In this task, you will be shown a passage. You need to write a fill-in-the-gap question based on your understanding of the events that might be inferred from the passage. Your question should be answerable based on the passage and only have one correct answer. Show the gap in your question with a _ .

(CNN) A police report says that Venus Williams is responsible for a car accident earlier this month in Florida, which caused injuries to a 78-year-old man who later died. The Palm Beach Gardens Police report states the accident occurred on June 9 in Palm Beach Gardens and the victim, Jerome Barson, was a passenger in a car that was driven by his wife, Linda Barson. The victim's family has since filed a wrongful death lawsuit against Williams, alleging negligence. According to the suit, the impact of the crash caused damage to both vehicles. The Barsons' 2016 Hyundai Accent was "crushed, the front windshield shattered, the airbags deployed, there was crush damage to the rear on the driver's side, and the back window was shattered." Williams' 2010 Toyota Sequoia "was also severely damaged," the suit says.Venus Williams is responsible for a car accident that led to a fatality, according to a police reportThe victim's family files wrongful death suit against the tennis star

(CNN) -- X-ray data from NASA's MESSENGER probe points to high levels of magnesium and sulfur on the surface of the planet Mercury, suggesting its makeup is far different from that of other planets, scientists say. The unmanned orbiter has been beaming back data from the first planet for a year and a half. Readings from its X-ray spectrometer point to a planet whose northern volcanic plains formed through upwellings of rocks more exotic than those often found on the Earth, the Moon or Mars, said Shoshana Weider, a researcher at the Carnegie Institution of Washington. "Before this MESSENGER mission, a lot of people assumed it was very like the Moon -- it's dark, it's grey," Weider said. But while the Moon's surface formed when light materials floated to the top of an ocean of molten rock, the low level of calcium on Mercury indicates that didn't happen there.NASA probe gives insight into Mercury's formationThe surface has sulfur levels 10 times higher than Earth'sThe MESSENGER orbiter has been circling Mercury since March 2011

From Casinos in Las Vegas to museum facades, modern architects and engineers take inspiration from ancient structures such as the Great Pyramids and Parthenon. Now an infographic details some of the techniques used to build these inspirational and lasting monuments. It includes the eco-friendly Roman concrete and the Incas' ability to cut stone and slot pieces together like a jigsaw to build Machu Picchu. It also shares the latest thinking on how experts argue mysterious structures were made. Experts still debate about some feats of engineering, such as how vast stones were lifted into place to build the iconic pyramids at Giza.Infographic details techniques used to build inspirational monumentsIncludes Roman concrete, Greek geometry and Turkish cutting precisionSome mysteries are unsolved, including how stone was moved to build the pyramids and how the Incas created such sharp joins at Machu Picchu

But perhaps the reason why the testament to _ engineering has lasted so long is a secret concrete recipe, which experts are still trying to emulate today.
