Input: Article: The company, which benefited from the imperial patronage, soon expanded its commercial trading operations, eclipsing the Portuguese Estado da Índia, which had established bases in Goa, Chittagong, and Bombay, which Portugal later ceded to England as part of the dowry of Catherine de Braganza. The East India Company also launched a joint attack with the Dutch United East India Company on Portuguese and Spanish ships off the coast of China, which helped secure their ports in China. The company established trading posts in Surat (1619), Madras (1639), Bombay (1668), and Calcutta (1690). By 1647, the company had 23 factories, each under the command of a factor or master merchant and governor if so chosen, and 90 employees in India. The major factories became the walled forts of Fort William in Bengal, Fort St George in Madras, and Bombay Castle.

Now answer this question: when was the bombay trading post established?

Output: 1668

Input: Article: Maximilian was deeply dissatisfied with General Bazaine's decision to abandon the state capital of Chihuahua and immediately ordered Agustín B. Billaut to recapture the city. On December 11, 1865, Billaut with a force of 500 men took control of the city. By January 31, 1866 Billaut was ordered to leave Chihuahua, but he left behind 500 men to maintain control. At the zenith of their power, the imperialist forces controlled all but four states in Mexico; the only states to maintain strong opposition to the French were: Guerrero, Chihuahua, Sonora, and Baja California.

Now answer this question: At its zenith, the imperialist forces controlled all but how many states in Mexico?

Output: four

Input: Article: In the absence of suitable plate culture techniques, some microbes require culture within live animals. Bacteria such as Mycobacterium leprae and Treponema pallidum can be grown in animals, although serological and microscopic techniques make the use of live animals unnecessary. Viruses are also usually identified using alternatives to growth in culture or animals. Some viruses may be grown in embryonated eggs. Another useful identification method is Xenodiagnosis, or the use of a vector to support the growth of an infectious agent. Chagas disease is the most significant example, because it is difficult to directly demonstrate the presence of the causative agent, Trypanosoma cruzi in a patient, which therefore makes it difficult to definitively make a diagnosis. In this case, xenodiagnosis involves the use of the vector of the Chagas agent T. cruzi, an uninfected triatomine bug, which takes a blood meal from a person suspected of having been infected. The bug is later inspected for growth of T. cruzi within its gut.

Now answer this question: What is Xenodiagnosis?

Output:
use of a vector to support the growth of an infectious agent
