Question

selma made an error while creating a chart to describe the technological design process for a new vacuum.
technological design for a new vacuum cleaner

stage	description
evaluate the solution	create sketches of the vacuum cleaner prototypes
implement the solution	test the prototypes and evaluate their performance
design a solution	build a full - sized vacuum cleaner based on the best prototype results

which best describes how selma can correct the error in her chart?
change \identify a need\ to \identify a problem.\
switch the descriptions for \identify a need\ and \evaluate the solution.\
change \implement the solution\ to \test the prototype.\
switch the stages \evaluate the solution\ and \design a solution.\

Explanation:

In the technological design process, one first identifies a need, then designs a solution (like creating sketches of prototypes), then implements the solution (build a full - sized product based on prototype results), and finally evaluates the solution (test the prototypes and evaluate performance). Selma has the "Evaluate the solution" and "Design a solution" stages out of order.

Answer:

Switch the stages "Evaluate the solution" and "Design a solution."
