Q: In 1582 the united provinces invited francis, duke of anjou to lead them; but after a failed attempt to take antwerp in 1583, the duke left the netherlands again. after the assassination of william of orange (10 july 1584), both henry iii of france and elizabeth i of england declined the offer of sovereignty. however, the latter agreed to turn the united provinces into a protectorate of england (treaty of nonsuch, 1585), and sent the earl of leicester as governor-general. this was unsuccessful and in 1588 the provinces became a confederacy. the union of utrecht is regarded as the foundation of the republic of the seven united provinces, which was not recognized by the spanish empire until the peace of westphalia in 1648.
A: In what year did francis, duke of anjou leave the netherlands?
Rationale: The generated question is perfect. Because the question is based on second sentence of the input passage and its answer is 1583.
Q: _ (from How Do Animals Move?) Many animals scurry up tree trunks to escape enemies or find food. Some live in the treetops. Many of these animals are not only expert climbers, but they also have found interesting ways to get from tree to tree. How Do Animals Adapt?andHow Do Animals Move? are comprehensive explorations of animal adaptations and movement for young readers. Both are part of a 21 book series,The Science of Living Things. InHow Do Animals Adapt?readers learn how animals adapt to survive with respect not only to climate, darkness, food and defenses but also to offspring and people. These adaptations are well explained in double page spreads with examples clearly depicted in photographs and diagrams and developed through their accompanying captions . As the title suggests, movement is the focus ofHow Do Animals Move?Beginning with a description of the explanation of movement, the reader is exposed to the many different ways of animals movement in the air, on land, under ground and in the water. Several unconventional variations (e.g. looping of inchworms, the rectilinear motion of snakes) are included. Once again, the photographs and diagrams plainly support the double page spread discussions of animal movement. The language of both titles is simple enough for young readers without talking down to them. In both books, terminology is featured in . Some of these words are explained in the basic glossary while the majority are explained clearly in the text. Many of these terms provide readers with some fascinating, uncommon words (e.g. brachiation, potassium, skein, and estimate). As do many of Kalman's book, both of these titles have a table of contents, glossary and index which are all enough to introduce young readers to the nature of these tools. Both titles would make excellent additions to any science collection for young readers.
