Context: KEY WEST, with its scattering of 19th-century wooden homes, is one of the few places in Florida where an 80-year-old building isn't far and away the most ancient manmade structure in town. Even so, the La Concha Hotel, built in 1925, is certainly the largest historical building on the island that's still being used for its original purpose. At all of seven stories, it would scarcely qualify as a boutique hotel in a big city, but for this island it served as a skyscraper. The three of them walked into the marble-floored lobby, instantly chilled by the hotel's powerful air-conditioning (one of many post-1920s updates in the building, along with the computer reservation system and the Starbucks franchise). Winston peered around the crowded room, focusing in particular on a tall, gaunt man wearing a black suit and top hat and carrying a gnarled wooden cane. The dark stranger was ushering a gaggle of camera-wielding tourists out the side door and into the hotel's driveway. "Ghost Tour," Paul explained to Winston. "They walk around town, and the guide tells tales. It's fun." "It does sound interesting," said Winston, chuckling. "We've been trying to get a piece of that," said Chloe, "But the owners are pretty stubborn. It would be a nice compliment to Paul's fake séance racket." "You perform fake séances?" Winston asked Paul. "Not unless I have to, no. But I... what's the word... oversee a couple who do. Sometimes I step in and lend a hand if one of them is sick." In fact, Paul had written the original scripts and come up with the gags and tricks the performers used to put on their little show. Once he'd perfected it, he'd recruited two actors to do the nightly ritual and handle all the details. It provided a small but steady revenue stream for the Crew, and their hidden cameras sometimes picked up other useful information as well. Question: Who oversees the seances? Options:  A. not enough information  B. Winston  C. Chloe  D. Paul

Context: SEOUL — Arms control experts estimate that the dismantlement of North Korea’s nuclear program could take a decade to complete, and cost $20 billion, if a nuclear agreement is reached between U.S. President Donald Trump and North Korean leader Kim Jong Un when they meet in Singapore on June 12. “The hard work has not yet begun, and it is gong to take sustained energy on the part of the United States, South Korea, Japan, China and North Korea. It’s going to be a multiyear long process,” said Daryl Kimball, the executive director of the Arms Control Association in Washington. President Trump has said he expects a "very positive result" from the North Korea nuclear summit, but he also said it will likely be the beginning of a process to resolve differences over the extent of the North’s denuclearization, and the specifics regarding what sanctions relief, economic aid and security guarantees would be offered in return. U.S. Defense Secretary Jim Mattis said on Sunday that North Korea would only receive sanctions relief after it takes "verifiable and irreversible steps to denuclearization." This position aligns closer to the Kim government’s stance that denuclearization measures and concessions be matched action for action. And it backs away from demands made by some in the president’s national security team that Pyongyang quickly and unilaterally dismantle all its weapons of mass destruction before any concessions would be offered. North Korea is estimated to have 20 to 80 nuclear warheads, both known and covert nuclear research and processing sites, and thousands of ballistic missiles that can be launched from mobile vehicles, and submarine based launchers have been tested in recent years. With such an extensive nuclear arsenal it could cost $20 billion to achieve the U.S. goal of complete, irreversible, and verifiable nuclear dismantlement (CVID), according to a recent study conducted by Kwon Hyuk-chul, a Kookmin University professor of security strategy. Kwon based his assessment in part on past nuclear deals... Question: The denuclearization process will probably take Options:  A. a year  B. not enough information  C. a decade  D. a second

Read the following context and choose the correct option to answer the question. Context: April 1, 2006 Walter died today. Found out this morning over breakfast. Suicide. Walter. I'm still trying to wrap my mind around it. Suicide. Walter wasn't suicidal. I know that, know it for a fact. But he is dead. Why? I am not foolish enough to suspect "foul play" as they say in the mystery stories. No one cares enough about a community college art teacher to murder him. But suicide? Something is wrong here. Very wrong. April 2, 2006 I didn't realize until this morning that yesterday was April Fools day. Some kind of sick joke? But that's not like Walter either. He was a little crazy, but not that kind of crazy. Still I keep half expecting to pick up my voice and hear his voice yell, "Gotcha!" But it is no joke. I know he is dead. (Later) Got a package today. From Walter. Scary considering what I wrote about expecting him to call. I can't express the chill I got when I saw his name on the label. A message from the dead. Surely it's not a good Omen. It's a painting. Or at least I think it is. The package is the right shape, and knowing Walter it seems likely, but...I haven't yet worked up the courage to open it yet. I'm afraid of what I might find. April 3, 2006 Went to the funeral today. Walter's wife, Martha, was in hysterics. Can't say I blame her. It was awkward being there seeing someone in the most vulnerable possible condition. I didn't know her that well. Walter and I rarely interacted outside of work, so I have very little knowledge of his personal life. Sylvia went up to her and hugged her even though she'd never met her before in her life. It must be something with women to be able to make that kind of spontaneous connection. I just shook her hand, and told her I was sorry. I don't make a habit of crying in public, but seeing her so shaken up brought tears to the edges of my eyes, and I did nothing to wipe them away. After five years of friendship it's the least Walter deserves of me. One other thing. The package. It's still sitting there in my study. Mocking me. That's how it feels anyway. Should... Question: Why was Martha in hysterics? Options:  A. Her husband Walter died.  B. Her dog died.  C. not enough information  D. She got into a car accident.
