Problem: The 1960s was a significant decade for Iranian cinema, with 25 commercial films produced annually on average throughout the early 60s, increasing to 65 by the end of the decade. The majority of production focused on melodrama and thrillers. With the screening of the films Kaiser and The Cow, directed by Masoud Kimiai and Dariush Mehrjui respectively in 1969, alternative films established their status in the film industry. Attempts to organize a film festival that had begun in 1954 within the framework of the Golrizan Festival, bore fruits in the form of the Sepas Festival in 1969. The endeavors also resulted in the formation of the Tehran World Festival in 1973.
How many commercial films were produced yearly on average by the end of the 1960s in Iran?

Answer: 65


Problem: The chemistry of zinc is dominated by the +2 oxidation state. When compounds in this oxidation state are formed the outer shell s electrons are lost, which yields a bare zinc ion with the electronic configuration [Ar]3d10. In aqueous solution an octahedral complex, [Zn(H
2O)6]2+ is the predominant species. The volatilization of zinc in combination with zinc chloride at temperatures above 285 °C indicates the formation of Zn
2Cl
2, a zinc compound with a +1 oxidation state. No compounds of zinc in oxidation states other than +1 or +2 are known. Calculations indicate that a zinc compound with the oxidation state of +4 is unlikely to exist.
What oxidation state dominates zinc?

Answer: +2


Problem: Following the disbandment of Destiny's Child in June 2005, she released her second solo album, B'Day (2006), which contained hits "Déjà Vu", "Irreplaceable", and "Beautiful Liar". Beyoncé also ventured into acting, with a Golden Globe-nominated performance in Dreamgirls (2006), and starring roles in The Pink Panther (2006) and Obsessed (2009). Her marriage to rapper Jay Z and portrayal of Etta James in Cadillac Records (2008) influenced her third album, I Am... Sasha Fierce (2008), which saw the birth of her alter-ego Sasha Fierce and earned a record-setting six Grammy Awards in 2010, including Song of the Year for "Single Ladies (Put a Ring on It)". Beyoncé took a hiatus from music in 2010 and took over management of her career; her fourth album 4 (2011) was subsequently mellower in tone, exploring 1970s funk, 1980s pop, and 1990s soul. Her critically acclaimed fifth studio album, Beyoncé (2013), was distinguished from previous releases by its experimental production and exploration of darker themes.
