Question: The term "push-pull" was established in 1987 as an approach for integrated pest management (IPM). This strategy uses a mixture of behavior-modifying stimuli to manipulate the distribution and abundance of insects. "Push" means the insects are repelled or deterred away from whatever resource that is being protected. "Pull" means that certain stimuli (semiochemical stimuli, pheromones, food additives, visual stimuli, genetically altered plants, etc.) are used to attract pests to trap crops where they will be killed. There are numerous different components involved in order to implement a Push-Pull Strategy in IPM.

Question: Such strategies, which minimize the maximum loss for each player, are called optimal. Von Neumann showed that their minimaxes are equal (in absolute value) and contrary (in sign). Von Neumann improved and extended the minimax theorem to include games involving imperfect information and games with more than two players, publishing this result in his 1944 Theory of Games and Economic Behavior (written with Oskar Morgenstern). Morgenstern wrote a paper on game theory and thought he would show it to von Neumann because of his interest in the subject. He read it and said to Morgenstern that he should put more in it. This was repeated a couple of times, and then von Neumann became a coauthor and the paper became 100 pages long. Then it became a book. The public interest in this work was such that The New York Times ran a front-page story. In this book, von Neumann declared that economic theory needed to use functional analytic methods, especially convex sets and topological fixed-point theorem, rather than the traditional differential calculus, because the maximum-operator did not preserve differentiable functions.

Question: By the 12th century, Romanesque architecture (termed Norman architecture in England because of its association with the Norman invasion), was established throughout Europe and provided the basic architectural forms and units that were to remain in evolution throughout the Medieval period. The important categories of building: the cathedral church, the parish church, the monastery, the castle, the palace, the great hall, the gatehouse, the civic building, had been established in the Romanesque period.
Try to answer this question if possible: The Romanesque style continued to affect and inspire the basic architectural forms throughout which period?
Answer: the Medieval period
Question: On 19 November 1968, following progressive economic decline, the Keita regime was overthrown in a bloodless military coup led by Moussa Traore, a day which is now commemorated as Liberation Day. The subsequent military-led regime, with Traore as president, attempted to reform the economy. His efforts were frustrated by political turmoil and a devastating drought between 1968 to 1974, in which famine killed thousands of people. The Traore regime faced student unrest beginning in the late 1970s and three coup attempts. The Traore regime repressed all dissenters until the late 1980s.
