Question

how do engineers and phone manufacturers use robots to improve the design of their touch screen phones?
a. robots design the majority of the touch screen features.

b. they use robots to repeat the exact same tests and refine a design.

c. robots can change the electric current running through a touch screen.

d. robots are good insulators, and therefore more accurate with touch
screens.

Explanation:

• Option A: Robots don't design most touch - screen features; engineers do the design work. So A is incorrect.
• Option B: In phone manufacturing, robots are used for repetitive testing (like stress - testing the touch - screen) to find flaws and refine the design. This is a common use of robots in manufacturing.
• Option C: Robots don't change the electric current in touch - screens. The current is determined by the circuit design. So C is incorrect.
• Option D: Robots are not used as insulators for touch - screens, and this statement misrepresents the role of robots in phone manufacturing. So D is incorrect.

Answer:

B. They use robots to repeat the exact same tests and refine a design.
