I'm taking a test and have to guess the right answer to the question after the article. Article: 3D printers are certainly the superstar today---they are being put to all kinds of uses, including creating model cars for movies. However, none of these ideas are as crazy as the one suggested by Anjan Contractor, who believes that they will be the key to ending world hunger . If you think that sounds a little crazy, you are not the only one, but after hearing scientists, the idea seems to become true. According to scientists, food will become _ expensive and possibly, even out of reach, for billions of people in the future. It means billions of people won't have enough food. This is where 3D printers may save the day. Anjan, an engineer says that the only way to support the large population will be to provide every kitchen with a 3D printer and print out meals. More importantly, it would be to make the basic food from things that we now do not think can be eaten. Anjan thinks that we could easily get the meat protein from insects . Similarly, the vegetable nutrition could be made from greens like grass. Would you want to try 3D printed food? Question: From the passage we know that _ .

I'm taking a test and have to guess the right answer to the question after the article. Article: It is easier to go down a hill than to climb up a hill, so it is to fall into bad habit than into good ones. Bad habits do not come suddenly. They come little by little while people do not notice their danger. Some schoolboys first pick up bad habits in school and on the streets. When they cannot finish their lessons, they copy from their classmates. If they see bigger boys smoking, they also want to learn to smoke. When they are older, the habits become so strong that they can never get rid of them. From copying, they fall behind, then learn to steal, and smoking is bad for their health. At last they become worse and worse. How necessary it is that we get rid of the bad habits at the very beginning. Question: " get rid of " here means _ .
