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.
Output: In what year did francis, duke of anjou leave the netherlands?
The generated question is perfect. Because the question is based on second sentence of the input passage and its answer is 1583.

New input case for you: Erythrasma is a skin infection which is caused by Corynebacterium minutissimum. Interdigital erythrasma is the most common form. The aim of this study was to detect the frequency and risk factors of interdigital erythrasma in patients with clinically suspected tinea pedis. This study was conducted between June and December 2010 and included 122 patients who had interdigital foot lesions. All patients were examined using a Wood's lamp. The smears were stained using Gram's method. Direct examination was performed using 20% potassium hydroxide. Sabouraud dextrose agar and brain heart infusion agar were used for cultures. Moreover, the demographical characteristics of patients, concomitant diseases and clinical findings were also recorded. Cases that were found to be positive on Wood's lamp examination and/or Gram staining/culture were considered as erythrasma. The rate of erythrasma was found to be 46.7%. The mean age was 43.6 years, and the disease was more prevalent in men. The most common clinical finding was desquamation. Mycological examination was found as positive in 40.35% of the patients. No growth was observed in bacteriological cultures. It was found that using only Wood's lamp examination or Gram staining resulted in 11 (9%) and 19 positive patients (15.6%), respectively, whereas using both Wood's lamp examination and Gram staining concurrently resulted in 27 positive patients (22.1%). Interdigital erythrasma is a commonly seen condition and can clinically mimic tinea pedis. A Wood's lamp is a good diagnostic tool, but Gram staining, particularly in those with a negative Wood's lamp result, may be a useful method.
Output:
Which bacteria causes erythrasma?
