Problem: Background: Indigenous peoples of Mexico (Spanish: pueblos indigenas de Mexico), Native Mexicans (Spanish: nativos mexicanos), or Mexican Native Americans (Spanish: nativo america mexicanos), are those who are part of communities that trace their roots back to populations and communities that existed in what is now Mexico prior to the arrival of Europeans. According to the National Commission for the Development of Indigenous Peoples (Comision Nacional para el Desarrollo de los Pueblos Indigenas, or CDI in Spanish) and the INEGI (official census institute), in 2015, 25,694,928 people in Mexico self-identify as being indigenous of many different ethnic groups, which constitute 21.5% of Mexico's population.
Context: The Law of Linguistic Rights of the Indigenous Languages recognizes 62 indigenous languages as "national languages" which have the same validity as Spanish in all territories where they are spoken. According to the National Institute of Statistics, Geography and Data Processing (INEGI), approximately 6.7% of the population speaks an indigenous language. That is, less than half of those identified as indigenous. 6,695,228 people 5 years or older were tallied as indigenous-language speakers in the 2010 census, an increase of about 650,000 from the 2000 census. In 2000, 6,044,547 people 5 years or older spoke an indigenous language. In previous censuses, information on the indigenous speaking population five years of age and older was obtained from the Mexican people. However, in the 2010 census, this approach was changed and the Government also began to collect data on people 3 years and older because from the age of 3, children are able to communicate verbally. With this new approach, it was determined that there were 6,913,362 people 3 years of age or more who spoke an indigenous language (218,000 children 3 and 4 four years of age fell into this category), accounting for 6.6% of the total population. The population of children aged 0 to 2 years in homes where the head of household or a spouse spoke an indigenous language was 678 954. The indigenous language speaking population has been increasing in absolute numbers for decades, but have nonetheless been falling in proportion to the national population. The recognition of indigenous languages and the protection of indigenous cultures is granted not only to the ethnic groups indigenous to modern-day Mexican territory, but also to other North American indigenous groups that migrated to Mexico from the United States in the nineteenth century and those who immigrated from Guatemala in the 1980s.
Question: What is the most popular (or a few of the most spoken) language(s) from these 62 ?
Answer: which have the same validity as Spanish in all territories where they are spoken.

Background: Hans Holbein the Younger (German: Hans Holbein der Jungere) (c. 1497 - between 7 October and 29 November 1543) was a German artist and printmaker who worked in a Northern Renaissance style. He is best known as one of the greatest portraitists of the 16th century. He also produced religious art, satire and Reformation propaganda, and made a significant contribution to the history of book design.
Context: On 29 August 1528, Holbein bought a house in Basel, in St Johanns-Vorstadt. He presumably returned home to preserve his citizenship, since he had been granted only a two-year leave of absence. Enriched by his success in England, Holbein bought a second house in the city in 1531. During this period in Basel, he painted The Artist's Family, showing Elsbeth, with the couple's two eldest children, Philipp and Katherina, evoking images of the Virgin and Child with St John the Baptist. Art historian John Rowlands sees this work as "one of the most moving portraits in art, from an artist, too, who always characterized his sitters with a guarded restraint". Basel had become a turbulent city in Holbein's absence. Reformers, swayed by the ideas of Zwingli, carried out acts of iconoclasm and banned imagery in churches. In April 1529, the free-thinking Erasmus felt obliged to leave his former haven for Freiburg im Breisgau. The iconoclasts probably destroyed some of Holbein's religious artwork, but details are unknown. Evidence for Holbein's religious views is fragmentary and inconclusive. "The religious side of his paintings had always been ambiguous," suggests art historian John North, "and so it remained". According to a register compiled to ensure that all major citizens subscribed to the new doctrines: "Master Hans Holbein, the painter, says that we must be better informed about the [holy] table before approaching it". In 1530, the authorities called Holbein to account for failing to attend the reformed communion. Shortly afterwards, however, he was listed among those "who have no serious objections and wish to go along with other Christians". Holbein evidently retained favour under the new order. The reformist council paid him a retaining fee of 50 florins and commissioned him to resume work on the Council Chamber frescoes. They now chose themes from the Old Testament instead of the previous stories from classical history and allegory. Holbein's frescoes of Rehoboam and of the meeting between Saul and Samuel were more simply designed than their predecessors. Holbein worked for traditional clients at the same time. His old patron Jakob Meyer paid him to add figures and details to the family altarpiece he had painted in 1526. Holbein's last commission in this period was the decoration of two clock faces on the city gate in 1531. The reduced levels of patronage in Basel may have prompted his decision to return to England early in 1532.
Question: What was significant about the house?
Answer:
Enriched by his success in England, Holbein bought a second house in the city in 1531.
