Input: Daylight saving time
DST's clock shifts have the obvious disadvantage of complexity. People must remember to change their clocks; this can be time-consuming, particularly for mechanical clocks that cannot be moved backward safely. People who work across time zone boundaries need to keep track of multiple DST rules, as not all locations observe DST or observe it the same way. The length of the calendar day becomes variable; it is no longer always 24 hours. Disruption to meetings, travel, broadcasts, billing systems, and records management is common, and can be expensive. During an autumn transition from 02:00 to 01:00, a clock reads times from 01:00:00 through 01:59:59 twice, possibly leading to confusion.

What added complexity do people working across time zones have to keep track of?
Output: multiple DST rules

Input: Josip Broz Tito
His best known wife was Jovanka Broz. Tito was just shy of his 59th birthday, while she was 27, when they finally married in April 1952, with state security chief Aleksandar Ranković as the best man. Their eventual marriage came about somewhat unexpectedly since Tito actually rejected her some years earlier when his confidante Ivan Krajacic brought her in originally. At that time, she was in her early 20s and Tito, objecting to her energetic personality, opted for the more mature opera singer Zinka Kunc instead. Not one to be discouraged easily, Jovanka continued working at Beli Dvor, where she managed the staff and eventually got another chance after Tito's strange relationship with Zinka failed. Since Jovanka was the only female companion he married while in power, she also went down in history as Yugoslavia's first lady. Their relationship was not a happy one, however. It had gone through many, often public, ups and downs with episodes of infidelities and even allegations of preparation for a coup d'état by the latter pair. Certain unofficial reports suggest Tito and Jovanka even formally divorced in the late 1970s, shortly before his death. However, during Tito's funeral she was officially present as his wife, and later claimed rights for inheritance. The couple did not have any children.

Who went down in history as Yugoslavia's first lady?
Output: Jovanka

Input: Predation
Aposematism, where organisms are brightly colored as a warning to predators, is the antithesis of camouflage. Some organisms pose a threat to their predators—for example they may be poisonous, or able to harm them physically. Aposematic coloring involves bright, easily recognizable and unique colors and patterns. For example, bright coloration in Variable Checkerspot butterflies leads to decreased predation attempts by avian predators. Upon being harmed (e.g., stung) by their prey, the appearance in such an organism will be remembered as something to avoid. While that particular prey organism may be killed, the coloring benefits the prey species as a whole.

What scientific term is used to describe  organisms that are brightly colored as a warning to predators?
Output: Aposematism

Input: Red
Red is the traditional color of warning and danger. In the Middle Ages, a red flag announced that the defenders of a town or castle would fight to defend it, and a red flag hoisted by a warship meant they would show no mercy to their enemy. In Britain, in the early days of motoring, motor cars had to follow a man with a red flag who would warn horse-drawn vehicles, before the Locomotives on Highways Act 1896 abolished this law. In automobile races, the red flag is raised if there is danger to the drivers. In international football, a player who has made a serious violation of the rules is shown a red penalty card and ejected from the game.

Which British law forbade cars from following a bearer of a red flag as a warning to horse drawn vehicles?
Output:
the Locomotives on Highways Act 1896
