Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.

    It was one of the greatest art thefts in history. In March 1990, two thieves stole 13 pieces of art from the Isabella Stewart Gardner Museum in Boston. Valued at $500 million, it was the largest private art theft ever, and for decades, it has gone unsolved.

   The Isabella Stewart Gardner Museum is unique in the art world. Founded in 1903, it is the only museum where the art and the building are part of one person's private collection. Gardner was a collector of art who acquired many pieces on her travels to Europe. She eventually opened her museum to the public so she could share her art with the world.

   Two thieves disguised as police officers knocked on the museum's door late at night on St. Patrick's Day. Because of the holiday, there were festivities all over the city. The "police officers" told the two guards that there was a problem outside. Once inside, one of the "police officers" looked at the guards. "I have an arrest warrant for you," he said. That's when he put handcuffs on the guards.

    The thieves stole art from all over the museum. During the robbery, they set off an alarm when they tried to take a Rembrandt off a wall, but they quickly smashed it. The thieves finally left the museum 81 minutes later with their stolen art. The stolen art included The storm on the Sea of Galilœ by Rembrandt, Landscape with an Obelisk by Flinck, La Sortie de Pesage by Degas, and The Concert by Vermeer. The next morning, workers found the art gone and the guards still tied up. They immediately called in the police and an investigation began.

    Some called the robbery "dumb" because paintings are notoriously hard to sell, but others claimed the thieves were very professional. They weren't art experts and had likely been paid to steal the art. Today, the art has still not been found. Empty frames hang where the paintings were. They are reminders of what was stolen.  (Adapted from "Subject Link L8")
