[EX Q]: Passage: The Canadian constitution determines that the Commander-in-Chief of the Canadian Armed Forces is the country's sovereign, who, since 1904, has authorized his or her viceroy, the governor general, to exercise the duties ascribed to the post of Commander-in-Chief and to hold the associated title since 1905. All troop deployment and disposition orders, including declarations of war, fall within the royal prerogative and are issued as Orders in Council, which must be signed by either the monarch or governor general. Under the Westminster system's parliamentary customs and practices, however, the monarch and viceroy must generally follow the advice of his or her ministers in Cabinet, including the prime minister and minister of national defence, who are accountable to the elected House of Commons. Question: Who does the Commander-in-Chief authorize to make decision regarding the Armed Forces for them?
[EX A]: the governor general

[EX Q]: Passage: Almost all animals are capable of modifying their behavior as a result of experienceeven the most primitive types of worms. Because behavior is driven by brain activity, changes in behavior must somehow correspond to changes inside the brain. Theorists dating back to Santiago Ramon y Cajal argued that the most plausible explanation is that learning and memory are expressed as changes in the synaptic connections between neurons. Until 1970, however, experimental evidence to support the synaptic plasticity hypothesis was lacking. In 1971 Tim Bliss and Terje Lmo published a paper on a phenomenon now called long-term potentiation: the paper showed clear evidence of activity-induced synaptic changes that lasted for at least several days. Since then technical advances have made these sorts of experiments much easier to carry out, and thousands of studies have been made that have clarified the mechanism of synaptic change, and uncovered other types of activity-driven synaptic change in a variety of brain areas, including the cerebral cortex, hippocampus, basal ganglia, and cerebellum. Brain-derived neurotrophic factor (BDNF) and physical activity appear to play a beneficial role in the process. Question: In what year did Tim Bliss and Terje Lomo publish a paper about long-term potentiation?
[EX A]:
1971
