Input: Anti-aircraft warfare
Another aspect of anti-aircraft defence was the use of barrage balloons to act as physical obstacle initially to bomber aircraft over cities and later for ground attack aircraft over the Normandy invasion fleets. The balloon, a simple blimp tethered to the ground, worked in two ways. Firstly, it and the steel cable were a danger to any aircraft that tried to fly among them. Secondly, to avoid the balloons, bombers had to fly at a higher altitude, which was more favorable for the guns. Barrage balloons were limited in application, and had minimal success at bringing down aircraft, being largely immobile and passive defences.

What were barrage balloons initially used as an obstacle to?
Output: bomber aircraft over cities

Input: Mexico City
Mexico City is located in the Valley of Mexico, sometimes called the Basin of Mexico. This valley is located in the Trans-Mexican Volcanic Belt in the high plateaus of south-central Mexico. It has a minimum altitude of 2,200 meters (7,200 feet) above sea level and is surrounded by mountains and volcanoes that reach elevations of over 5,000 metres (16,000 feet). This valley has no natural drainage outlet for the waters that flow from the mountainsides, making the city vulnerable to flooding. Drainage was engineered through the use of canals and tunnels starting in the 17th century.

How does the city prevent flooding?
Output: canals and tunnels

Input: Buddhism
According to author Michael Carrithers, while there are good reasons to doubt the traditional account, "the outline of the life must be true: birth, maturity, renunciation, search, awakening and liberation, teaching, death." In writing her biography of the Buddha, Karen Armstrong noted, "It is obviously difficult, therefore, to write a biography of the Buddha that meets modern criteria, because we have very little information that can be considered historically sound... [but] we can be reasonably confident Siddhatta Gotama did indeed exist and that his disciples preserved the memory of his life and teachings as well as they could."[dubious discuss]

What do some say is Buddha's real name?
Output: Siddhatta Gotama

Input: Antibiotics
Interactions between alcohol and certain antibiotics may occur and may cause side-effects and decreased effectiveness of antibiotic therapy. While moderate alcohol consumption is unlikely to interfere with many common antibiotics, there are specific types of antibiotics with which alcohol consumption may cause serious side-effects. Therefore, potential risks of side-effects and effectiveness depend on the type of antibiotic administered. Despite the lack of a categorical counterindication, the belief that alcohol and antibiotics should never be mixed is widespread.

What is one potential issue with drinking alcohol while taking antibiotics?
Output:
decreased effectiveness
