Problem: Pollination is the process by which pollen is transferred in the reproduction of plants, thereby enabling fertilisation and sexual reproduction. Most flowering plants require an animal to do the transportation. While other animals are included as pollinators, the majority of pollination is done by insects. Because insects usually receive benefit for the pollination in the form of energy rich nectar it is a grand example of mutualism. The various flower traits (and combinations thereof) that differentially attract one type of pollinator or another are known as pollination syndromes. These arose through complex plant-animal adaptations. Pollinators find flowers through bright colorations, including ultraviolet, and attractant pheromones. The study of pollination by insects is known as anthecology.
What is required to transport pollen?

Answer: an animal

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
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 Romance Algherese dialect spoken?
A: unanswerable

Context and question: After four years on the sidelines, Austria sought another war with France to avenge its recent defeats. Austria could not count on Russian support because the latter was at war with Britain, Sweden, and the Ottoman Empire in 1809. Frederick William of Prussia initially promised to help the Austrians, but reneged before conflict began. A report from the Austrian finance minister suggested that the treasury would run out of money by the middle of 1809 if the large army that the Austrians had formed since the Third Coalition remained mobilized. Although Archduke Charles warned that the Austrians were not ready for another showdown with Napoleon, a stance that landed him in the so-called "peace party," he did not want to see the army demobilized either. On 8 February 1809, the advocates for war finally succeeded when the Imperial Government secretly decided on another confrontation against the French.
Who was the Prussian ruler who at first claimed he would help Austria in its battle with France, but later refused to?
Answer: Frederick William

Question: From the 1980s, mainstream sensibilities were reasserted and serialization became less common as the number of comics magazines decreased and many comics began to be published directly as albums. Smaller publishers such as L'Association that published longer works in non-traditional formats by auteur-istic creators also became common. Since the 1990s, mergers resulted in fewer large publishers, while smaller publishers proliferated. Sales overall continued to grow despite the trend towards a shrinking print market.
Is there an answer to this question: Serialization of newspapers became less popular when?

Answer: unanswerable

Question: Sectional tensions had long existed between the states located north of the MasonDixon line and those south of it, primarily centered on the "peculiar institution" of slavery and the ability of states to overrule the decisions of the national government. During the 1840s and 1850s, conflicts between the two sides became progressively more violent. After the election of Abraham Lincoln in 1860 (who southerners thought would work to end slavery) states in the South seceded from the United States, beginning with South Carolina in late 1860. On April 12, 1861, forces of the South (known as the Confederate States of America or simply the Confederacy) opened fire on Fort Sumter, whose garrison was loyal to the Union.
Is there an answer to this question: When did Confederate forces bombard Fort Sumter?

Answer:
April 12, 1861
