Article: Since life began on Earth, five major mass extinctions and several minor events have led to large and sudden drops in biodiversity. The Phanerozoic eon (the last 540 million years) marked a rapid growth in biodiversity via the Cambrian explosiona period during which the majority of multicellular phyla first appeared. The next 400 million years included repeated, massive biodiversity losses classified as mass extinction events. In the Carboniferous, rainforest collapse led to a great loss of plant and animal life. The PermianTriassic extinction event, 251 million years ago, was the worst; vertebrate recovery took 30 million years. The most recent, the CretaceousPaleogene extinction event, occurred 65 million years ago and has often attracted more attention than others because it resulted in the extinction of the dinosaurs.

Question: How long did vertebrate recovery take?
Ans: 30 million years

Here is a question about this article: Following Die Another Day, Madonna collaborated with fashion photographer Steven Klein in 2003 for an exhibition installation named X-STaTIC Pro=CeSS. It included photography from a photo shoot in W magazine, and seven video segments. The installation ran from March to May in New York's Deitch Projects gallery. It traveled the world in an edited form. The same year, Madonna released her ninth studio album, American Life, which was based on her observations of American society; it received mixed reviews. She commented, "[American Life] was like a trip down memory lane, looking back at everything I've accomplished and all the things I once valued and all the things that were important to me." Larry Flick from The Advocate felt that "American Life is an album that is among her most adventurous and lyrically intelligent" while condemning it as "a lazy, half-arsed effort to sound and take her seriously." The title song peaked at number 37 on the Hot 100. Its original music video was canceled as Madonna thought that the video, featuring violence and war imagery, would be deemed unpatriotic since America was then at war with Iraq. With four million copies sold worldwide, American Life was the lowest-selling album of her career at that point.
What is the answer to this question: American Life reached which number at the Hot 100?
****
So... 37

Beyonce and her mother introduced House of Dereon, a contemporary women's fashion line, in 2005.

Problem: Please answer a question about the following article about Beyonce:
On April 4, 2008, Beyonce married Jay Z. She publicly revealed their marriage in a video montage at the listening party for her third studio album, I Am... Sasha Fierce, in Manhattan's Sony Club on October 22, 2008. I Am... Sasha Fierce was released on November 18, 2008 in the United States. The album formally introduces Beyonce's alter ego Sasha Fierce, conceived during the making of her 2003 single "Crazy in Love", selling 482,000 copies in its first week, debuting atop the Billboard 200, and giving Beyonce her third consecutive number-one album in the US. The album featured the number-one song "Single Ladies (Put a Ring on It)" and the top-five songs "If I Were a Boy" and "Halo". Achieving the accomplishment of becoming her longest-running Hot 100 single in her career, "Halo"'s success in the US helped Beyonce attain more top-ten singles on the list than any other woman during the 2000s. It also included the successful "Sweet Dreams", and singles "Diva", "Ego", "Broken-Hearted Girl" and "Video Phone". The music video for "Single Ladies" has been parodied and imitated around the world, spawning the "first major dance craze" of the Internet age according to the Toronto Star. The video has won several awards, including Best Video at the 2009 MTV Europe Music Awards, the 2009 Scottish MOBO Awards, and the 2009 BET Awards. At the 2009 MTV Video Music Awards, the video was nominated for nine awards, ultimately winning three including Video of the Year. Its failure to win the Best Female Video category, which went to American country pop singer Taylor Swift's "You Belong with Me", led to Kanye West interrupting the ceremony and Beyonce improvising a re-presentation of Swift's award during her own acceptance speech. In March 2009, Beyonce embarked on the I Am... World Tour, her second headlining worldwide concert tour, consisting of 108 shows, grossing $119.5 million.
How did she reveal the marriage?

During his life and especially in the first year after his death, several places were named after Tito. Several of these places have since returned to their original names, such as Podgorica, formerly Titograd (though Podgorica's international airport is still identified by the code TGD), and Uzice, formerly Titovo Uzice, which reverted to its original name in 1992. Streets in Belgrade, the capital, have all reverted to their original preWorld War II and pre-communist names as well. In 2004, Antun Augustincic's statue of Broz in his birthplace of Kumrovec was decapitated in an explosion. It was subsequently repaired. Twice in 2008, protests took place in Zagreb's Marshal Tito Square, organized by a group called Circle for the Square (Krug za Trg), with an aim to force the city government to rename it to its previous name, while a counter-protest by Citizens' Initiative Against Ustasism (Graanska inicijativa protiv ustastva) accused the "Circle for the Square" of historical revisionism and neo-fascism. Croatian president Stjepan Mesic criticized the demonstration to change the name. In the Croatian coastal city of Opatija the main street (also its longest street) still bears the name of Marshal Tito, as do streets in numerous towns in Serbia, mostly in the country's north. One of the main streets in downtown Sarajevo is called Marshal Tito Street, and Tito's statue in a park in front of the university campus (ex. JNA barrack "Marsal Tito") in Marijin Dvor is a place where Bosnians and Sarajevans still today commemorate and pay tribute to Tito (image on the right). The largest Tito monument in the world, about 10 m (33 ft) high, is located at Tito Square (Slovene: Titov trg), the central square in Velenje, Slovenia. One of the main bridges in Slovenia's second largest city of Maribor is Tito Bridge (Titov most). The central square in Koper, the largest Slovenian port city, is as well named Tito Square.
