Definition: 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.
Input: Passage: Odes 1-3 were the next focus for his artistic creativity. He adapted their forms and themes from Greek lyric poetry of the seventh and sixth centuries BC. The fragmented nature of the Greek world had enabled his literary heroes to express themselves freely and his semi-retirement from the Treasury in Rome to Horaces Villa in the Sabine hills perhaps empowered him to some extent also yet even when his lyrics touched on public affairs they reinforced the importance of private life. Nevertheless, his work in the period 30-27 BC began to show his closeness to the regime and his sensitivity to its developing ideology. In Odes 1.2, for example, he eulogized Octavian in hyperboles that echo Hellenistic court poetry. The name Augustus, which Octavian assumed in January 27 BC, is first attested in Odes 3.3 and 3.5. In the period 27-24 BC, political allusions in the Odes concentrated on foreign wars in Britain (1.35), Arabia (1.29) Spain (3.8) and Parthia (2.2). He greeted Augustus on his return to Rome in 24 BC as a beloved ruler upon whose good health he depended for his own happiness (3.14).
Output:
How many years was the period where his work showed his closeness to the regime and sensitivity to its developing ideology?
