Q: This task involves creating questions from a given passage that involve some kind of complex reasoning (including numerical reasoning).
The generated questions must require looking at more than one part of the passage to answer. Try to use a variety of reasoning types in your questions (some of the sample reasoning types are illustrated in the 'positive examples' field) and also have a variety of answer types (spans, numbers, dates). A span is a continuous phrase taken directly from the passage or question. In such questions, the answer spans are recommended to be five words. Questions with answer type "number", are expected to start with "How many". For instance, "How long did an event last?" can be phrased as "How many years did an event last?". To increase diversity, try to create more questions for which the answer will be multiple spans. Please create questions that require AT LEAST 2 arithmetic operations as illustrated in the 'positive examples' field. You are encouraged to try DIFFERENT COMBINATIONS of operations and not just limit to the combinations shown in those examples. The more challenging questions you create, the better it is.
Passage: On 19 June 1911 the National Constitutional Assembly proclaimed A Portuguesa as the national anthem, replacing the old anthem Hymno da Carta in use since May 1834, and its status as national symbol was included in the new constitution. A Portuguesa was composed in 1890, with music by Alfredo Keil and lyrics by Henrique Lopes de Mendonca, in response to the 1890 British Ultimatum. Because of its patriotic character, it had been used, with slight modifications, by the rebels of the 1891 uprising in a failed attempt at a coup d'etat to establish a republic in Portugal, an event which caused the anthem to be forbidden by the monarchic authorities.
A:
A Portuguesa was proclaimed as the national anthem how many years after the song was composed?
