"NASA’s First Planetary Defense Technology Demonstration to Collide with Asteroid in 2022" by Justyna Surowiec Structure is essential to the equation; in Didymos, researchers aren’t sure whether DART will impact an asteroid composed of solid rock, loose rubble or something “softer,” more akin to sand. A softer surface would absorb more of DART’s force and may not be pushed as drastically as if DART hit a harder surface. Extensive modeling and simulation, part of a large international campaign that started in 2014, is being done in conjunction with Lawrence Livermore National Laboratory and other members of the investigation team to help researchers predict what will happen to DART’s target after impact. They’ve considered these various factors—along with the added momentum from DART’s impact and the resulting debris ejected from the crater it creates – as they’ve run various simulations. These simulations help the team shape its expectations for impact. NASA’s First Planetary Defense Technology Demonstration to Collide with Asteroid in 2022, NASA, May 6, 2019 Question Use the passage from “NASA’s First Planetary Defense Technology Demonstration to Collide with Asteroid in 2022” and the video to answer the question.

The most appropriate response to the question regarding a limitation of the article compared to the video is:
It lacks visuals that show the DART simulations.
This option highlights that the article does not include visual aids, which can enhance understanding and provide a clearer representation of the DART simulations discussed in the text.
