using details to explain ideas in an informational text - instruction - level e
what did daniela rus and her
team need most from sofi?
they needed sofi to be named for a
\soft robotic fish.\
they needed sofi to be constructed
from soft materials.
they needed sofi to fit in with the
underwater environment.
rus, who directs the computer science lab at mit,
robots like sofi may offer solutions to these
sofi (which is short for \soft robotic fish\), rus and
am wanted to create an undersea explorer that
fit right in with her environment. in other words,
eeeded sofi to look as fishlike as possible. so they

ned sofi to act like a fish. her size, shape, and
ry surface allow her to swim close to delicate ocean
ler flexible tail swishes smoothly from side to side, like
fish. it moves her forward and creates no more
ment than the tail of any other fish.

Explanation:

The text mentions that Rus and her team wanted to create an undersea explorer that "fit right in with her environment" and "needed SoFi to look as fishlike as possible". This indicates that fitting in with the underwater environment was the key need. The name - related option is just about the abbreviation, not the functional need. The material option is part of the field they work in (soft robotics) but not the main need for SoFi in terms of its role as an undersea explorer.

Answer:

They needed SoFi to fit in with the underwater environment.
