[Q]: Question: "What art form mentioned is post 19th century?"  Context: "During the 19th century, an important producer of art was the Academia de San Carlos (San Carlos Art Academy), founded during colonial times, and which later became the Escuela Nacional de Artes Plásticas (the National School of Arts) including painting, sculpture and graphic design, one of UNAM's art schools. Many of the works produced by the students and faculty of that time are now displayed in the Museo Nacional de San Carlos (National Museum of San Carlos). One of the students, José María Velasco, is considered one of the greatest Mexican landscape painters of the 19th century. Porfirio Díaz's regime sponsored arts, especially those that followed the French school. Popular arts in the form of cartoons and illustrations flourished, e.g. those of José Guadalupe Posada and Manuel Manilla. The permanent collection of the San Carlos Museum also includes paintings by European masters such as Rembrandt, Velázquez, Murillo, and Rubens."  Answer:

[Q]: Question: "Besides Mexico where did painters come from?"  Context: "During the 20th century, many artists immigrated to Mexico City from different regions of Mexico, such as Leopoldo Méndez, an engraver from Veracruz, who supported the creation of the socialist Taller de la Gráfica Popular (Popular Graphics Workshop), designed to help blue-collar workers find a venue to express their art. Other painters came from abroad, such as Catalan painter Remedios Varo and other Spanish and Jewish exiles. It was in the second half of the 20th century that the artistic movement began to drift apart from the Revolutionary theme. José Luis Cuevas opted for a modernist style in contrast to the muralist movement associated with social politics."  Answer:
****
[A]: Catalan painter Remedios Varo and other Spanish and Jewish exiles


[Q]: Question: "What can be found in this era and others?"  Context: "During the Miocene continents continued to drift toward their present positions. Of the modern geologic features, only the land bridge between South America and North America was absent, the subduction zone along the Pacific Ocean margin of South America caused the rise of the Andes and the southward extension of the Meso-American peninsula. India continued to collide with Asia. The Tethys Seaway continued to shrink and then disappeared as Africa collided with Eurasia in the Turkish-Arabian region between 19 and 12 Ma (ICS 2004). Subsequent uplift of mountains in the western Mediterranean region and a global fall in sea levels combined to cause a temporary drying up of the Mediterranean Sea resulting in the Messinian salinity crisis near the end of the Miocene."  Answer:
****
[A]: land bridge between South America and North America
