Q: “Hey, Natalie! Nice sweatshirt!” I was passing through the hallways of school last year, being messenger boy for the teachers, when this girl walked up to me. I had no clue who she was, but I thought she was a year younger than me. That’s why I thought it was weird that she said my name. But the “nice sweatshirt” bit was what really got me. I wasn’t even wearing my sweatshirt. So. There was a substitute teacher in my literacy class, so my class was split. half of us did actual work, and the other half watched a documentary. Ben, Evan, Isabelle and myself were put together in the class watching the super boring documentary. We got bored, so, when Ben left the classroom for a bit and left his jacket behind, I don’t remember why, but, I put on his sweatshirt and traded it for mine. This turned into everyone swapping sweatshirts for the next hour until school was out. At one point I was called to the office to deliver a message to a different classroom. I walked out of the office with the information, and turned around at the sound of my name. “Hey, Natalie! Nice sweatshirt!” I smiled and thanked her like the nice human being I want people to think I am. Once she started down the stairs I looked down at my sweatshirt. Black and orange? Nike? But my sweatshirt’s gray and purple! Then I remembered our little game of “try not to get caught swapping sweatshirts and giggling”. I wasn’t wearing my sweatshirt. Someone else had it. I was wearing Evan’s. It’s also kind of sad because that was one of the only compliments I’ve gotten from a stranger all year. Complimented on something that wasn’t even mine… Welcome to my life, everybody! According to the above context, answer the following question. How long have they been swapping sweathers?
Answer: They've been doing it all year

Q: WHITE HOUSE — President Donald Trump on Monday declared he has an "absolute right" to pardon himself and then also tweeted his assertion that the federal government investigation into ties between his 2016 election campaign and Russia is "totally unconstitutional." While Trump has frequently ignored established norms and challenged the understood limits of presidential powers, his latest comments are viewed by some legal scholars as unprecedented and testing constitutional boundaries. "I was shocked" by Trump’s tweets, said Susan Low Bloch, a law professor at Georgetown University. "No president has ever tried it," she told VOA News. "It’s unlikely the president can pardon himself. I think the court would say no" and if he did give himself a pardon, "most congresses would impeach him." Bloch also notes when most people accept a pardon "it’s an admission of guilt," thus it would be a bad idea for Trump to pursue such a course of action. The professor, who has testified before the Senate on whether a president can be indicted and tried while in office, says the special counsel is "absolutely constitutional." Another constitutional scholar, Keith Whittington at Princeton University, said, "I think it is important to note that the president’s comments reference serious arguments that are being debated by legal scholars, but these are difficult and unusual constitutional questions that would ultimately be answered in the courts." According to Northwestern University Law Professor Andrew Koppelman, "Trump's position on pardons is consistent with the Constitution's text, but inconsistent with the overall structure. It means that the President could commit capital treason, or any other federal crime, and then immediately pardon himself. "It means that he could commit murder in the White House," Koppelman said. "It makes no sense within the Constitution as a whole." Asked by reporters Monday about Trump’s comment on his ability to pardon himself, White House Press Secretary Sarah Sanders repeatedly replied: "The... According to the above context, answer the following question. Who does Whittington say will have to assess whether a self-pardon is legally valid or falls outside of the legal pardoning power?
Answer: The courts

Q: "They've got cameras everywhere, man. Not just in supermarkets and departments stores, they're also on your cell phones and your computers at home. And they never turn off. You think they do, but they don't. "They're always on, always watching you, sending them a continuous feed of your every move over satellite broadband connection. "They watch you fuck, they watch you shit, they watch when you pick your nose at the stop light or when you chew out the clerk at 7-11 over nothing or when you walk past the lady collecting for the women's shelter and you don't put anything in her jar. "They're even watching us right now," the hobo added and extended a grimy, gnarled digit to the small black orbs mounted at either end of the train car. There were some days when I loved taking public transportation, and other days when I didn't. On a good day, I liked to sit back and watch the show, study the rest of the passengers, read into their little ticks and mannerisms and body language, and try to guess at their back stories, giving them names and identities in my head. It was fun in a voyeuristic kind of way. And luckily, today was a good day. I watched the old Vietnamese woman with the cluster of plastic shopping bags gripped tightly in her hand like a cloud of tiny white bubbles. My eyes traced the deep lines grooving her face, and I wondered about the life that led her to this place. I watched the lonely businessman staring longingly across the aisle at the beautiful Mexican girl in the tight jeans standing with her back to him. He fidgeted with the gold band on his finger, and I couldn't tell if he was using it to remind himself of his commitment or if he was debating whether he should slyly slip it off and talk to her. According to the above context, answer the following question. The businessman is:
