This task involves creating answers to complex questions, from a given passage. Answering these questions, typically involve understanding multiple sentences. Make sure that your answer has the same type as the "answer type" mentioned in input. The provided "answer type" can be of any of the following types: "span", "date", "number". A "span" answer is a continuous phrase taken directly from the passage or question. You can directly copy-paste the text from the passage or the question for span type answers. If you find multiple spans, please add them all as a comma separated list. Please restrict each span to five words. A "number" type answer can include a digit specifying an actual value. For "date" type answers, use DD MM YYYY format e.g. 11 Jan 1992. If full date is not available in the passage you can write partial date such as 1992 or Jan 1992. If you find multiple spans, please add them all as a comma separated list. Please restrict each span to five words.

Let me give you an example: Passage: The outbreak of the Seven Years' War in Europe in 1756 resulted in renewed conflict between French and British forces in India. The Third Carnatic War spread beyond southern India and into Bengal where British forces captured the French settlement of Chandernagore in 1757. However, the war was decided in the south, where the British successfully defended Madras, and Sir Eyre Coote decisively defeated the French, commanded by Comte de Lally at the Battle of Wandiwash in 1760. After Wandiwash, the French capital of Pondicherry fell to the British in 1761. The war concluded with the signing of the Treaty of Paris in 1763, which returned Chandernagore and Pondichery to France, and allowed the French to have "factories" in India but forbade French traders from administering them. The French agreed to support British client governments, thus ending French ambitions of an Indian empire and making the British the dominant foreign power in India.
Question: Which french settlement did the British capture first, Chandernagore or Pondicherry
Answer type: Span
The answer to this example can be: Chandernagore
Here is why: British captured Chandernagore in 1757 ("The Third Carnatic War spread beyond southern India and into Bengal where British forces captured the French settlement of Chandernagore in 1757") and Pondicherry in 1761 ("After Wandiwash, the French capital of Pondicherry fell to the British in 1761."). Since 1757<1761, the answer is "Chandernagore".

OK. solve this:
Passage: While The Oxford Encyclopedia of British Literature states that modernism ended by c. 1939 with regard to British and American literature, "When (if) Modernism petered out and postmodernism began has been contested almost as hotly as when the transition from Victorianism to Modernism occurred." Clement Greenberg sees modernism ending in the 1930s, with the exception of the visual and performing arts, but with regard to music, Paul Griffiths (writer) notes that, while Modernism "seemed to be a spent force" by the late 1920s, after World War II, "a new generation of composers-Pierre Boulez, Jean Barraque, Milton Babbitt, Luigi Nono, Karlheinz Stockhausen, Iannis Xenakis" revived modernism". In fact many literary Modernists lived into the 1950s and 1960s, though generally they were no longer producing major works. The term "late modernism" is also sometimes applied to Modernist works published after 1930. Among Modernists (or late Modernists) still publishing after 1945 were Wallace Stevens, Gottfried Benn, T. S. Eliot, Anna Akhmatova, William Faulkner, Dorothy Richardson, John Cowper Powys, and Ezra Pound. Basil Bunting, born in 1901, published his most important Modernist poem Briggflatts in 1965. In addition, Hermann Brochs The Death of Virgil was published in 1945 and Thomas Manns Doctor Faustus (novel) in 1947. Samuel Beckett, who died in 1989, has been described as a "later Modernist". Beckett is a writer with roots in the expressionist tradition of Modernism, who produced works from the 1930s until the 1980s, including Molloy (novel) (1951), Waiting for Godot (1953), Happy Days (play) (1961), and Rockaby (1981). The terms "minimalist" and "post-Modernist" have also been applied to his later works. The poets Charles Olson (1910-1970) and J. H. Prynne (born 1936) are among the writers in the second half of the 20th century who have been described as late Modernists.
Question: How many years after producing Waiting for Godot did Beckett produce Rockaby?.?
