Problem: Please answer a question about the following article about Mexico City:
Mexico city primarily rests on what was Lake Texcoco. Seismic activity is frequent here. Lake Texcoco was drained starting from the 17th century. Although none of the lake waters remain, the city rests on the lake bed's heavily saturated clay. This soft base is collapsing due to the over-extraction of groundwater, called groundwater-related subsidence. Since the beginning of the 20th century the city has sunk as much as nine metres (30 feet) in some areas. This sinking is causing problems with runoff and wastewater management, leading to flooding problems, especially during the rainy season. The entire lake bed is now paved over and most of the city's remaining forested areas lie in the southern boroughs of Milpa Alta, Tlalpan and Xochimilco.
When did draining of Lake Texcoco begin?
A: 17th century
Problem: Please answer a question about the following article about Chinese characters:
One man who has encountered this problem is Taiwanese politician Yu Shyi-kun, due to the rarity of the last character in his name. Newspapers have dealt with this problem in varying ways, including using software to combine two existing, similar characters, including a picture of the personality, or, especially as is the case with Yu Shyi-kun, simply substituting a homophone for the rare character in the hope that the reader would be able to make the correct inference. Taiwanese political posters, movie posters etc. will often add the bopomofo phonetic symbols next to such a character. Japanese newspapers may render such names and words in katakana instead of kanji, and it is accepted practice for people to write names for which they are unsure of the correct kanji in katakana instead.
What will often add bopomofo phonetic symbols?
A: movie posters
