NOT A PROBLEM: Person A: I was really surprised to learn that your mum used to live in Wales. Person B: My mum? No, she never did that. You must be thinking of someone else. Person A: No, I’m not. I told her how my parents are from Cardiff and she said she’d lived in Newport until she was 18. Person B: She did not. Person A: Yes, she did. Person B: Nope. She’d have told me. Person A: Well, where do you think she grew up, then? Person B: In Yorkshire, of course. Like the rest of us. Person A: You’re wrong, you know. Person B: Bet I’m not. Person A: OK, well, I’m going to phone her and ask her. You’ll see. PROBLEM: Person C: You still have my Kindle. Person D: I do not. I gave it back to you two weeks ago. Person C: No, you didn’t. You said you were going to, but you never actually gave it to me. Person D: I did. I remember. It was when we were having lunch in Starbucks. Person C: No, that’s when you said you’d left it in your car and would get it when we’d finished eating but then you forgot all about it. Person D: Look, I gave it back to you. I think you’re just trying to get a new Kindle out of me, and let me tell you: it ain’t gonna work. Person C: You’re just trying to keep my Kindle for yourself. Well, I’m not going to let you get away with it. I’m going to tell your mum, so there. It really depends whether the parents are in a position to shed any light on the contentious issue or if involving them would just make an awkward situation worse. If parental input will be helpful, welcome the chance to confer with them; if it won’t, let the other person do what they will and trust your parents to have more sense than to get involved in a purely private argument. What is probably true about person B's feelings toward person A after the story? - Person B is excited that Person A called his mum. - Person B is glad Person A called his mum. - Person B is upset with person A for calling his mum. - not enough information

In 1981, when I was nine years old, my father took me to see Raiders of the Lost Ark. Although I had to squint my eyes during some of the scary scenes, I loved it – in particular because I was fairly sure that Harrison Ford’s character was based on my dad. My father was a palaeontologist at the University of Chicago, and I’d gone on several field trips with him to the Rocky Mountains, where he seemed to transform into a rock-hammer-wielding superhero. That illusion was shattered some years later when I figured out what he actually did: far from spending his time climbing dangerous cliffs and digging up dinosaurs, Jack Sepkoski spent most of his career in front of a computer, building what would become the first comprehensive database on the fossil record of life. The analysis that he and his colleagues performed revealed new understandings of phenomena such as diversification and extinction, and changed the way that palaeontologists work. But he was about as different from Indiana Jones as you can get. The intertwining tales of my father and his discipline contain lessons for the current era of algorithmic analysis and artificial intelligence (AI), and points to the value-laden way in which we “see” data. My dad was part of a group of innovators in palaeontology who identified as “palaeobiologists” – meaning that they approached their science not as a branch of geology, but rather as the study of the biology and evolution of past life. Since Charles Darwin’s time, palaeontology – especially the study of the marine invertebrates that make up most of the record – involved descriptive tasks such as classifying or correlating fossils with layers of the Earth (known as stratigraphy). Some invertebrate palaeontologists studied evolution, too, but often these studies were regarded by evolutionary biologists and geneticists as little more than “stamp collecting”.

SEOUL — North Korea’s sudden threat to pull out of the upcoming summit with the U.S. raises new doubts of whether a denuclearization deal is possible. North Korean leader Kim Jong Un agreed to meet with U.S President Donald Trump in Singapore on June 12 to work out an agreement to end the North’s nuclear program in exchange for security guarantees and an end to punishing international sanctions. But on Wednesday North Korea’s Vice Foreign Minister Kim Kye Kwan released a statement through the state-run KCNA news agency that criticized “unbridled remarks” made specifically by the U.S. president’s National Security Adviser John Bolton demanding that Pyongyang completely decommission its entire nuclear arsenal, along with its ballistic missile program and chemical weapons stockpile, before receiving any compensation or concessions. He expressed “indignation” at the U.S uncompromising position and said North Korea might pull out of the Trump-Kim summit, unless the Trump administration acts with “sincerity” to improve relations through dialogue. “If the United States is trying to drive us into a corner to force our unilateral nuclear abandonment, we will no longer be interested in such dialogue and cannot but reconsider our proceeding to the North Korea-U.S. summit,” the statement said. The vice foreign minister also said it was “absolutely absurd” that Bolton would compare Libya’s experience dismantling its relatively rudimentary nuclear program as a model for dealing with the North’s more advanced and expansive capabilities. He also denounced the Trump administration for “miscalculating the magnanimity” of Kim Jong Un’s decision to suspend further nuclear and missile tests, and his willingness to engage in nuclear talks, as “signs of weakness,” that were the result of what the U.S. administration has dubbed its “maximum pressure” campaign that led international efforts to impose punishing sanctions banning 90% of North Korean trade.
