Given a context passage, generate a question from the passage such that its answer is shortest continous span from the passage.

Let me give you an 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.
The answer to this example can be: In what year did francis, duke of anjou leave the netherlands?
Here is why: The generated question is perfect. Because the question is based on second sentence of the input passage and its answer is 1583.

OK. solve this:
de Quervain's disease is an inadequacy into the first extensor compartment of wrist between the osteofibrous tunnel and the tendons. This mechanical conflict generates a tenosynovitis of the extensor pollicis brevis and the abductor pollicis longus tendons in first dorsal extensor compartment of the wrist. (1) To compare the clinical results obtained by longitudinal and transverse incisions and (2) the implication of clinical results in Indian population. This study was conducted at Kalpana Chawla Government Medical College, Karnal, Haryana. The inclusion criteria were positive Finkelstein's test and no response to non-surgical treatment for 6 weeks. Forty-eight patients with de Quervain's disease who did not respond to conservative treatment were operated with two different incisions. The patients were followed at 6 weeks, 3 and 6 months to compare the surgical outcomes. During a three-month follow-up, a significant difference was shown between the two methods (p = 0.0001). Results of surgical treatment with longitudinal incision were better (only one hypertrophic scar), but there were 12 postoperative complications with transverse incision. Visual analog scale (VAS) was used to evaluate the hypertrophic scar. In transverse incision group, out of five patients, four patients who developed hypertrophic scar have poor score according to VAS. Overall, longitudinal incision should be used for surgical treatment for de Quervain's disease due to lower risk of complications.
Answer:
Which disease is diagnosed using the Finkelstein's test?
