbad, where he spent time with his parents; it was the last time he would see them. On his way back to Paris, he met old friends from Warsaw, the Wodzinskis. He had made the acquaintance of their daughter Maria in Poland five years earlier, when she was eleven. This meeting prompted him to stay for two weeks in Dresden, when he had previously intended to return to Paris via Leipzig. The sixteen-year-old girl's portrait of the composer is considered, along with Delacroix's, as among Chopin's best likenesses. In October he finally reached Leipzig, where he met Schumann, Clara Wieck and Felix Mendelssohn, who organised for him a performance of his own oratorio St. Paul, and who considered him "a perfect musician". In July 1836 Chopin travelled to Marienbad and Dresden to be with the Wodzinski family, and in September he proposed to Maria, whose mother Countess Wodzinska approved in principle. Chopin went on to Leipzig, where he presented Schumann with his G minor Ballade. At the end of 1836 he sent Maria an album in which his sister Ludwika had inscribed seven of his songs, and his 1835 Nocturne in C-sharp minor, Op. 27, No. 1. The anodyne thanks he received from Maria proved to be the last letter he was to have from her.
What was the first name of the girl Chopin proposed to?
A: Maria

Context and question: The legal administration of the death penalty in the United States is complex. Typically, it involves four critical steps: (1) sentencing, (2) direct review, (3) state collateral review, and (4) federal habeas corpus. Recently, a narrow and final fifth level of process (5) the Section 1983 challenge has become increasingly important. (Clemency or pardon, through which the Governor or President of the jurisdiction can unilaterally reduce or abrogate a death sentence, is an executive rather than judicial process.) The number of new death sentences handed down peaked in 19951996 (309). There were 73 new death sentences handed down in 2014, the lowest number since 1973 (44).
In the United States, how many important steps are never present in the administration of capital punishment?
Answer: unanswerable

Question: Full-featured USB Type-C cables are active, electronically marked cables that contain a chip with an ID function based on the configuration data channel and vendor-defined messages (VDMs) from the USB Power Delivery 2.0 specification. USB Type-C devices also support power currents of 1.5 A and 3.0 A over the 5 V power bus in addition to baseline 900 mA; devices can either negotiate increased USB current through the configuration line, or they can support the full Power Delivery specification using both BMC-coded configuration line and legacy BFSK-coded VBUS line.
Is there an answer to this question: What kind of cables does the fully featured USB Type-C contain?

Answer: active, electronically marked cables

But in statistical mechanics things get more complicated. On one hand, statistical mechanics is far superior to classical thermodynamics, in that thermodynamic behavior, such as glass breaking, can be explained by the fundamental laws of physics paired with a statistical postulate. But statistical mechanics, unlike classical thermodynamics, is time-reversal symmetric. The second law of thermodynamics, as it arises in statistical mechanics, merely states that it is overwhelmingly likely that net entropy will increase, but it is not an absolute law.
What type of mechanics help to simplify things?
A:
unanswerable
