Problem: Prince Louis intended to land in the south of England in May 1216, and John assembled a naval force to intercept him. Unfortunately for John, his fleet was dispersed by bad storms and Louis landed unopposed in Kent. John hesitated and decided not to attack Louis immediately, either due to the risks of open battle or over concerns about the loyalty of his own men. Louis and the rebel barons advanced west and John retreated, spending the summer reorganising his defences across the rest of the kingdom. John saw several of his military household desert to the rebels, including his half-brother, William Longespée. By the end of the summer the rebels had regained the south-east of England and parts of the north.
When did the rebels regain the south-east of England?
---
Answer: end of the summer


Problem: During the September 11, 2001 attacks on the World Trade Center, FBI agent Leonard W. Hatton Jr. was killed during the rescue effort while helping the rescue personnel evacuate the occupants of the South Tower and stayed when it collapsed.

Problem: Anti-aircraft warfare or counter-air defence is defined by NATO as "all measures designed to nullify or reduce the effectiveness of hostile air action." They include ground-and air-based weapon systems, associated sensor systems, command and control arrangements and passive measures (e.g. barrage balloons). It may be used to protect naval, ground, and air forces in any location. However, for most countries the main effort has tended to be 'homeland defence'. NATO refers to airborne air defence as counter-air and naval air defence as anti-aircraft warfare. Missile defence is an extension of air defence as are initiatives to adapt air defence to the task of intercepting any projectile in flight.
What is the primary effort been for most countries when it comes to anti-aircraft warfare?

Answer:
homeland defence
