Why did Cubitt build the new wing?, Context: By 1847, the couple had found the palace too small for court life and their growing family, and consequently the new wing, designed by Edward Blore, was built by Thomas Cubitt, enclosing the central quadrangle. The large East Front, facing The Mall, is today the "public face" of Buckingham Palace, and contains the balcony from which the royal family acknowledge the crowds on momentous occasions and after the annual Trooping the Colour. The ballroom wing and a further suite of state rooms were also built in this period, designed by Nash's student Sir James Pennethorne.

Which of the following is a character system: Fujian, Teochew, or pinyin?, Context: Hokkien /hɒˈkiɛn/ (traditional Chinese: 福建話; simplified Chinese: 福建话; pinyin: Fújiànhuà; Pe̍h-ōe-jī: Hok-kiàn oē) or Quanzhang (Quanzhou–Zhangzhou / Chinchew–Changchew; BP: Zuánziū–Ziāngziū) is a group of mutually intelligible Min Nan Chinese dialects spoken throughout Southeast Asia, Taiwan, and by many other overseas Chinese. Hokkien originated from a dialect in southern Fujian. It is closely related to the Teochew, though mutual comprehension is difficult, and is somewhat more distantly related to Hainanese. Besides Hokkien, there are also other Min and Hakka dialects in Fujian province, most of which are not mutually intelligible with Hokkien.

Besides the playback system how were acoustic limitations negatively affected?, Context: Delicate sounds and fine overtones were mostly lost, because it took a lot of sound energy to vibrate the recording horn diaphragm and cutting mechanism. There were acoustic limitations due to mechanical resonances in both the recording and playback system. Some pictures of acoustic recording sessions show horns wrapped with tape to help mute these resonances. Even an acoustic recording played back electrically on modern equipment sounds like it was recorded through a horn, notwithstanding a reduction in distortion because of the modern playback. Toward the end of the acoustic era, there were many fine examples of recordings made with horns.
