Question

newer ocean - exploring robots, like sofi, are controlled from far away and do not need a cable - to - ship connection.
many of her parts were made by 3 - printers, so sofi was easier and cheaper to make than ocean robots. this means that making copies of sofi in the future should be even simpler and faster. rus hopes scientists will someday release schools of sofis into the seas to collect important information about ocean life.
so far, sofis mission has been a success. when the soft - robotics team at mit tested her among coral reefs in the south pacific ocean, schools of fish swam within inches of sofi, completely ignoring her. who knows? maybe one day sofis ability to blend in will help save ocean habitats and the plants and animals that live in them.
which detail supports the idea that sofis mission has been a success? drag the detail to the chart.
idea
sofis mission has been a success.
detail

Explanation:

The text states that when the soft - robotics team at MIT tested SoFi among coral reefs in the South Pacific Ocean, schools of fish swam within inches of SoFi, completely ignoring her. This shows that SoFi was able to blend in well with the ocean environment, which is an indication of the success of its mission.

Answer:

When the soft - robotics team at MIT tested her among coral reefs in the South Pacific Ocean, schools of fish swam within inches of SoFi, completely ignoring her.
