Here is a question about this article: There are many important organozinc compounds. Organozinc chemistry is the science of organozinc compounds describing their physical properties, synthesis and reactions. Among important applications is the Frankland-Duppa Reaction in which an oxalate ester(ROCOCOOR) reacts with an alkyl halide R'X, zinc and hydrochloric acid to the -hydroxycarboxylic esters RR'COHCOOR, the Reformatskii reaction which converts -halo-esters and aldehydes to -hydroxy-esters, the SimmonsSmith reaction in which the carbenoid (iodomethyl)zinc iodide reacts with alkene(or alkyne) and converts them to cyclopropane, the Addition reaction of organozinc compounds to carbonyl compounds. The Barbier reaction (1899) is the zinc equivalent of the magnesium Grignard reaction and is better of the two. In presence of just about any water the formation of the organomagnesium halide will fail, whereas the Barbier reaction can even take place in water. On the downside organozincs are much less nucleophilic than Grignards, are expensive and difficult to handle. Commercially available diorganozinc compounds are dimethylzinc, diethylzinc and diphenylzinc. In one study the active organozinc compound is obtained from much cheaper organobromine precursors:
What is the answer to this question: What are dimethylzinc, dietylzinc and diphenylzinc?

So... Commercially available diorganozinc compounds

Here is a question about this article: The group changed their name to Destiny's Child in 1996, based upon a passage in the Book of Isaiah. In 1997, Destiny's Child released their major label debut song "Killing Time" on the soundtrack to the 1997 film, Men in Black. The following year, the group released their self-titled debut album, scoring their first major hit "No, No, No". The album established the group as a viable act in the music industry, with moderate sales and winning the group three Soul Train Lady of Soul Awards for Best R&B/Soul Album of the Year, Best R&B/Soul or Rap New Artist, and Best R&B/Soul Single for "No, No, No". The group released their multi-platinum second album The Writing's on the Wall in 1999. The record features some of the group's most widely known songs such as "Bills, Bills, Bills", the group's first number-one single, "Jumpin' Jumpin'" and "Say My Name", which became their most successful song at the time, and would remain one of their signature songs. "Say My Name" won the Best R&B Performance by a Duo or Group with Vocals and the Best R&B Song at the 43rd Annual Grammy Awards. The Writing's on the Wall sold more than eight million copies worldwide. During this time, Beyonce recorded a duet with Marc Nelson, an original member of Boyz II Men, on the song "After All Is Said and Done" for the soundtrack to the 1999 film, The Best Man.
What is the answer to this question: Destiny's Child song, Killing Time, was included in which film's soundtrack?
****
So... Men in Black.

Here is a question about this article: The ability of the Dominions to set their own foreign policy, independent of Britain, was recognised at the 1923 Imperial Conference. Britain's request for military assistance from the Dominions at the outbreak of the Chanak Crisis the previous year had been turned down by Canada and South Africa, and Canada had refused to be bound by the 1923 Treaty of Lausanne. After pressure from Ireland and South Africa, the 1926 Imperial Conference issued the Balfour Declaration, declaring the Dominions to be "autonomous Communities within the British Empire, equal in status, in no way subordinate one to another" within a "British Commonwealth of Nations". This declaration was given legal substance under the 1931 Statute of Westminster. The parliaments of Canada, Australia, New Zealand, the Union of South Africa, the Irish Free State and Newfoundland were now independent of British legislative control, they could nullify British laws and Britain could no longer pass laws for them without their consent. Newfoundland reverted to colonial status in 1933, suffering from financial difficulties during the Great Depression. Ireland distanced itself further from Britain with the introduction of a new constitution in 1937, making it a republic in all but name.
What is the answer to this question: When was the right of Dominions to determine their own foreign policy recognized?

So...
1923
