Write a question from the passage such that it identifies a character (a person or a thing) in the passage.

[Q]: His eyes were open and his head bobbed around at an impossible angle. He was sitting in about forty feet of water, stone dead, one arm pinned between the rocks. As best I could tell, he had been dead when he landed there. The mud and ooze around him were as serene and smooth as he was. The cop who was assisting me swam over and made a palms up gesture. I shrugged back at him and began to work the body loose. The corpse had only one leg, and as I worked I wondered what he had been doing in the lake. I got the arm free and kicked toward the quicksilver surface above me. The body turned bloated and heavy when I broke water with it, and it took three of us to load it into the police launch. I dried off and got a coke out of the cooler. It was getting to be another Texas scorcher, and the sunlight bouncing off the surface of the lake felt like it had needles in it. My mouth was dry from breathing canned air and the carbonation burned like fire. Winslow, from the sheriff's office, sat down next to me. 'I appreciate this, Dan,' he said. 'No problem.' Sam Winslow and I had grown up together about twenty miles outside Austin in a little town called Coupland. We'd fought a lot as kids, and there were still plenty of differences in our politics and educations. But being on the police and fire rescue squad had brought me closer to him again, and I was glad of it. A private detective needs all the friends he can get. 'What do you make of it?' I asked him. 'Accidental drowning, looks like.' I raised an eyebrow but didn't say anything. 'He's got a bump on the head that could have come off a rock. We'll see what the coroner says.' 'Any idea who he is?' Winslow shook his head. He'd gained weight in his face recently and his jowls vibrated with the gesture.
[A]: Who got coke out of the cooler?

[Q]: It has become increasingly common for academics to use social media to communicate with wider audiences. Twitter, like many other social platforms, typically measures success in terms of numbers of followers, likes and retweets, but this only tells us something about the spreading of messages but not necessarily whether the content of the messages is understood or embraced. One way to ascertain this is through network and language analysis, which, used together, can tell us how effective the communication is.
Economists tweet less, mention fewer people and have fewer conversations with strangers than a comparable group of experts in the sciences, and use less accessible language with words that are more complex, with more abbreviations and with a more distant tone. Their tweets are less personal and less inclusive than those used by scientists.
This is what appeared in April 2017 when we gathered data on tens of thousands of tweets from the Twitter accounts of both the top 25 economists and 25 scientists as identified by IDEAS and Science, including the top three economists at the time, Paul Krugman, Joseph Stiglitz, and Erik Brynjolfsson and, on the other side, the top three scientists, Neil deGrasse Tyson, Brian Cox, and Richard Dawkins. At that time those accounts covered roughly two thirds of all the following.
The timing is significant because 2016 has been declared the year of post-truth politics, the year in which appeals to emotions (pathos) superseded the significance of factual evidence-based information (logos), affecting people's constructions and interpretations of events. This has been accompanied by the growing prominence of political "alt" movements (e.g. UKIP, the Alt-right) and their aggressive, provocative, and populist narratives, and "fake news" leading to political shock events such as Brexit and the Trump election.
The relatively low traction of economists in these public debates has been and continues to be an important issue. Does the public not trust economists? Don't they understand what economists do and how they work? Is their work misrepresented in the media? And how do economists themselves interact with public opinion?
[A]: Who's tweets' were analyzed?

[Q]: How long ago was it? It was a long time is all I know. For my birthday, my parents took me and my brother out of school on the day before my birthday and we took a train.
(Funny interjection, my mom was caught on the wrong side of the station so she ran across the rails and was pulled up by my dad a couple minutes before the train came.)
It was a night train, so we had our own room where my brother and I claimed the top as our territory.
(Look at my younger self's squinty eyes They are staring into your soul)
Anyways, it was morning by the time we arrived at where I would spend my birthday. Vienna, Austria.
I quickly got off the train in excitement taking in the view of the station like it was first time I had seen anything. We exited the station and took the trolley to get to our hotel. For breakfast, we had delicious, regional delicacies (among other things). They looked similar to crepes, but all I know is that it had a German name that I can't remember.
After we got situated in our hotel, we immediately headed off for the Mozart Plaza/Park.
My family and I also visited other monuments that day:
By the end of the day, our legs were worn out. We had rode so many trolleys and walked so much that I'm pretty sure that any longer and we would've collapsed on the spot. The bed never felt so good.
The following days we went to Austrian Castle, Ice Cave, and more buildings and such. The trip overall made this birthday the most memorable and the best thus far.
Bonus: We missed our night train back because of daylight saving hours. The trip back was definitely hectic, but adventurous.
