In this task, you will be presented with a context passage, a question about that paragraph, and a possible answer to that question. The task is to check the validity of the answer. Answer with "Yes" or "No".

Q: General relativity includes a dynamical spacetime, so it is difficult to see how to identify the conserved energy and momentum. Noether's theorem allows these quantities to be determined from a Lagrangian with translation invariance, but general covariance makes translation invariance into something of a gauge symmetry. The energy and momentum derived within general relativity by Noether's presecriptions do not make a real tensor for this reason. Einstein argued that this is true for fundamental reasons, because the gravitational field could be made to vanish by a choice of coordinates. He maintained that the non-covariant energy momentum pseudotensor was in fact the best description of the energy momentum distribution in a gravitational field. This approach has been echoed by Lev Landau and Evgeny Lifshitz, and others, and has become standard. The use of non-covariant objects like pseudotensors was heavily criticized in 1917 by Erwin Schrodinger and others. <sep>When did the standard approach to energy momentum become criticized?<sep>1911

Q: (CNN) -- Gabriel Garcia Marquez, widely regarded as one of the most important contemporary Latin American authors, was admitted to a hospital in Mexico earlier this week, according to the Ministry of Health. The Nobel Prize recipient, known as "Gabo," had infections in his lungs and his urinary tract. He was suffering from dehydration, the ministry said. Garcia Marquez, 87, is responding well to antibiotics, but his release date is still to be determined. "I wish him a speedy recovery." Mexican President Enrique Pena wrote on Twitter. Garcia Marquez was born in the northern Colombian town of Aracataca, the inspiration for the fictional town of Macondo, the setting of the 1967 novel "One Hundred Years of Solitude." He won the Nobel Prize for literature in 1982 "for his novels and short stories, in which the fantastic and the realistic are combined in a richly composed world of imagination, reflecting a continent's life and conflicts," according to the Nobel Prize website. Garcia Marquez has spent many years in Mexico and has a huge following there. Colombian President Juan Manuel Santos said his country is thinking of the author. "All of Colombia wishes a speedy recovery to the greatest of all time: Gabriel Garcia Marquez," he tweeted. CNN en Espanol's Fidel Gutierrez contributed to this story. <sep>Whose speedy recover did Mexican President Enrique Pena wish on Twitter?<sep>Gabriel Garcia Marquez

Q: This week, we've been treated to the increasingly familiar sight of former NBA star and provocateur Dennis Rodman attending events in Pyongyang, North Korea. It's his fourth trip in less than 12 months. On Tuesday, an angry Rodman defended his visit in a CNN interview straight from Pyongyang, at one point saying to "New Day" anchor Chris Cuomo, "I don't give a rat's ass what the hell you think ..." in response to question about Kenneth Bae, an American detained in North Korea. When will we tire of this circus? In case you don't watch cable news, you might miss that the media really loves this kind of thing. No story about North Korea is too weird to go unreported, even if there is no real information to disseminate. Recall the recent rumor that Kim Jong Un's uncle was executed by being fed to hungry dogs, which most likely was started as satire on Chinese social media but was at first reported widely in the media (CNN was unable to confirm and did not report the story). In media discourse, North Korea is the classic enemy. The regime's injustices, quirks and dysfunctions are reassuring to Americans that their own country is just the opposite: Normal, well-functioning, a land of peace and liberty. But add in Rodman to the North Korea story, and it's bound to produce eye-popping headlines: The Weird American Athlete Goes to Weird Country story is just too easy not to cover. Rodman himself seems to be thriving on finding a strange smidgen of relevance through his visits to North Korea (and perhaps a Paddy Power paycheck). Though often described as quite shy, he has always enjoyed challenging the values of Middle America. North Korea is providing him a new avenue to be in the spotlight. The most passive player in this tragicomedy is Rodman's home country, the United States. The U.S. State Department has deployed the rhetorical equivalent of an embarrassed teenager whose dad has shown up to dance at his prom. Something along the lines of "this has nothing to do with us" is what the State Department has said with every one of Rodman's trip. Last winter,the State Department criticized Rodman's timing as it followed a nuclear test and rocket launch. <sep>Dennis Roman, whom has made four trips in the last 12 months, has recently attended events in which city in North Korea?<sep>Soule, Pyungala, Siagon
