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.

Does the response "Non-covariant" correctly answer the question "Did Landau use dynamical spacetime in his theory, if not, what?"?

The Mummy 's Shroud is set in 1920 and tells the story of a team of archaeologists who come across the lost tomb of the boy Pharaoh Kah-To-Bey . The story begins with a flash back sequence to Ancient Egypt and we see the story of how Prem , a manservant of Kah-To-Bey , spirited away the boy when his father was killed in a palace coup and took him into the desert for protection . Unfortunately , the boy dies and is buried . The story then moves forward to 1920 and shows the expedition led by scientist Sir Basil Walden and business man Stanley Preston finding the tomb . They ignore the dire warning issued to them by Hasmid , a local Bedouin about the consequences for those that violate the tombs of Ancient Egypt and remove the bodies and the sacred shroud . Sir Basil is bitten by a snake just after finding the tomb . He recovers , but has a relapse after arriving back in Cairo . Preston takes advantage of this and commits him to an insane asylum , to take credit for finding the tomb and Prince 's mummy himself . Meanwhile , after being placed in the Cairo Museum , the mummy of Prem is revived when Hasmid chants the sacred oath on the shroud . The mummy then proceeds to go on a murderous rampage to kill off the members of the expedition , beginning with Sir Basil after he escapes from the asylum . One by one , those who assisted in removing the contents of the tomb to Cairo are eliminated by such grisly means as strangulation , being thrown out of windows , and having photographic acid thrown in their face .

Question: "When was Sir Basil bitten, and does he recover?"

OPTIONS:
- no
- yes

Answer: "When he arrived in Cairo, and he didn't survive"

Response: no

The Golden Heian Era: The geomancers in 794 decided that Heian-kyo (modern Kyoto) would be an auspicious site for the imperial family. It was indeeduntil 1869. Grants of tax-free land over the years had been made to Buddhist temples and members of the court aristocracy. The most powerful families thus carved out for themselves whole regions that were to become the fiefdoms of Japanese feudalism. By the end of the eighth century the clans had created a hierarchy of shiki, or rights, from the highest to the lowest ranks of society. The aristocrat or court patron lent his prestige to a powerful provincial proprietor, who employed a competent estate-manager to oversee smallholders, who in turn worked their farms with dependent laborers. This elaborate structure of interdependent rights and obligations was to serve Japanese society right into the 20th century. Meanwhile, Heian court life blossomed in an effusion of aesthetic expression. Princes and princesses judged the merits of birds, insects, flowers, roots, or seashells. Literary party games held in ornate palace gardens required each guest to compose a small poem as his wine cup floated toward him along a miniature winding channel of water. Expeditions were organized to the best viewing points for the first spring cherry blossoms, and special pavilions were built to watch the rising of the full moon. Every gesture, from the most banal opening of an umbrella to the sublimest act of lovemaking, had its appropriate ceremonial. Conversation often took the form of elegant exchanges of improvised verse. The changing role of Chinese culture in Japanese life was epitomized in the language itself. In the absence of an indigenous alphabet, Japanese scholars had with the greatest difficulty tried to adapt the complex ideograms of monosyllabic Chinese to the essentially polysyllabic Japanese. Thus developed the katakana system used as a vehicle for writing Buddhist names and concepts. After rival Fujiwara factions had been struggling for years to gain control of the imperial throne, they turned to the Taira and Minamoto armies in 1156 to wage the four-year war that heralded the end of the golden age of the Heian court. The Taira, controlling the region along the Inland Sea, defeated the Minamoto armies based in the Kanto province east of the capital.

Question: "The changing in Chinese culture in Japanese life eventually had what written language develop?"

Response: "Indigenous alphabet"

863. INGREDIENTS.--The remains of a boiled calf's head, 1-1/2 pint of the liquor in which the head was boiled, 1 blade of pounded mace, 1 onion minced, a bunch of savoury herbs, salt and white pepper to taste, thickening of butter and flour, the yolks of 2 eggs, 1 tablespoonful of lemon-juice, forcemeat balls. _Mode_.--Remove all the bones from the head, and cut the meat into nice square pieces. Put 1-1/2 pint of the liquor it was boiled in into a saucepan, with mace, onion, herbs, and seasoning in the above proportion; let this simmer gently for 3/4 hour, then strain it and put in the meat. When quite hot through, thicken the gravy with a little butter rolled in flour, and, just before dishing the fricassee, put in the beaten yolks of eggs and lemon-juice; but be particular, after these two latter ingredients are added, that the sauce does not boil, or it will curdle. Garnish with forcemeat balls and curled slices of broiled bacon. To insure the sauce being smooth, it is a good plan to dish the meat first, and then to add the eggs to the gravy: when these are set, the sauce may be poured over the meat.

Question: "Is the simmering in Sentence 4 done before or after the calf's head is boiled?"

Response: "During the boiling"
OPTIONS:
- no
- yes

A:
no
