Problem: YouTube:

YouTube relies on its users to flag the content of videos as inappropriate, and a YouTube employee will view a flagged video to determine whether it violates the site's terms of service. In July 2008, the Culture and Media Committee of the House of Commons of the United Kingdom stated that it was "unimpressed" with YouTube's system for policing its videos, and argued that "proactive review of content should be standard practice for sites hosting user-generated content". YouTube responded by stating:

What do uses rely on YouTube to flag?

Problem: CNET awarded PS3 Slim four out of five stars praising its Blu-ray capabilities, 120 GB hard drive, free online gaming service and more affordable pricing point, but complained about the lack of backward compatibility for PlayStation 2 games. TechRadar gave PS3 Slim four and a half stars out of five praising its new smaller size and summed up its review stating "Over all, the PS3 Slim is a phenomenal piece of kit. It's amazing that something so small can do so much". However, they criticized the exterior design and the build quality in relation to the original model.
What area of the console did TechRadar feel was designed poorly compared to the original PS3?

Answer: exterior

Relations between Grand Lodges are determined by the concept of Recognition. Each Grand Lodge maintains a list of other Grand Lodges that it recognises. When two Grand Lodges recognise and are in Masonic communication with each other, they are said to be in amity, and the brethren of each may visit each other's Lodges and interact Masonically. When two Grand Lodges are not in amity, inter-visitation is not allowed. There are many reasons why one Grand Lodge will withhold or withdraw recognition from another, but the two most common are Exclusive Jurisdiction and Regularity.
What is not allowed when Grand Lodges are not in amity? 
A: inter-visitation


Context and question: Unwilling to accept and license Columbia's system, in February 1949 RCA Victor, in cooperation of its parent, the Radio Corporation of America, released the first 45 rpm single, 7 inches in diameter with a large center hole. The 45 rpm player included a changing mechanism that allowed multiple disks to be stacked, much as a conventional changer handled 78s. The short playing time of a single 45 rpm side meant that long works, such as symphonies, had to be released on multiple 45s instead of a single LP, but RCA claimed that the new high-speed changer rendered side breaks so brief as to be inaudible or inconsequential. Early 45 rpm records were made from either vinyl or polystyrene. They had a playing time of eight minutes.
What did RCA release to complete against Columbia's LP?
Answer: The 45 rpm player


Question: Hyderabad emerged as the foremost centre of culture in India with the decline of the Mughal Empire. After the fall of Delhi in 1857, the migration of performing artists to the city particularly from the north and west of the Indian sub continent, under the patronage of the Nizam, enriched the cultural milieu. This migration resulted in a mingling of North and South Indian languages, cultures and religions, which has since led to a co-existence of Hindu and Muslim traditions, for which the city has become noted.:viii A further consequence of this north–south mix is that both Telugu and Urdu are official languages of Telangana. The mixing of religions has also resulted in many festivals being celebrated in Hyderabad such as Ganesh Chaturthi, Diwali and Bonalu of Hindu tradition and Eid ul-Fitr and Eid al-Adha by Muslims.
Is there an answer to this question: What major event in India in 1857 caused migration of peformance artists into Hyderabad?

Answer: the fall of Delhi


Witherspoon et al. (2007) have argued that even when individuals can be reliably assigned to specific population groups, it may still be possible for two randomly chosen individuals from different populations/clusters to be more similar to each other than to a randomly chosen member of their own cluster. They found that many thousands of genetic markers had to be used in order for the answer to the question "How often is a pair of individuals from one population genetically more dissimilar than two individuals chosen from two different populations?" to be "never". This assumed three population groups separated by large geographic ranges (European, African and East Asian). The entire world population is much more complex and studying an increasing number of groups would require an increasing number of markers for the same answer. The authors conclude that "caution should be used when using geographic or genetic ancestry to make inferences about individual phenotypes." Witherspoon, et al. concluded that, "The fact that, given enough genetic data, individuals can be correctly assigned to their populations of origin is compatible with the observation that most human genetic variation is found within populations, not between them. It is also compatible with our ﬁnding that, even when the most distinct populations are considered and hundreds of loci are used, individuals are frequently more similar to members of other populations than to members of their own population."
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): People are more frequently similar to members of what populations?
Ah, so..
other populations
