i-Ready - Using Details to Explain Ideas in an Informational Text

Newer ocean-exploring robots like SoFi are remotely controlled and don't require a cable connection to a ship.
SoFi's parts were largely produced using 3D printers making her easier and cheaper to manufacture compared to earlier ocean robots.
The implication is that future SoFi copies can be produced even more simply and rapidly.
Rus envisions releasing "schools" of SoFis into the ocean to gather vital information about marine life.
Examples, such as the soft-robotics team at MIT testing the robot, are provided.

SoFi's mission has been successful based on initial tests.
During testing among coral reefs in the South Pacific Ocean, schools of fish swam very close to SoFi, essentially ignoring her.
This blending ability may one day contribute to saving ocean habitats and the marine life within them.
