In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

Example Input: What has been a public health problem in developed countries in the past?, Context: The M. tuberculosis complex (MTBC) includes four other TB-causing mycobacteria: M. bovis, M. africanum, M. canetti, and M. microti. M. africanum is not widespread, but it is a significant cause of tuberculosis in parts of Africa. M. bovis was once a common cause of tuberculosis, but the introduction of pasteurized milk has almost completely eliminated this as a public health problem in developed countries. M. canetti is rare and seems to be limited to the Horn of Africa, although a few cases have been seen in African emigrants. M. microti is also rare and is seen almost only in immunodeficient people, although its prevalence may be significantly underestimated.
Example Output: tuberculosis

Example Input: What had kept egyptian citizens poor before Nasser?, Context: Nasser made Egypt fully independent of British influence, and the country became a major power in the developing world under his leadership. One of Nasser's main domestic efforts was to establish social justice, which he deemed a prerequisite to liberal democracy. During his presidency, ordinary citizens enjoyed unprecedented access to housing, education, jobs, health services and nourishment, as well as other forms of social welfare, while feudalistic influence waned. By the end of his presidency, employment and working conditions improved considerably, although poverty was still high in the country and substantial resources allocated for social welfare had been diverted to the war effort.

feudalistic influence
