Q: what is the last section of a city mentioned?, Context: Philadelphia's central city was created in the 17th century following the plan by William Penn's surveyor Thomas Holme. Center City is structured with long straight streets running east-west and north-south forming a grid pattern. The original city plan was designed to allow for easy travel and to keep residences separated by open space that would help prevent the spread of fire. The Delaware River and Schuylkill Rivers served as early boundaries between which the city's early street plan was kept within. In addition, Penn planned the creation of five public parks in the city which were renamed in 1824 (in parenthesis): Centre Square, North East Publick Square (Franklin Square), Northwest Square (Logan Square), Southwest Square (Rittenhouse Square), and Southeast Square (Washington Square). Center City has grown into the second-most populated downtown area in the United States, after Midtown Manhattan in New York City, with an estimated 183,240 residents in 2015.

A: Midtown Manhattan

Q: How does bass drum does not sound?, Context: It is still possible for two sounds of indefinite pitch to clearly be higher or lower than one another. For instance, a snare drum sounds higher pitched than a bass drum though both have indefinite pitch, because its sound contains higher frequencies. In other words, it is possible and often easy to roughly discern the relative pitches of two sounds of indefinite pitch, but sounds of indefinite pitch do not neatly correspond to any specific pitch. A special type of pitch often occurs in free nature when sound reaches the ear of an observer directly from the source, and also after reflecting off a sound-reflecting surface. This phenomenon is called repetition pitch, because the addition of a true repetition of the original sound to itself is the basic prerequisite.

A: higher pitched

Q: What tribe did Borte join unwillingly?, Context: As previously arranged by his father, Temüjin married Börte of the Onggirat tribe when he was around 16 in order to cement alliances between their respective tribes. Soon after Börte's marriage to Temüjin, she was kidnapped by the Merkits and reportedly given away as a wife. Temüjin rescued her with the help of his friend and future rival, Jamukha, and his protector, Toghrul Khan of the Keraite tribe. She gave birth to a son, Jochi (1185–1226), nine months later, clouding the issue of his parentage. Despite speculation over Jochi, Börte would be Temüjin's only empress, though he did follow tradition by taking several morganatic wives.

A:
Merkits
