The center of an atom is held together by powerful forces. This gives them a huge amount of stored energy. This type of energy is called nuclear energy. This energy can be released and used to do work. This happens in nuclear power plants where they split apart the nucleus of an atom. This splitting apart is called nuclear fission. Another type of nuclear energy happens in the Sun. Here the atoms nuclei are not split apart. Instead, the nuclei of the atoms are fused, or joined together. This process is called nuclear fusion. Some of the suns energy travels to Earth. This energy from nuclear fusion warms the planet and provides the energy for photosynthesis.

Question: "Do the atoms nuclei in the Sun split apart?"

OPTIONS:
- no
- yes

Answer: "Once in a while"

Response: no

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.

Question: "Did Landau use dynamical spacetime in his theory, if not, what?"

Response: "Non-covariant"

Problem: (CNN) -- We'll let you finish, but The Muppets have the best Instagram account of all time. The feed was launched just over a month ago as part of a promotional push for their upcoming movie, "Muppets Most Wanted." But in between quippy posters and ads for the film, which is a sequel to 2011's blockbuster "The Muppets" with Jason Segel, there are ingenious "selfies" from the Muppets crew. In fact, the first post was a coy snapshot from Kermit, Miss Piggy and Gonzo, with a filter in full effect: And the selfies grew more adorable -- and more hilarious -- from there: We now have evidence of the time Animal burst in on Beaker in the bathroom. And we know what Gonzo does after a hard day of stunts. "Gonzo treated himself to a massage today to try to work out all of his stuntman kinks. Even weirdos need pampering. #bougielife #yolo," reads the caption to this pic: The Muppets' curmudgeonly yet lovable critics, Statler and Waldorf, are still trying to get the hang of taking the perfect selfie -- "This is the fanciest calculator we've ever seen!" they were heard saying when the photo was taken -- while Rowlf is clearly a selfie king. From the Swedish Chef to Miss Piggy's evil alter ego, everyone has gotten in on the first-person photo sessions. The only people noticeably missing from the account are the Muppets' human co-stars in "Muppets Most Wanted," like Tina Fey, Ty Burrell and Ricky Gervais. As with the first "Muppets" film, which also starred Amy Adams, Chris Cooper and Rashida Jones, the "Muppets" sequel has plenty of human star power. In addition to Fey and Gervais, "Muppets Most Wanted" also has appearances from Tom Hiddleston, Salma Hayek, Stanley Tucci and Lady Gaga.

Question: "What movie are the selfies of Kermit, Miss Piggy and Gonzo from?"

Answer: "Muppet Treasure Island"

OPTIONS:
- no
- yes

Question:
Joe's parents are farmers and they have a huge farm with cows, chickens, and ducks. Joe loves the farm and all the things he gets to play around and play on. One day, Joe's father told him not to get near a tractor that was sitting in the field. His father was worried that Joe would climb on it and hurt himself. Joe went out to the field and was feeding the horses and cows. When he was done, he saw the tractor his father told him not to get near. He knew that climbing on the tractor wouldn't hurt anything, so he did. He climbed on to the seat and sat there. Then, he pretended he was his father and pretended that he was driving the tractor. Joe's father saw him playing on the tractor and called for him. Joe heard his father calling for him and got off the tractor really fast. When he did that, he fell off and hurt his arm. Joe was in pain and his father came running to check on him and picked him up and sat him on a bench and asked him why he did that. Joe looked at his father and said, "I wanted to be like you." Joe's father gave him a hug and asked him if he wanted to ride with him on the tractor. Joe did and after he got a bandage on his arm, he and his father rode in the field on the tractor. After reading the above, is "Chickens" the correct answer to the question "Which animals were present on the farm?"? OPTIONS:
- no
- yes

Answer:
yes

In 1878, Martinez Campos was Governor-General of Cuba, and Maximo Gomez was Commander-in-Chief of the Cuban forces. Both parties were weary of the prolonged hostilities, and neither was able to compel the other to surrender. Spain, however, professed a willingness to yield an important part of the demands of her rebellious subjects. Martinez Campos and Gomez met at Zanjon and, on February 10, 1878, mutually agreed to what has been variously called a peace pact, a treaty, and a capitulation. The agreement was based on provisions for a redress of Cuban grievances through greater civil, political, and administrative privileges for the Cubans, with forgetfulness of the past and amnesty for all then under sentence for political offences. Delay in carrying these provisions into effect gave rise to an attempt to renew the struggle two years later, but the effort was a failure. Matters then quieted down for a number of years. The Cubans waited to see what would be done. The Spanish Governor-General still remained the supreme power and, aside from the abolition of slavery, the application of the Spanish Constitution and Spanish laws to Cuba, and Cuban representation in the Cortes, much of which was rather form than fact, the island gained little by the new conditions. Discontent and protest continued and, at last, broke again into open rebellion in 1895.

Question: "Where Governor-General of Cuba and Commander-in-Chief of Cuban forces met to make a peace pact?"

OPTIONS:
- no
- yes

Answer: "In Zanjon"

Response:
yes
