Problem: Aircraft carrier:

The disadvantage of the ski-jump is the penalty it exacts on aircraft size, payload, and fuel load (and thus range); heavily laden aircraft can not launch using a ski-jump because their high loaded weight requires either a longer takeoff roll than is possible on a carrier deck, or assistance from a catapult or JATO rocket. For example, the Russian Su-33 is only able to launch from the carrier Admiral Kuznetsov with a minimal armament and fuel load. Another disadvantage is on mixed flight deck operations where helicopters are also present such as a US Landing Helicopter Dock or Landing Helicopter Assault amphibious assault ship a ski jump is not included as this would eliminate one or more helicopter landing areas, this flat deck limits the loading of Harriers but is somewhat mitigated by the longer rolling start provided by a long flight deck compared to many STOVL carriers.

What do heavily laden aircraft sometimes require the assistance from?
---
A: a catapult or JATO rocket

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
According to Archibald Sayce, the primitive pictograms of the early Sumerian (i.e. Uruk) era suggest that "Stone was scarce, but was already cut into blocks and seals. Brick was the ordinary building material, and with it cities, forts, temples and houses were constructed. The city was provided with towers and stood on an artificial platform; the house also had a tower-like appearance. It was provided with a door which turned on a hinge, and could be opened with a sort of key; the city gate was on a larger scale, and seems to have been double. The foundation stones or rather bricks of a house were consecrated by certain objects that were deposited under them."
What were the foundation stones of Sumerian houses consecrated by?
A: objects that were deposited under them

Context and question: The military history of the American side of the war involved different strategies over the years. The bombing campaigns of the Air Force were tightly controlled by the White House for political reasons, and until 1972 avoided the main Northern cities of Hanoi and Haiphong and concentrated on bombing jungle supply trails, especially the Ho Chi Minh Trail. The most controversial Army commander was William Westmoreland whose strategy involved systematic defeat of all enemy forces in the field, despite heavy American casualties that alienated public opinion back home.
What two northern Vietnamese cities did the US avoid bombing at the outset of the war?
Answer: Hanoi and Haiphong

Question: As of the first decade of the 21st century, contemporary neoclassical architecture is usually classed under the umbrella term of New Classical Architecture. Sometimes it is also referred to as Neo-Historicism/Revivalism, Traditionalism or simply neoclassical architecture like the historical style. For sincere traditional-style architecture that sticks to regional architecture, materials and craftsmanship, the term Traditional Architecture (or vernacular) is mostly used. The Driehaus Architecture Prize is awarded to major contributors in the field of 21st century traditional or classical architecture, and comes with a prize money twice as high as that of the modernist Pritzker Prize.
Is there an answer to this question: What is awarded to architects who contribute to 21st-century classical architecture?

Answer: unanswerable

QUES: From 1721 this was the Whig politician Robert Walpole, who held office for twenty-one years. Walpole chaired cabinet meetings, appointed all the other ministers, dispensed the royal patronage and packed the House of Commons with his supporters. Under Walpole, the doctrine of cabinet solidarity developed. Walpole required that no minister other than himself have private dealings with the king, and also that when the cabinet had agreed on a policy, all ministers must defend it in public, or resign. As a later prime minister, Lord Melbourne, said, "It matters not what we say, gentlemen, so long as we all say the same thing."

What concept took shape during Walpole's tenure as prime minister?
What is the answer?
ANS:
doctrine of cabinet solidarity
