input: Make use of the article to answer the questions. Pitch is an auditory sensation in which a listener assigns musical tones to relative positions on a musical scale based primarily on their perception of the frequency of vibration. Pitch is closely related to frequency, but the two are not equivalent. Frequency is an objective, scientific attribute that can be measured. Pitch is each person's subjective perception of a sound, which cannot be directly measured. However, this does not necessarily mean that most people won't agree on which notes are higher and lower.

This creates a linear pitch space in which octaves have size 12, semitones (the distance between adjacent keys on the piano keyboard) have size 1, and A440 is assigned the number 69. (See Frequencies of notes.) Distance in this space corresponds to musical intervals as understood by musicians. An equal-tempered semitone is subdivided into 100 cents. The system is flexible enough to include "microtones" not found on standard piano keyboards. For example, the pitch halfway between C (60) and C (61) can be labeled 60.5. 1. What is pitch?

input: CHAPTER XLI. SPEECHIFYING.

On the Monday, a plowboy from Vale Regis arrived at Monksmoor.

In respect of himself, he was a person beneath notice. In respect of his errand, he was sufficiently important to cast a gloom over the household. The faithless Mirabel had broken his engagement, and the plowboy was the herald of misfortune who brought his apology. To his great disappointment (he wrote) he was detained by the affairs of his parish. He could only trust to Mr. Wyvil's indulgence to excuse him, and to communicate his sincere sense of regret (on scented note paper) to the ladies.

Everybody believed in the affairs of the parish--with the exception of Francine. "Mr. Mirabel has made the best excuse he could think of for shortening his visit; and I don't wonder at it," she said, looking significantly at Emily.

Emily was playing with one of the dogs; exercising him in the tricks which he had learned. She balanced a morsel of sugar on his nose--and had no attention to spare for Francine.

Cecilia, as the mistress of the house, felt it her duty to interfere. "That is a strange remark to make," she answered. "Do you mean to say that we have driven Mr. Mirabel away from us?"

"I accuse nobody," Francine began with spiteful candor.

"Now she's going to accuse everybody!" Emily interposed, addressing herself facetiously to the dog.

"But when girls are bent on fascinating men, whether they like it or not," Francine proceeded, "men have only one alternative--they must keep out of the way." She looked again at Emily, more pointedly than ever. 1. What was Vale Regis errand?

Q: Seoul, South Korea (CNN) -- Korean is considered one of the hardest languages in the world to master, but an elephant in a South Korean zoo is making a good start.

Koshik, a 22-year-old Asian elephant has stunned experts and his keepers at Everland Zoo near Seoul by imitating human speech. Koshik can say the Korean words for "hello," "sit down," "no," "lie down" and "good." His trainer, Kim Jong Gap, first started to realize Koshik was mimicking him several years ago.

""In 2004 and 2005, Kim didn't even know that the human voice he heard at the zoo was actually from Koshik," zoo spokesman In Kim In Cherl said. "But in 2006, he started to realize that Koshik had been imitating his voice and mentioned it to his boss."

Why do elephants have hair on their heads?

His boss initially called him "crazy."

Koshik's remarkable antics grabbed the interest of an elephant vocalization expert thousands of kilometers away at the University of Vienna in Austria.

""There was a YouTube video about Koshik vocalizing, and I was not sure if it was a fake, or if it was real," Dr. Angela Stoeger-Horwath said. She traveled with fellow expert Dr. Daniel Mietchen to South Korea in 2010 to test the elephant's ability. They recorded Koshik repeating certain words his keeper said and then played them for native Korean speakers to see, if they were recognizable.

"It is, for some of the sounds he makes, quite astonishing for how similar they are," said Mietchen of the University of Jena in Germany. "For instance the word 'choa' (meaning good) -- if you hear it right after what the keeper says -- it's quite similar."
