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 are the internal layer of pouches on an etioplast called?, Context: If angiosperm shoots are not exposed to the required light for chloroplast formation, proplastids may develop into an etioplast stage before becoming chloroplasts. An etioplast is a plastid that lacks chlorophyll, and has inner membrane invaginations that form a lattice of tubes in their stroma, called a prolamellar body. While etioplasts lack chlorophyll, they have a yellow chlorophyll precursor stocked. Within a few minutes of light exposure, the prolamellar body begins to reorganize into stacks of thylakoids, and chlorophyll starts to be produced. This process, where the etioplast becomes a chloroplast, takes several hours. Gymnosperms do not require light to form chloroplasts.
Example Output: invaginations

Example Input: How many secessionist states did not have a military governor?, Context: In 1864, Andrew Johnson (a War Democrat from Tennessee) was elected Vice President under Abraham Lincoln. He became President after Lincoln's assassination in 1865. Under Johnson's lenient re-admission policy, Tennessee was the first of the seceding states to have its elected members readmitted to the U.S. Congress, on July 24, 1866. Because Tennessee had ratified the Fourteenth Amendment, it was the only one of the formerly secessionist states that did not have a military governor during the Reconstruction period.
Example Output: one

Example Input: In 2013, what city hosted a Beyonce performance of a single song?, Context: In January 2013, Destiny's Child released Love Songs, a compilation album of the romance-themed songs from their previous albums and a newly recorded track, "Nuclear". Beyoncé performed the American national anthem singing along with a pre-recorded track at President Obama's second inauguration in Washington, D.C. The following month, Beyoncé performed at the Super Bowl XLVII halftime show, held at the Mercedes-Benz Superdome in New Orleans. The performance stands as the second most tweeted about moment in history at 268,000 tweets per minute. At the 55th Annual Grammy Awards, Beyoncé won for Best Traditional R&B Performance for "Love on Top". Her feature-length documentary film, Life Is But a Dream, first aired on HBO on February 16, 2013. The film, which she directed and produced herself, featured footage from her childhood, her as a mother and businesswoman, recording, rehearsing for live performances, and her return to the spotlight following Blue Ivy's birth. Its DVD release in November 2013 was accompanied by footage from the Revel Presents: Beyoncé Live concerts and a new song, "God Made You Beautiful". In February 2013, Beyoncé signed a global publishing agreement with Warner/Chappell Music, which would cover her future songwriting and then-upcoming studio album.
Example Output:
Washington, D.C
