Context: The direct thrombin inhibitor dabigatran and the anti-Xa agents rivaroxaban, edoxaban, and apixaban are a new generation of oral anticoagulants. Their advantage over the vitamin K antagonists is the lack of the need for monitoring and dose adjustment. Their main disadvantage is currently the absence of a specific reversal agent. Dabigatran's, unlike the anti-Xa agents, absorption can be reduced by activated charcoal if administered shortly after ingestion and it can be removed from the blood with hemodialysis. Prothrombin complex concentrate, activated prothrombin complex concentrate, and recombinant factor VIIa all show some activity in reversing the anticoagulant effect of these drugs but this is based on ex vivo, animal, and volunteer studies. It is unclear, which, if any, of these drugs is the most suitable for emergency reversal. Three novel molecules (idarucizumab, andexanet, and PER977) may provide the most effective and safest way of reversal. These agents are currently in premarketing studies. 
 Question: Idarucizumab is an antidote of which drug?

Ex Output:
dabigatran

Context: What did the arrival of the Internet and 24 hours news mean for British newspapers? At first, this looked like the end of printed newspapers. The national newspapers were worried that they would lose all the readers, so most of them decided to create an online version . But they still had a problem. How to make money? There was simply too much news and too much information freely available "out there". But was it accurate ( )? Whose opinions should we trust? A survey for a "good newspaper", and most of those said.they believe more of what they read in paid-for newspapers. Here was something newspapers understood--here was what they could offer: news plus comment and opinion. And the Internet now offered new opportunities. A newspaper was just that: news printed on paper. But the Internet now offered newspapers different places to print, and in different media. Many newspapers now have podcasts and video too. This may explain why the readership of newspaper online in the UK is very different from people who read printed newspapers. The most popular newspaper in the UK is The Sun, The "mid-market" audience mainly reads The Daily Mail. Online, it's a different story. The most popular is The Mail. And the next popular site is TheGuardian. In fact many of these browsers are not from the UK. The Mail and Guardian are among the most read newspapers in the USA. The Guardian, may become the largest English language paper on the web; a website with a newspaper attached! 
 Question: The largest English language paper on the Internet may be .

the guardian

Context: Matt and his wife lived in the country. Matt was very mean and hated spending money. One day a fair came to the nearby town. They went to the fair and looked at all the things to buy. Matt's wife wanted to buy a hat only costing $28, but was refused. Later on, a comb of $5 attracted her attention, but he would not let her spend any money. Then, in a nearby field, they saw a small airplane. "Fun flight!" the notice said, "$10 for 10 minutes." Matt had never been in an airplane and he wanted to go on a fun flight. However, he didn't want to pay for his wife either. "I've only got $10," he told the pilot. "Can my wife come with me for free?" The pilot wasn't selling many tickets, so he said, "I'll make a bargain with you. If your wife doesn't scream, she can have a free flight." Matt agreed, and got into the small airplane with his wife. The pilot took off and made his airplane do all kinds of things. At one moment it was flying upside down. When the plane landed, the pilot said, "OK, your wife didn't make a sound. She can have her ride free." "Thank you," Matt said, "it wasn't easy for her, you know, especially when she fell out." 
 Question: How much did the couple spend at the fair?

$10.
