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: This report describes the reliability, validity, treatment sensitivity, diagnostic performance and normative values for the Short Post-Traumatic Stress Disorder (PTSD) Rating Interview (SPRINT), a brief, global assessment for PTSD. The SPRINT was administered to subjects participating in a clinical trial of PTSD and in a population survey assessing PTSD prevalence. The 8-item SPRINT includes questions assessing the core symptoms of PTSD, as well as related aspects of somatic malaise, stress vulnerability and functional impairment. Validity was assessed against the MINI structured interview, the Davidson Trauma Scale, Treatment Outcome for PTSD Scale, Connor-Davidson Resilience Scale, Sheehan Stress Vulnerability Scale, Sheehan Disability Scale and Clinical Global Impressions of Severity and Improvement Scales. Good test-retest reliability, internal consistency, convergent and divergent validity were obtained. The SPRINT was responsive to symptom change over time and correlated with comparable PTSD symptom measures. In victims of trauma, a score of 14-17 was associated with 96% diagnostic accuracy, whereas in those with PTSD, highest efficiency corresponded to a range of 11-13. The SPRINT demonstrates solid psychometric properties and can serve as a reliable, valid and homogeneous measure of PTSD illness severity and of global improvement.
