Teacher: Given a context passage, generate a question from the passage such that its answer is shortest continous span from the passage.
Teacher: Now, understand the problem? If you are still confused, see the following example:
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.
Solution: In what year did francis, duke of anjou leave the netherlands?
Reason: The generated question is perfect. Because the question is based on second sentence of the input passage and its answer is 1583.

Now, solve this instance: Ehlers-Danlos syndrome is a heterogeneous group of heritable connective tissue disorders characterized by increased fragility of various non-ossified tissues. It is usually ascertained due to abnormal skin texture, scarring complications, vascular fragility, or chronic symptoms, such as fatigue and musculoskeletal pain. Sometimes, Ehlers-Danlos syndrome remains undetected until the patient, usually in the pediatric age, shows extensive or severe mucocutaneous injuries after only minor traumas. In this scenario, the misdiagnosis of Ehlers-Danlos syndrome with child abuse is a possibility, as occasionally reported in the literature. Recently, more attention was posed by lay people between the possible association of Ehlers-Danlos syndrome and bone fragility. Literature and personal experience show a strong association between Ehlers-Danlos syndrome, generalized joint hypermobility and reduced bone mass density in older children and adults, especially fertile women. The existence of a true increased risk of fracture in Ehlers-Danlos syndrome is still a matter of debate in children and adults with little and conflicting evidence. In case of suspected child abuse, Ehlers-Danlos syndrome is certainly on the differential for bruising, especially in EDS types with marked cutaneous and capillary involvement. In suspected child abuse cases, careful examination of the index case and her/his extended family is routine, as well as exclusion of other disorders such as osteogenesis imperfecta. The hypothesis of Ehlers-Danlos syndrome as an alternative explanation for infantile fractures remains speculative.
