Question: Pesticides can be classified by target organism (e.g., herbicides, insecticides, fungicides, rodenticides, and pediculicides - see table), chemical structure (e.g., organic, inorganic, synthetic, or biological (biopesticide), although the distinction can sometimes blur), and physical state (e.g. gaseous (fumigant)). Biopesticides include microbial pesticides and biochemical pesticides. Plant-derived pesticides, or "botanicals", have been developing quickly. These include the pyrethroids, rotenoids, nicotinoids, and a fourth group that includes strychnine and scilliroside.:15

Question: Chopin's polonaises show a marked advance on those of his Polish predecessors in the form (who included his teachers Zywny and Elsner). As with the traditional polonaise, Chopin's works are in triple time and typically display a martial rhythm in their melodies, accompaniments and cadences. Unlike most of their precursors, they also require a formidable playing technique.
Is there an answer to this question: Chopin's polonaises needed what kind of playing technique?

Answer: formidable

Question: When comparing different documents, or "witnesses", of a single, original text, the observed differences are called variant readings, or simply variants or readings. It is not always apparent which single variant represents the author's original work. The process of textual criticism seeks to explain how each variant may have entered the text, either by accident (duplication or omission) or intention (harmonization or censorship), as scribes or supervisors transmitted the original author's text by copying it. The textual critic's task, therefore, is to sort through the variants, eliminating those most likely to be un-original, hence establishing a "critical text", or critical edition, that is intended to best approximate the original. At the same time, the critical text should document variant readings, so the relation of extant witnesses to the reconstructed original is apparent to a reader of the critical edition. In establishing the critical text, the textual critic considers both "external" evidence (the age, provenance, and affiliation of each witness) and "internal" or "physical" considerations (what the author and scribes, or printers, were likely to have done).
Is there an answer to this question: When do variations enter a witness text?

Answer: unanswerable

Question: From the league's inception through ArenaBowl XVIII, the championship game was played at the home of the highest-seeded remaining team. The AFL then switched to a neutral-site championship, with ArenaBowls XIX and XX in Las Vegas. New Orleans Arena, home of the New Orleans VooDoo, served as the site of ArenaBowl XXI on July 29, 2007. This was the first professional sports championship to be staged in the city since Hurricane Katrina struck in August 2005. The San Jose SaberCats earned their third championship in six years by defeating the Columbus Destroyers 5533. ArenaBowl XXI in New Orleans was deemed a success, and the city was chosen to host ArenaBowl XXII, in which the Philadelphia Soul defeated the defending champion San Jose Sabercats. In 2010, the location returned to being decided by which of the two participating teams was seeded higher. In ArenaBowl XXIII, the Spokane Shock defeated the Tampa Bay Storm at their home arena, Spokane Arena, in Spokane, Washington. In ArenaBowl XXIV, the Jacksonville Sharks, coming off of a victory in their conference final game four nights earlier, traveled to US Airways Center in Phoenix and defeated the Arizona Rattlers 7370. ArenaBowl XXV returned to a neutral site and was once again played in New Orleans, where the Rattlers returned and defeated the Philadelphia Soul. Since 2014 the ArenaBowl has been played at the higher-seeded team.
Is there an answer to this question: What team won ArenaBowl XXI?

Answer:
San Jose SaberCats
