Problem: Another deck structure that can be seen is a ski-jump ramp at the forward end of the flight deck. This was first developed to help launch STOVL aircraft take off at far higher weights than is possible with a vertical or rolling takeoff on flat decks. Originally developed by the Royal Navy, it since has been adopted by many navies for smaller carriers. A ski-jump ramp works by converting some of the forward rolling movement of the aircraft into vertical velocity and is sometimes combined with the aiming of jet thrust partly downwards. This allows heavily loaded and fueled aircraft a few more precious seconds to attain sufficient air velocity and lift to sustain normal flight. Without a ski-jump launching fully loaded and fueled aircraft such as the Harrier would not be possible on a smaller flat deck ship before either stalling out or crashing directly into the sea.
What does the ski-jump ramp prevent a fully loaded and fueled aircraft from doing?
The answer is the following: either stalling out or crashing directly into the sea

Problem: The Siddi are an ethnic group inhabiting India and Pakistan whose members are descended from Bantu peoples from Southeast Africa that were brought to the Indian subcontinent as slaves by Arab and Portuguese merchants. Although it is commonly believed locally that "Siddi" derives from a word meaning "black", the term is actually derived from "Sayyid", the title borne by the captains of the Arab vessels that first brought Siddi settlers to the area. In the Makran strip of the Sindh and Balochistan provinces in southwestern Pakistan, these Bantu descendants are known as the Makrani. There was a brief "Black Power" movement in Sindh in the 1960s and many Siddi are proud of and celebrate their African ancestry.
When was the "black power" movement in Sindh?
The answer is the following: 1960s

Problem: The secondary and high school education system in Swaziland is a five-year programme divided into three years junior secondary and two years senior secondary. There is an external public examination (Junior Certificate) at the end of the junior secondary that learners have to pass to progress to the senior secondary level. The Examination Council of Swaziland (ECOS) administers this examination. At the end of the senior secondary level, learners sit for a public examination, the Swaziland General Certificate of Secondary Education (SGCSE) and International General Certificate of Secondary Education (IGCSE) which is accredited by the Cambridge International Examination (CIE). A few schools offer the Advanced Studies (AS) programme in their curriculum.
How many years does a student spend in secondary and high school in Swaziland?
The answer is the following: five

Problem: There is ongoing debate about whether central banks should target zero inflation (which would mean a constant value for the U.S. dollar over time) or low, stable inflation (which would mean a continuously but slowly declining value of the dollar over time, as is the case now). Although some economists are in favor of a zero inflation policy and therefore a constant value for the U.S. dollar, others contend that such a policy limits the ability of the central bank to control interest rates and stimulate the economy when needed.
With a zero inflation rate, what would the central bank be unable to do other than control interest rates?
The answer is the following:
stimulate the economy
