Article: 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.

Question: During the fall time shift from 02:00 to 01:00, how many times will a clock show the times between 01:00:00 and 01:59:59?
Ans: twice

Article: Some symbiotic relationships are obligate, meaning that both symbionts entirely depend on each other for survival. For example, many lichens consist of fungal and photosynthetic symbionts that cannot live on their own. Others are facultative (optional): they can, but do not have to live with the other organism.

Question: What is the type of symbiotic relationship where the symbionts can live together but can also survive alone?
Ans: facultative

Article: The Guangxu Emperor died on November 14, 1908, and on November 15, 1908, Cixi also died. Rumors held that she or Yuan Shikai ordered trusted eunuchs to poison the Guangxu Emperor, and an autopsy conducted nearly a century later confirmed lethal levels of arsenic in his corpse. Puyi, the oldest son of Zaifeng, Prince Chun, and nephew to the childless Guangxu Emperor, was appointed successor at the age of two, leaving Zaifeng with the regency. This was followed by the dismissal of General Yuan Shikai from his former positions of power. In April 1911 Zaifeng created a cabinet in which there were two vice-premiers. Nonetheless, this cabinet was also known by contemporaries as "The Royal Cabinet" because among the thirteen cabinet members, five were members of the imperial family or Aisin Gioro relatives. This brought a wide range of negative opinions from senior officials like Zhang Zhidong. The Wuchang Uprising of October 10, 1911, led to the creation of a new central government, the Republic of China, in Nanjing with Sun Yat-sen as its provisional head. Many provinces soon began "separating" from Qing control. Seeing a desperate situation unfold, the Qing government brought Yuan Shikai back to military power. He took control of his Beiyang Army to crush the revolution in Wuhan at the Battle of Yangxia. After taking the position of Prime Minister and creating his own cabinet, Yuan Shikai went as far as to ask for the removal of Zaifeng from the regency. This removal later proceeded with directions from Empress Dowager Longyu.

Question: Who ruled after Guangxu?
Ans: Prince Chun

The Oklahoma judiciary also contains two independent courts: a Court of Impeachment and the Oklahoma Court on the Judiciary. Oklahoma has two courts of last resort: the state Supreme Court hears civil cases, and the state Court of Criminal Appeals hears criminal cases (this split system exists only in Oklahoma and neighboring Texas). Judges of those two courts, as well as the Court of Civil Appeals are appointed by the Governor upon the recommendation of the state Judicial Nominating Commission, and are subject to a non-partisan retention vote on a six-year rotating schedule.
