Please answer this: Question: "Why are you tube users upset?"  Context: "On November 6, 2013, Google implemented a new comment system that requires all YouTube users to use a Google+ account in order to comment on videos and making the comment system Google+ oriented. The changes are in large part an attempt to address the frequent criticisms of the quality and tone of YouTube comments. They give creators more power to moderate and block comments, and add new sorting mechanisms to ensure that better, more relevant discussions appear at the top. The new system restored the ability to include URLs in comments, which had previously been removed due to problems with abuse. In response, YouTube co-founder Jawed Karim posted the question "why the fuck do I need a google+ account to comment on a video?" on his YouTube channel to express his negative opinion of the change. The official YouTube announcement received 20,097 "thumbs down" votes and generated more than 32,000 comments in two days. Writing in the Newsday blog Silicon Island, Chase Melvin noted that "Google+ is nowhere near as popular a social media network as Facebook, but it's essentially being forced upon millions of YouTube users who don't want to lose their ability to comment on videos" and "Discussion forums across the Internet are already bursting with outcry against the new comment system". In the same article Melvin goes on to say:"  Answer:

Problem: Question: "Who remained the foremost head of state according to the 1912 compromise in China"  Context: "In 1912, the Republic of China was established and Sun Yat-sen was inaugurated in Nanjing as the first Provisional President. But power in Beijing already had passed to Yuan Shikai, who had effective control of the Beiyang Army, the most powerful military force in China at the time. To prevent civil war and possible foreign intervention from undermining the infant republic, leaders agreed to Army's demand that China be united under a Beijing government. On March 10, in Beijing, Shikai was sworn in as the second Provisional President of the Republic of China."  Answer:

A: Sun Yat-sen

Problem: Given the question: Question: "What can be measured to have a value of zero?"  Context: "QED vacuum has interesting and complex properties. In QED vacuum, the electric and magnetic fields have zero average values, but their variances are not zero. As a result, QED vacuum contains vacuum fluctuations (virtual particles that hop into and out of existence), and a finite energy called vacuum energy. Vacuum fluctuations are an essential and ubiquitous part of quantum field theory. Some experimentally verified effects of vacuum fluctuations include spontaneous emission and the Lamb shift. Coulomb's law and the electric potential in vacuum near an electric charge are modified."  Answer:

The answer is:
fields

input question: Question: "What was significant for the future of the country?"  Context: "Towards the end of the Republic, religious and political offices became more closely intertwined; the office of pontifex maximus became a de facto consular prerogative. Augustus was personally vested with an extraordinary breadth of political, military and priestly powers; at first temporarily, then for his lifetime. He acquired or was granted an unprecedented number of Rome's major priesthoods, including that of pontifex maximus; as he invented none, he could claim them as traditional honours. His reforms were represented as adaptive, restorative and regulatory, rather than innovative; most notably his elevation (and membership) of the ancient Arvales, his timely promotion of the plebeian Compitalia shortly before his election and his patronage of the Vestals as a visible restoration of Roman morality. Augustus obtained the pax deorum, maintained it for the rest of his reign and adopted a successor to ensure its continuation. This remained a primary religious and social duty of emperors."  Answer:???
output answer: Augustus obtained the pax deorum, maintained it for the rest of his reign and adopted a successor to ensure its continuation

Question: "What about Gaddafi was kept a secret?"  Context: "On the afternoon of Gaddafi's death, NTC Prime Minister Mahmoud Jibril publicly revealed the news. Gaddafi's corpse was placed in the freezer of a local market alongside the corpses of Yunis Jabr and Mutassim; the bodies were publicly displayed for four days, with Libyans from all over the country coming to view them. In response to international calls, on 24 October Jibril announced that a commission would investigate Gaddafi's death. On 25 October, the NTC announced that Gaddafi had been buried at an unidentified location in the desert; Al Aan TV showed amateur video footage of the funeral. Seeking vengeance for the killing, Gaddafist sympathisers fatally wounded one of those who had captured Gaddafi, Omran Shaaban, near Bani Walid in September 2012."  Answer:
----
Answer: buried at an unidentified location in the desert

Q: Question: "Which of the following is a flight muscle: the pectoralis, the skeleton, or the forelimb?"  Context: "Most birds can fly, which distinguishes them from almost all other vertebrate classes. Flight is the primary means of locomotion for most bird species and is used for breeding, feeding, and predator avoidance and escape. Birds have various adaptations for flight, including a lightweight skeleton, two large flight muscles, the pectoralis (which accounts for 15% of the total mass of the bird) and the supracoracoideus, as well as a modified forelimb (wing) that serves as an aerofoil. Wing shape and size generally determine a bird species' type of flight; many birds combine powered, flapping flight with less energy-intensive soaring flight. About 60 extant bird species are flightless, as were many extinct birds. Flightlessness often arises in birds on isolated islands, probably due to limited resources and the absence of land predators. Though flightless, penguins use similar musculature and movements to "fly" through the water, as do auks, shearwaters and dippers."  Answer:
A:
pectoralis
