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 is the second time period mentioned?, Context: European colonialism in the Sahara began in the 19th century. France conquered the regency of Algiers from the Ottomans in 1830, and French rule spread south from Algeria and eastwards from Senegal into the upper Niger to include present-day Algeria, Chad, Mali then French Sudan including Timbuktu, Mauritania, Morocco (1912), Niger, and Tunisia (1881). By the beginning of the 20th century, the trans-Saharan trade had clearly declined because goods were moved through more modern and efficient means, such as airplanes, rather than across the desert.
Example Output: 1830

Example Input: Who filed a lawsuit in the same month as Independence Day?, Context: Political interest groups have stated that these laws remove important restrictions on governmental authority, and are a dangerous encroachment on civil liberties, possible unconstitutional violations of the Fourth Amendment. On 30 July 2003, the American Civil Liberties Union (ACLU) filed the first legal challenge against Section 215 of the Patriot Act, claiming that it allows the FBI to violate a citizen's First Amendment rights, Fourth Amendment rights, and right to due process, by granting the government the right to search a person's business, bookstore, and library records in a terrorist investigation, without disclosing to the individual that records were being searched. Also, governing bodies in a number of communities have passed symbolic resolutions against the act.
Example Output: ACLU
