Jack had gone to the university to study history, but he kept playing all the time and at the end of his first year, his history professor failed him in his exams. He was so poor at his subject that he would have to leave the university. However, his father made up his mind that he would go to see the professor to ask him to let Jack go on his studies the next year. "He's a good boy," said the father, "and if you let him pass this time, I'm sure he'll improve a lot next year and pass the exam at the end of it really well." "No, no, that's quite impossible." said the professor at once, "Do you know, last month I asked him when Napoleon had died, and he didn't know!" "Please, sir, give him another chance." said Jack's father. "You see, I'm afraid we don't take any newspapers in our house, so none of us even know that Napoleon was ill." 1. What was Jack studying?

input: Make use of the article to answer the questions. So, there was this kid named Jack that came up to my beanstalk one day. I couldn't believe my eyes, so I put down my ham sandwich I was eating and looked at him. I'm not sure what he thought he was doing there, but he sure did talk a lot. He kept asking me questions about this and then he asked me some questions about that and I was getting a little bit tired of all of the questions.

When I thought I wouldn't hear the end of everything, this Jack kid asked me about the one and only secret that I've always kept to myself. That no one even knew about! No, it wasn't about my golden guitar or even my goose that laid eggs filled with coins. No, he was asking me about my beans and their roots.

You see, I'm a giant and my job is to make sure the bean roots that we use to get down to earth are well protected and guarded. They're what helps us get down to the little person world when we need to. I became a little bit worried as the little kid asked more and more questions about my roots. I didn't want to tell him that my roots were hidden in the library!

I walked over to him to pick this little kid up to get him to quiet down about the bean roots, well, he got me with his little knife and I dropped him! Thankfully, he didn't get hurt or I would've been so sad!

He ran down the beanstalk when I chased after him. I guess he wanted to get back to his little people. I didn't follow him, but I sure hope he doesn't come back for my stuff. 1. Who looks after the bean roots?

It's one of the most controversial practices in agriculture: feeding small amounts of antibiotics to animals in order to make them grow faster. But what if the drugs don't even work very well? There's some good evidence that they don't, at least in pigs. They used to deliver a boost in growth, but that effect has disappeared in recent years or declined greatly. The reason for this is interesting and even paradoxical. Researchers think the antibiotics used to work by suppressing low-grade infections. In recent years, however, pork producers found other ways to accomplish the same thing through improved hygiene . As a result, the drugs have become largely superfluous -- yet many farmers still use them.

To understand how this happened, you have to step back in time, says Steve Dritz, a specialist in pig nutrition at Kansas State University. Sixty years ago, when antibiotics were new, "people started treating animals, and feeding [the antibiotics], and finding that they had increased growth rates and feed efficiencies," he says. Nursery-age pigs, for instance, grew 12 to 15 percent faster with antibiotics. The animals also needed less feed to reach full weight. Other studies showed similar results in chickens and cattle. In the 1980s, a new set of studies found similar effects. So the growth-promoting effects of antibiotics became standard practice among meat producers.

Fast forward to the 1990s. Dritz was starting his career as a scientist at Kansas State University, and pork production was changing dramatically.

Previously, pigs were born and raised in one barn or in several barns close together. This meant infections could easily pass from one generation to the next, the way that kids share germs between their friends on the playground and their parents at home. Under the new system, when piglets are weaned, they move to a whole different place. That new site is carefully scrubbed and free of disease.

Craig Rowles, who runs a large swine operation in Carroll, Iowa, shows me one such room. There's not a piglet in sight. "This room just got completely washed and disinfected, and now it's going to sit here and dry for a while," he says.

A whole group of pigs will come in here together, and later they will move out together to yet another site. "That group of pigs will stay together until they go to market," Rowles says.

The groups are kept strictly separated from each other. If workers move between the groups, they first have to change their boots.

When farmers adopted multisite production, it cut down on disease -- and pigs actually grew faster. 1. Are pig farmers still using drugs?
