Physics · Imaging and X-ray Tomography
Which choice most logically completes the text? To better understand the burrowing habits of Alpheus bellulus (the tiger pistol shrimp), some studies have used resin casting to obtain precise measurements of the shrimps' burrows. Resin casting involves completely filling an empty burrow with a liquid plastic that hardens to create a three-dimensional model; however, recovering the model inevitably requires destroying the burrow. In their 2022 study, Miyu Umehara and colleagues discovered that an x-ray computed tomography (CT) scanner can accurately record a burrow's measurements both at a moment in time and throughout the entire burrow-building process, something that's impossible with resin casting because ______

- 1the process of recovering the model distorts the resin's shape.
- 2the casting process takes more time than A. bellulus takes to construct a burrow.
- 3it does not allow for multiple castings of the same burrow over time.✓
- 4it can only be used on burrows below a certain size.
Correct answer
it does not allow for multiple castings of the same burrow over time.
