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

Q: 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.

A: invaginations

Q: It can be inferred that what property of the island was strongly impacted by the fire that destroyed the fishing factory?, Context: On 13 February 2008, fire destroyed the fishing factory and the four generators that supplied power to the island. On 14 March 2008, new generators were installed and uninterrupted power was restored. This fire was devastating to the island because fishing is a mainstay of the economy. While a new factory was being planned and built, M/V Kelso came to the island and acted as a factory ship, with island fishermen based on board for stints normally of one week. The new facility was ready in July 2009, for the start of the 2009–10 fishing season.

A: economy

Q: What caused passage to not be permitted to the mentioned destination?, Context: The Exeter to Plymouth railway of the LSWR needs to be reopened to connect Cornwall and Plymouth to the rest of the UK railway system on an all weather basis. There are proposals to reopen the line from Tavistock to Bere Alston for a through service to Plymouth. On the night of 4 February 2014, amid high winds and extremely rough seas, part of the sea wall at Dawlish was breached washing away around 40 metres (130 ft) of the wall and the ballast under the railway immediately behind. The line was closed. Network Rail began repair work  and the line reopened on 4 April 2014. In the wake of widespread disruption caused by damage to the mainline track at Dawlish by coastal storms in February 2014, Network Rail are considering reopening the Tavistock to Okehampton and Exeter section of the line as an alternative to the coastal route.

A:
high winds and extremely rough seas
