He served an apprenticeship as an embroiderer and from 1896 to 1901 was employed as a master embroiderer, department head and warehouse director in lace and linen factories in Plauen, Herford and Köln. This was followed by military service from 1901-1903, after which he returned to employment in the Plauen Lace Factyory (Plauener Spitzenfabriken). He established his own lace factory, Mutschmann & Eisentraut, in Plauen in October 1907. During World War I, he served on the Western Front until he was severely wounded in April 1916. He was discharged from the Army as unfit for field service on 24 December 1916, then resuming the direction of his factory in Plauen. After the war, he was an early participant in the nationalist and anti-semitic Deutschvölkischer Schutz und Trutzbund. He was a founding member of the local branch (Ortsgruppe) of the National Socialist German Workers Party (NSDAP) in Plauen and made personal donations of capital to the Nazi Party.

PROBLEM: Passage: The cruiser Bayan (Russian: Баян) was the name ship of the four armoured cruisers built for the Imperial Russian Navy in the first decade of the 20th century. The ship had to be built in France because there was no available capacity in Russia. Bayan was assigned to the First Pacific Squadron after completion and based at Port Arthur from the end of 1903. She suffered minor damage during the Battle of Port Arthur at the beginning of the Russo-Japanese War of 1904–05 and supported destroyers as they patrolled outside the harbour. After bombarding Japanese positions in July 1904, the ship struck a mine and was out of action for the next several months. Bayan was sunk during the Siege of Port Arthur and was then salvaged by the Japanese after the war.

PROBLEM: Passage: Herpesviruses are a third group of common cancer-causing viruses. Two types of herpesviruses have been associated with cancer: the Epstein–Barr virus (EBV) and human herpesvirus 8 (HHV-8). EBV appears to cause all nonkeratinizing nasopharyngeal carcinomas and some cases of lymphoma, including Burkitt's lymphoma—the association is especially strong in Africa—and Hodgkin's disease. EBV has also been found in a variety of other types of cancer cells, although its role in causing these other cancers is not well established. KSHV/HHV-8 causes all cases of Kaposi's sarcoma, and has been found in some cases of a cancer-related condition called Castleman's disease. Studies involving other kinds of cancer, particularly prostate cancer, have been inconsistent. Both of these herpesviruses are commonly found in cancerous cells of primary effusion lymphoma. Herpesviruses also cause cancer in animals, especially leukemias and lymphomas.
