Expression of Ideas / Rhetorical Synthesis Difficulty: Medium

While researching a topic, a student has taken the following notes:

By interlocking their bodies, ants can form bridges to help fellow ants cross gaps.
In 2020, Yasemin Ozkan-Aydin was inspired by ant behavior to design collaborative quadruped robots.
Over the course of a year, she designed, built, tested, and refined her robots.
Each robot is programmed to send a signal to another robot upon encountering a gap in a path.
The signaled robot connects to the back of the signaler robot via magnetic sensors and pushes it across the gap.

The student wants to begin a narrative about the creation of the robots. Which choice most effectively uses relevant information from the notes to accomplish this goal?

When one of Yasemin Ozkan-Aydin’s robots encounters a gap in its path, it sends a signal to another robot; the signaled robot connects to the back of the signaler and pushes it across the gap.

After a year, Yasemin Ozkan-Aydin had designed, built, tested, and refined her robots.

Inspired by ants, which form bridges with their interlocked bodies to help fellow ants cross gaps, Yasemin Ozkan-Aydin set out to design quadruped robots capable of similarly collaborative behavior.

Ants, which have inspired the design of robots, form bridges by interlocking their bodies.

Explanation

Choice C is the best answer. The sentence effectively begins a narrative about the creation of the robots, explaining that ants’ gap-crossing technique inspired Yasemin Ozkan-Aydin to "set out to design" robots that could collaborate in a similar manner.

Choice A is incorrect. The sentence describes how the robots work together to cross gaps; it doesn’t effectively begin a narrative about the creation of the robots. Choice B is incorrect. The sentence provides an overview of the steps Ozkan-Aydin took in creating the robots; it doesn’t effectively begin a narrative about their creation. Choice D is incorrect. The sentence explains how ants form bridges; it doesn’t effectively begin a narrative about the creation of the robots.
