Problem: Frederic Chopin:

In London Chopin took lodgings at Dover Street, where the firm of Broadwood provided him with a grand piano. At his first engagement, on 15 May at Stafford House, the audience included Queen Victoria and Prince Albert. The Prince, who was himself a talented musician, moved close to the keyboard to view Chopin's technique. Broadwood also arranged concerts for him; among those attending were Thackeray and the singer Jenny Lind. Chopin was also sought after for piano lessons, for which he charged the high fee of one guinea (1.05 in present British currency) per hour, and for private recitals for which the fee was 20 guineas. At a concert on 7 July he shared the platform with Viardot, who sang arrangements of some of his mazurkas to Spanish texts.

What did Broadway provide for Chopin?

A: a grand piano.

Problem: Traditionally a carnival feast was the last opportunity to eat well before the time of food shortage at the end of the winter during which one was limited to the minimum necessary. On what nowadays is called vastenavond (the days before fasting) all the remaining winter stores of lard, butter and meat which were left would be eaten, for it would soon start to rot and decay. The selected livestock had in fact already been slaughtered in November and the meat would be no longer preservable. All the food that had survived the winter had to be eaten to assure that everyone was fed enough to survive until the coming spring would provide new food sources.
When would new food sources be available for those who survived the winter?

Answer: spring

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
There is disagreement about the origin of the term, but general consensus that "cardinalis" from the word cardo (meaning 'pivot' or 'hinge') was first used in late antiquity to designate a bishop or priest who was incorporated into a church for which he had not originally been ordained. In Rome the first persons to be called cardinals were the deacons of the seven regions of the city at the beginning of the 6th century, when the word began to mean "principal," "eminent," or "superior." The name was also given to the senior priest in each of the "title" churches (the parish churches) of Rome and to the bishops of the seven sees surrounding the city. By the 8th century the Roman cardinals constituted a privileged class among the Roman clergy. They took part in the administration of the church of Rome and in the papal liturgy. By decree of a synod of 769, only a cardinal was eligible to become pope. In 1059, during the pontificate of Nicholas II, cardinals were given the right to elect the pope under the Papal Bull In nomine Domini. For a time this power was assigned exclusively to the cardinal bishops, but the Third Lateran Council in 1179 gave back the right to the whole body of cardinals. Cardinals were granted the privilege of wearing the red hat by Pope Innocent IV in 1244.
What did the word cardinal begin to mean at the beginning of the 8th century?
A: unanswerable

Question: During this time, Link also helps Midna find the Fused Shadows, fragments of a relic containing powerful dark magic. In return, she helps Link find Ordon Village's children while helping the monkeys of Faron, the Gorons of Eldin, and the Zoras of Lanayru. Once Link has restored the Light Spirits and Midna has all the Fused Shadows, they are ambushed by Zant. After he relieves Midna of the Fused Shadow fragments, she ridicules him for abusing his tribe's magic, but Zant reveals that his power comes from another source as he uses it to turn Link back into a wolf, and then leaves Midna in Hyrule to die from the world's light. Bringing a dying Midna to Zelda, Link learns he needs the Master Sword to return to human form. Zelda sacrifices herself to heal Midna with her power before vanishing mysteriously. Midna is moved by Zelda's sacrifice, and begins to care more about Link and the fate of the light world.
Is there an answer to this question: What does Link assist Midna in collection?

Answer: Fused Shadows

Problem: Dialect:

The Sardinian language is considered to be its own Romance language family, separate not only from standard Italian but also the wider Italo-Dalmatian family, and it includes the Campidanese Sardinian and Logudorese Sardinian variants. However, Gallurese, Sassarese, and Corsican are also spoken in Sardinia, and these languages are considered closely related or derived from the Italian Tuscan language and thus are Italo-Dalmatian languages. Furthermore, the Gallo-Romance language of Ligurian and the Catalan Algherese dialect are also spoken in Sardinia.

Where is the Catalan Algherese dialect spoken?

A:
Sardinian
