In this task, you're given an article and an answer. Your task is to generate the fill-in-the-blank question for this answer based on the given article. The blanks are always at the end of the question, and can be filled with more than one word or phrase.

Input: Consider Input: Article: If you look at the night sky, you'll often see stars moving very quickly. In fact, they move much more quickly than they should according to their size and the laws of physics. Scientists do not completely understand why the speed of these stars is so high. But many believe the reason is that much of the universe is made of something called "dark matter". Groups of stars called galaxies, such as the Milky Way, might even be made up of 90 percent dark matter. How much something weighs depends on where it is. The same object weighs only half as much on Mars as it does on Earth and almost three times as much on Jupiter. So scientists prefer to talk about the mass of something rather than how much it weighs, because mass does not change. They can work out the mass of galaxies by measuring the distance between them and the speed they move at. Recently, Jorge Penarrubia, a senior academic at Edinburgh University, UK, and his team discovered something interesting: The mass of the Milky Way is only half as much as the mass of another nearby galaxy, Andromeda. This seems strange, and dark matter may explain why. Finding out more about dark matter could help us understand how the universe began, but this is not easy. Lots of scientists with different types of expert knowledge are working on the problem. We can't see dark matter, it's very difficult to measure and we can't find out its mass. Unlike stars, dark matter doesn't produce or reflect light. But we can make a good guess that it is there because of the way things move and the way light bends. Experts now think dark matter may be very different from the matter that we find on Earth. There may also be five times as much dark matter in the universe as ordinary matter.
Answer: 7.5 kg; 45 kg

Output: Something that weighs 15kg on Earth weighs about _ on Mars and _ on Jupiter.

Input: Consider Input: Article: The Massachusetts Institute of Technology (MIT) is a private research university in Cambridge, Massachusetts, founded in 1861 in response to the increasing industrialization of the United States. The institute stressed laboratory instruction in applied science and engineering. MIT's early emphasis on applied technology at the undergraduate and graduate levels led to close cooperation with industry. Curricular reforms under Karl Compton and Vannevar Bush in the 1930s emphasized basic science. MIT was elected to the Association of American Universities in 1934. Today, the institute comprises various academic departments with a strong emphasis on scientific, engineering, and technological education and research. MIT is one of the most selective higher learning institutions, and received 18,357 undergraduate applicants for the class of 2018 -- only admitting 1,419, an acceptance rate of 7.73%. MIT's 168-acre campus spans approximately a mile of the north side of the Charles River basin in the city of Cambridge. The campus is divided roughly in half by Massachusetts Avenue, with most dormitories and student life facilities to the west and most academic buildings to the east. MIT's on-campus nuclear reactor is one of the most powerful university-based nuclear reactors in the United States. In 1999 Bill Gates donated $20 million to MIT for the construction of computer laboratory named the "William H. Gates Building". While Microsoft had previously given financial support to the institution, this was the first personal donation received from Gates. Other notable campus facilities include a pressurized wind tunnel and a towing tank for testing ship and ocean structure designs.
Answer: became a member of the Association of American Universities in 1934

Output: From the passage, we know MIT _ .

Input: Consider Input: Article: If you see a group of kids hitting and abusing an animal, would you stop them? Would you at least call the police? Again people would walk away. Some people do not believe that animal abuse is a big issue. Every day animals are abused in their homes or on the streets. It seems as if politicians do nothing to stop this issue. Everyone is worried about education and global warming. What about animals? We should not ignore them just because they cannot talk to us. Animals, like us humans, have rights. Every living being has the right to warm shelter and good food, but most importantly, they have the right to be wanted and loved. They have the right to be a special, much loved member of their own family. There are many organizations that deal with abused animals or animals that have no home like ASPCA, PETA, the Humane Society and many more. There are organizations that deal with this issue, but that does not mean that we still shouldn't help. The biggest saying that bothers me is, "I am only one person. I can't make a difference." If everyone thought like that, we wouldn't have the organizations and loving people who help the world every day. By helping one animal, you are making a difference. There are many things you can do right now to help animals around your neighborhood. You can volunteer at your local animal shelter, raise money for animal shelters, inform your community about animal abuse or you can write to your representatives and tell them that animal abuse needs to be taken seriously. As you walk down the street, try to help any animals you see walking around. You can easily buy a cheap box of dry cat or dog food to feed the animals. If we do not help our animals now, we may never have animals again. Always remember that with every step you take, you help save an animal's life and isn't that worth fighting for?
Answer: they don't take animal abuse seriously
Output: Some people won't stop kids from abusing animals because _ .
