Article: In late 1975, Queen recorded and released A Night at the Opera, taking its name from the popular Marx Brothers movie. At the time, it was the most expensive album ever produced. Like its predecessor, the album features diverse musical styles and experimentation with stereo sound. In "The Prophet's Song", an eight-minute epic, the middle section is a canon, with simple phrases layered to create a full-choral sound. The Mercury penned ballad, "Love of My Life", featured a harp and overdubbed vocal harmonies. The album was very successful in Britain, and went triple platinum in the United States. The British public voted it the 13th greatest album of all time in a 2004 Channel 4 poll. It has also ranked highly in international polls; in a worldwide Guinness poll, it was voted the 19th greatest of all time, while an ABC poll saw the Australian public vote it the 28th greatest of all time. A Night at the Opera has frequently appeared in "greatest albums" lists reflecting the opinions of critics. Among other accolades, it was ranked number 16 in Q Magazine's "The 50 Best British Albums Ever" in 2004, and number 11 in Rolling Stone's "The 100 Greatest Albums of All Time" as featured in their Mexican edition in 2004. It was also placed at No. 230 on Rolling Stone magazine's list of "The 500 Greatest Albums of All Time" in 2003. A Night at the Opera is the third and final Queen album to be featured in the book 1001 Albums You Must Hear Before You Die.

The problem: Answer a question about this article:
The state united behind the Plan of Ayutla and ratified the new constitution in 1855. The state was able to survive through the Reform War with minimal damage due to the large number of liberal political figures. The 1858 conservative movement did not succeed in the state even after the successful military campaign of the conservative Zuloaga with 1,000 men occupied the cities of Chihuahua and Parral. In August 1859, Zuloaga and his forces were defeated by the liberal Orozco and his forces; Orozco soon after deposed the state governor, but had to flee to Durango two months later. In the late 1860s the conservative General Cajen briefly entered the state after his campaign through the state of Jalisco and helped establish conservative politicians and ran out the liberal leaders Jesus Gonzalez Ortega and Jose Maria Patoni. Cajen took possession of the state capital and established himself as governor; he brooked no delay in uniting a large force to combat the liberal forces which he defeated in La Batalla del Gallo. Cajen attained several advantages over the liberals within the state, but soon lost his standing due to a strong resurgence of the liberal forces within the state. The successful liberal leaders Jose Maria Patoni of Durango and J.E. Munoz of Chihuahua quickly strengthened their standing by limiting the political rights of the clergy implementing the presidential decree. The state elected General Luis Terrazas, a liberal leader, as governor; he would continue to fight small battles within the state to suppress conservative uprisings during 1861.
In which year was the new constitution ratified?
****
The answer: 1855

Within computer systems, two of many security models capable of enforcing privilege separation are access control lists (ACLs) and capability-based security. Using ACLs to confine programs has been proven to be insecure in many situations, such as if the host computer can be tricked into indirectly allowing restricted file access, an issue known as the confused deputy problem. It has also been shown that the promise of ACLs of giving access to an object to only one person can never be guaranteed in practice. Both of these problems are resolved by capabilities. This does not mean practical flaws exist in all ACL-based systems, but only that the designers of certain utilities must take responsibility to ensure that they do not introduce flaws.[citation needed]

A host computer tricked into indirectly allowing access to restricted files is known as what?
Answer: the confused deputy problem

By the time of the Uruk period (c. 41002900 BC calibrated), the volume of trade goods transported along the canals and rivers of southern Mesopotamia facilitated the rise of many large, stratified, temple-centered cities (with populations of over 10,000 people) where centralized administrations employed specialized workers. It is fairly certain that it was during the Uruk period that Sumerian cities began to make use of slave labor captured from the hill country, and there is ample evidence for captured slaves as workers in the earliest texts. Artifacts, and even colonies of this Uruk civilization have been found over a wide areafrom the Taurus Mountains in Turkey, to the Mediterranean Sea in the west, and as far east as central Iran.
During which period did Sumerian cities begin using slave labor?
Uruk
