[EX Q]: Passage: On 24 August, Pravda and Izvestia carried news of the non-secret portions of the Pact, complete with the now infamous front-page picture of Molotov signing the treaty, with a smiling Stalin looking on. The news was met with utter shock and surprise by government leaders and media worldwide, most of whom were aware only of the British–French–Soviet negotiations that had taken place for months. The Molotov–Ribbentrop Pact was received with shock by Nazi Germany's allies, notably Japan, by the Comintern and foreign communist parties, and by Jewish communities all around the world. So, that day, German diplomat Hans von Herwarth, whose grandmother was Jewish, informed Guido Relli, an Italian diplomat, and American chargé d'affaires Charles Bohlen on the secret protocol regarding vital interests in the countries' allotted "spheres of influence", without revealing the annexation rights for "territorial and political rearrangement".
[EX A]: Which diplomat never leaked information about the secret agreements?

[EX Q]: Passage: If the Governor General of Canada is unable to give assent, it can be done by either the Deputy of the Governor General of Canada—the Chief Justice of Canada—or another justice of the Supreme Court of Canada. It is not actually necessary for the governor general to sign a bill passed by a legislature, the signature being merely an attestation. In each case, the parliament must be apprised of the granting of assent before the bill is considered to have become law. Two methods are available: the sovereign's representatives may grant assent in the presence of both houses of parliament; alternatively, each house may be notified separately, usually by the speaker of that house. However, though both houses must be notified on the same day, notice to the House of Commons while it is not in session may be given by way of publishing a special issue of the Journals of the House of Commons, whereas the Senate must be sitting and the governor general's letter read aloud by the speaker.
[EX A]: It is necessary for the governor general to sign what?

[EX Q]: Passage: Back in America the scene had still not progressed beyond a small number of clubs in Chicago, Detroit, Newark and New York City. However, many independent Chicago-based record labels were making appearances on the Dance Chart with their releases. In the UK, any house song released by a Chicago-based label was routinely considered a must play at many clubs playing house music. Paradise Garage in New York City was still a top club. The emergence of Todd Terry, a pioneer of the genre, was important in America. His cover of Class Action's Larry Levan mixed "Weekend" demonstrated the continuum from the underground disco to a new house sound with hip-hop influences evident in the quicker sampling and the more rugged bass-line.
[EX A]:
What was a top club for house music in Detroit?
