Problem: Anti-aircraft warfare:

The first issue was ammunition. Before the war it was recognised that ammunition needed to explode in the air. Both high explosive (HE) and shrapnel were used, mostly the former. Airburst fuses were either igniferious (based on a burning fuse) or mechanical (clockwork). Igniferious fuses were not well suited for anti-aircraft use. The fuse length was determined by time of flight, but the burning rate of the gunpowder was affected by altitude. The British pom-poms had only contact-fused ammunition. Zeppelins, being hydrogen filled balloons, were targets for incendiary shells and the British introduced these with airburst fuses, both shrapnel type-forward projection of incendiary 'pot' and base ejection of an incendiary stream. The British also fitted tracers to their shells for use at night. Smoke shells were also available for some AA guns, these bursts were used as targets during training.

It was understood that ammunition needed to explode where?

A: in the air

Problem: Other cities with a concentration of secular Gothic include Bruges and Siena. Most surviving small secular buildings are relatively plain and straightforward; most windows are flat-topped with mullions, with pointed arches and vaulted ceilings often only found at a few focal points. The country-houses of the nobility were slow to abandon the appearance of being a castle, even in parts of Europe, like England, where defence had ceased to be a real concern. The living and working parts of many monastic buildings survive, for example at Mont Saint-Michel.
What is the only city with an accumulation of secular Gothic structures?

Context and question: In Thailand, a kingdom that has had a constitution since the initial attempt to overthrow the absolute monarchy system in 1932, the rule of law has been more of a principle than actual practice.[citation needed] Ancient prejudices and political bias have been present in the three branches of government with each of their foundings, and justice has been processed formally according to the law but in fact more closely aligned with royalist principles that are still advocated in the 21st century.[citation needed] In November 2013, Thailand faced still further threats to the rule of law when the executive branch rejected a supreme court decision over how to select senators.[citation needed]
What has been practiced in Thailand since 1932?
Answer: unanswerable

Question: Walt Disney Parks and Resorts plans on creating original Marvel attractions at their theme parks, with Hong Kong Disneyland becoming the first Disney theme park to feature a Marvel attraction. Due to the licensing agreement with Universal Studios, signed prior to Disney's purchase of Marvel, Walt Disney World and Tokyo Disney are barred from having Marvel characters in their parks. However, this only includes characters Universal is currently using, other characters in their "families" (X-Men, Avengers, Fantastic Four, etc.), and the villains associated with said characters. This clause has allowed Walt Disney World to have meet and greets, merchandise, attractions and more with other Marvel characters not associated with the characters at Islands of Adventures, such as Star-Lord and Gamora from Guardians of the Galaxy as well as Baymax and Hiro from Big Hero 6.
Is there an answer to this question: What was signed after Disney purchased Marvel?
