[EX Q]: Passage: Poetry, in particular, was a staple of court life. Nobles and ladies-in-waiting were expected to be well versed in the art of writing poetry as a mark of their status. Every occasion could call for the writing of a verse, from the birth of a child to the coronation of an emperor, or even a pretty scene of nature. A well-written poem or haiku could easily make or break one's reputation, and often was a key part of social interaction.Almost as important was the choice of calligraphy, or handwriting, used. The Japanese of this period believed handwriting could reflect the condition of a person's soul: therefore, poor or hasty writing could be considered a sign of poor breeding. Whether the script was Chinese or Japanese, good writing and artistic skill was paramount to social reputation when it came to poetry. Sei Shonagon mentions in her Pillow Book that when a certain courtesan tried to ask her advice about how to write a poem to the empress Sadako, she had to politely rebuke him because his writing was so poor.
[EX A]: Who was expected to be able to read poetry?

[EX Q]: Passage: Elizabeth has held many titles and honorary military positions throughout the Commonwealth, is Sovereign of many orders in her own countries, and has received honours and awards from around the world. In each of her realms she has a distinct title that follows a similar formula: Queen of Jamaica and her other realms and territories in Jamaica, Queen of Australia and her other realms and territories in Australia, etc. In the Channel Islands and Isle of Man, which are Crown dependencies rather than separate realms, she is known as Duke of Normandy and Lord of Mann, respectively. Additional styles include Defender of the Faith and Duke of Lancaster. When in conversation with the Queen, the practice is to initially address her as Your Majesty and thereafter as Ma'am.
[EX A]: What is one of Elizabeth's realms and territories besides Jamaica and Australia?

[EX Q]: Passage: In four months, Aonuma's team managed to present realistic horseback riding,[l] which Nintendo later revealed to the public with a trailer at Electronic Entertainment Expo 2004. The game was scheduled to be released the next year, and was no longer a follow-up to The Wind Waker; a true sequel to it was released for the Nintendo DS in 2007, in the form of Phantom Hourglass. Miyamoto explained in interviews that the graphical style was chosen to satisfy demand, and that it better fit the theme of an older incarnation of Link. The game runs on a modified The Wind Waker engine.
[EX A]:
How long did it take to implement riding Phantoms in a believable manner?
