Input: 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.
"Did Landau use dynamical spacetime in his theory, if not, what?" is "No, it uses translation invariance"?

Input: An archaeological party explore some caverns underground . Dr. Campbell and Dr. Hughes are the two leaders of the archaeological expedition , and get separated . While Dr. Hughes finds an alien corpse with a fossilized diamond , Dr. Campbell finds hieroglyphics at the cost of the party except for Hughes and himself . Two years later , Campbell and his assistant Holly are digging up the bones of Yonggary , a gargantuan dinosaur 50 times the size of a tyrannosaurus rex . Out of nowhere , people slowly are being killed around the site . While Holly is working Dr. Hughes , who has been legally dead for 2 years , goes to Holly and tells her to stop the dig . Dr. Campbell comes into the tent and sends Dr. Hughes off . Holly quits the expedition when another '' Accident '' occurs . In the town bar , Dr. Hughes finds Holly and takes her back to her Hotel room to tell her why he thinks the bones of the Dinosaur , Which he calls Yonggary , are going to bring the end of the world . After explaining , Holly and Hughes go to the site to stop Campbell but it is too late and Aliens resurrect Yonggary . After Yonggary's first appearance , the Army comes in and takes Holly and Campbell to an army base when Yonggary is dispatched by the aliens again . The army sends choppers after Yonggary , but he destroys them . Yonggary is then sent to the city and does some damage , where some jets attack him . Then Yonggary is transported to a power plant where he is attacked by rocket pack soldiers . During the fight , Hughes and Holly find out that the diamond on Yonggary's forehead is the device giving the aliens control of Yonggary .
"What are the three things that attack Yonggary?" is "Aliens"?
Output: no
Input: In India to purchase some horses , British aristocrat , Lord Esketh and his wife , Edwina , come to the town of Ranchipur at the invitation of the elderly Maharani . Their marriage is an unhappy one and Lord Esketh announces his intention to return to England and begin divorce proceedings . The spoiled , insensitive Edwina scoffs at this . She renews in Ranchipur an acquaintance with a former lover , Tom Ransome , now a dissolute alcoholic . She also meets and attempts to seduce a distinguished Hindu physician , Dr. Rama Safti , a decent man who is the elderly Maharani's personal choice to succeed her someday . Safti at first resists , but ultimately succumbs to Edwina's charms and falls hopelessly in love with her . Lord Esketh becomes aware of this , but Safti saves him from a man-eating tiger during a safari . Safti admits his love for Edwina to Lord Esketh , who is now sympathetic toward this good man's plight . Ransome feels the same way , warning Edwina to stay away from Safti , a friend he admires . Edwina similarly falls into disfavor with the Maharani , who explains that Safti has been raised to lead a pure life and that Edwina is unworthy of him . Ranchipur suddenly is ravaged by a natural disaster , an earthquake and flood . Dr. Safti is so busy saving lives that he can not personally care for Edwina , who has fallen ill . Ransome looks after her as well as for young Fern Simon , who has declared her love for him . When a dam is exploded by dynamite and as a result the flood waters recede , it is Dr. Safti who reveals that Ransome is the one who risked his personal safety to save the people of Ranchipur .
"Where did Edwina meet Dr. Rama Safti?" is "Ranchipur, India"?
