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.

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

Example Input: Article: Shirley Chisholm was best known as the first black woman elected to the United States Congress and the first black woman to run for president of the United States.

Answer: the UK had a better education system than the USA

Example Input: Article: Jack was born without eyes. He's very lucky with his timing. He grew up having other kittens to play and socialize with, and was used to people from the moment he was born since there are always kids hanging around the barn. He was a favorite amongst the students at the barn. However, when it came time to find the kittens homes, no one knew where Jack would end up. That's when I got an e-mail from my friend. All she asked was "Do you still want one of the kittens? There's one here with no eyes and no one can take him." Without thinking I told her that I did want the kitten. When we first brought him home Jack walked cautiously around, sniffing everything. He went through a time when he could climb the stairs, but couldn't get down. He would sit at the top and cry until someone came and got him. Every now and then when he gets disoriented he'll stop and cry. But we just call his name and talk to him and it isn't long before he finds his way back to us. Also, a few weeks after getting Jack, we got a new barn cat named Bear. I always take Jack outside at that time for some fresh air and exercise. He loves to run (at top speed!) around the backyard and gardens. Bear and Jack have become best friends. Jack always knows when Bear is around. He'll run across the yard straight to Bear and wrap his front legs around his neck in a big hug. When they're tired they'll lie down in the grass together. Jack is truly an inspiration. I've owned a lot of kittens in my life, but Jack is the happiest, most playful of them all. People who know Jack don't feel sorry for him. They cherish him for the treasure that he is. I have talked to a few people who haven't met him personally and tend to pity him, but they just don't understand. Jack doesn't need pity. I think that cats like him don't have disabilities; they have adaptabilities.
Answer: always needed someone to guide him
Example Output:
When Jack first came to the author's house, he _ .
