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: You might want to know how cold it is. You may need to know how fast the wind is blowing. Maybe it rained last night? Do you know how much? Does it feel humid to you? You have heard all these questions before. To answer these questions, we need data. That data comes from special tools. These tools collect data about the weather. You can see some of the common tools listed below: A thermometer measures temperature. An anemometer measures wind speed. A rain gauge measures the amount of rain. A hygrometer measures humidity. A wind vane shows wind direction. A snow gauge measures the amount of snow. <sep>What question does a rain gauge answer?<sep>Measures the amount of rain

A: Yes

Q: Surviving being shot and stabbed at the end of the previous film , the stepfather has been institutionalized in Puget Sound , Washington since , spending his time building model houses in the workshop . Assigned a new doctor named Joseph Danvers the stepfather begins confiding in him to gain his trust , ultimately murdering the doctor during a session by stabbing him in the neck with a blade smuggled out of the workshop . After killing Danvers the stepfather beats a suspicious guard named Ralph Smith to death with his own nightstick with only two strikes and takes his uniform , successfully sneaking out of the sanitarium . Checking into a hotel after robbing and murdering a traveling salesman the stepfather alters his appearance , takes the name Doctor Gene F. Clifford from the newspaper obituaries and travels to Palm Meadows , Los Angeles after seeing an ad for it on an episode of Dream House . Gene arrives in Palm Meadows and meets real estate agent Carol Grayland and leases a house just across the street from her and her son Todd . During a session with the wives of the neighborhood , Gene learns Carol 's dentist husband , Philip had absconded with his mistress the previous year . Gene begins courting Carol , eventually winning over her and Todd . Gene 's plan to marry Carol is soon complicated when Phil returns , wanting to reconcile with his wife . Needing Phil out of the way , Gene persuades Carol to send Phil over for a meeting , during which Gene kills him with a broken bottle , covering up Phil 's disappearance afterward by arranging it so that it looks as though he simply ran off again . <sep>Which three items does the stepfather use to kill Joseph, Ralph and Phil?<sep>A blade, a nightstick, a broken bottle
