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

Input: Consider 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.

Output: invaginations


Input: Consider Input: In what year did the second presidential debate occur at Washington University Athletic Complex?, Context: Washington University has been selected by the Commission on Presidential Debates to host more presidential and vice-presidential debates than any other institution in history. United States presidential election debates were held at the Washington University Athletic Complex in 1992, 2000, 2004, and 2016. A presidential debate was planned to occur in 1996, but owing to scheduling difficulties between the candidates, the debate was canceled. The university hosted the only 2008 vice presidential debate, between Republican Sarah Palin and Democrat Joe Biden, on October 2, 2008, also at the Washington University Athletic Complex.

Output: 2000


Input: Consider Input: What is needed to gain strength?, Context: The Armed Forces are today funded by approximately $20.1 billion annually and are presently ranked 74th in size compared to the world's other armed forces by number of total personnel, and 58th in terms of active personnel, standing at a strength of roughly 68,000, plus 27,000 reservists, 5000 Rangers, and 19,000 supplementary reserves, bringing the total force to approximately 119,000. The number of primary reserve personnel is expected to go up to 30,000 by 2020, and the number of active to at least 70,000. In addition, 5000 rangers and 19,000 supplementary personnel will be serving. If this happens the total strength would be around 124,000. These individuals serve on numerous CF bases located in all regions of the country, and are governed by the Queen's Regulations and Orders and the National Defence Act.


Output: The number of primary reserve personnel is expected to go up
