Problem: Annelid:

Traditionally the annelids have been divided into two major groups, the polychaetes and clitellates. In turn the clitellates were divided into oligochaetes, which include earthworms, and hirudinomorphs, whose best-known members are leeches. For many years there was no clear arrangement of the approximately 80 polychaete families into higher-level groups. In 1997 Greg Rouse and Kristian Fauchald attempted a "first heuristic step in terms of bringing polychaete systematics to an acceptable level of rigour", based on anatomical structures, and divided polychaetes into:

How many polychaete families are there?
---
A: approximately 80


Problem: Legislative powers are exercised by a 300-member elective unicameral Parliament. Statutes passed by the Parliament are promulgated by the President of the Republic.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In July 2010, Governor Chris Christie announced that a state takeover of the city and local government "was imminent". Comparing regulations in Atlantic City to an "antique car", Atlantic City regulatory reform is a key piece of Gov. Chris Christie's plan, unveiled on July 22, to reinvigorate an industry mired in a four-year slump in revenue and hammered by fresh competition from casinos in the surrounding states of Delaware, Pennsylvania, Connecticut, and more recently, Maryland. In January 2011, Chris Christie announced the Atlantic City Tourism District, a state-run district encompassing the boardwalk casinos, the marina casinos, the Atlantic City Outlets, and Bader Field. Fairleigh Dickinson University's PublicMind poll surveyed New Jersey voters' attitudes on the takeover. The February 16, 2011 survey showed that 43% opposed the measure while 29% favored direct state oversight. Interestingly, the poll also found that even South Jersey voters expressed opposition to the plan; 40% reported they opposed the measure and 37% reported they were in favor of it.
According to a poll, what percentage of New Jersey voters opposed the takeover of Atlantic City by the state?
A: 43%


Context and question: Although Foo Fighters continued to be one of the most successful rock acts, with albums like In Your Honor (2005) reaching number two in the US and UK, many of the first wave of post-grunge bands began to fade in popularity. Acts like Creed, Staind, Puddle of Mudd and Nickelback took the genre into the 2000s with considerable commercial success, abandoning most of the angst and anger of the original movement for more conventional anthems, narratives and romantic songs. They were followed in this vein by new acts including Shinedown and Seether. Acts with more conventional hard rock sounds included Andrew W.K., Beautiful Creatures and Buckcherry, whose breakthrough album 15 (2006) went platinum and spawned the single "Sorry" (2007), which made the Top 10 of the Billboard 100. These were joined by bands with hard rock leanings that emerged in the mid-2000s from the garage rock or post punk revival, including Black Rebel Motorcycle Club and Kings of Leon, and Queens of the Stone Age from the US, Three Days Grace from Canada, Jet from Australia and The Datsuns from New Zealand. In 2009 Them Crooked Vultures, a supergroup that brought together Foo Fighters' Dave Grohl, Queens of the Stone Age's Josh Homme and Led Zeppelin bass player John Paul Jones attracted attention as a live act and released a self-titled debut album that reached the top 20 in the US and UK and the top ten in several other countries.
What was the title of Buckcherry's 2007 hit single?
Answer: "Sorry"


Question: Hoping to extend the Continental System, Napoleon invaded Iberia and declared his brother Joseph the King of Spain in 1808. The Spanish and the Portuguese revolted with British support. The Peninsular War lasted six years, noted for its brutal guerrilla warfare, and culminated in an Allied victory. Fighting also erupted in Central Europe, as the Austrians launched another attack against the French in 1809. Napoleon defeated them at the Battle of Wagram, dissolving the Fifth Coalition formed against France. By 1811, Napoleon ruled over 70 million people across an empire that had domination in Europe, which had not witnessed this level of political consolidation since the days of the Roman Empire. He maintained his strategic status through a series of alliances and family appointments. He created a new aristocracy in France while allowing the return of nobles who had been forced into exile by the Revolution.
Is there an answer to this question: Who did Napoleon declare King of Spain in 1808?

Answer: his brother Joseph


Question: According to historian Shaye J. D. Cohen, the status of the offspring of mixed marriages was determined patrilineally in the Bible. He brings two likely explanations for the change in Mishnaic times: first, the Mishnah may have been applying the same logic to mixed marriages as it had applied to other mixtures (Kil'ayim). Thus, a mixed marriage is forbidden as is the union of a horse and a donkey, and in both unions the offspring are judged matrilineally. Second, the Tannaim may have been influenced by Roman law, which dictated that when a parent could not contract a legal marriage, offspring would follow the mother.
Is there an answer to this question: What unions were allowed along with mixed marriages?

Answer:
unanswerable
