Question

the passage below describes how the engineering - design process was used to test a solution to a problem. read the passage. then answer the question below.
kaylee planned to build a large, wooden skateboard ramp. she wanted the finished ramp to have a base, sides, and supports for stability. also, she didnt want the ramp to be too steep for her friend shane, who was a beginning skateboarder. so, before she built the ramp, she made a prototype by propping up a flat piece of plywood on a 3 ft high stack of bricks. shane skated down the prototype ramp. then, they discussed how steep the ride was.
which of the following could kaylee and shanes test show?
how much wood kaylee would need to build the finished 3 ft high ramp
if a 3 ft high ramp would be steep enough for advanced skateboarders
whether shane thought a 3 ft high ramp would be too steep for him

Explanation:

• The first option is incorrect because the test with the prototype (using a plywood and bricks) doesn't involve measuring or determining the amount of wood needed for the final ramp.
• The second option is incorrect as the test was done with Shane, a beginning skateboarder, not advanced ones, so it can't show if it's steep enough for advanced skateboarders.
• The third option is correct because Shane, a beginning skateboarder, skated down the prototype (3 ft high) and they discussed how steep the ride was, so this test can show whether Shane thought the 3 ft high ramp was too steep for him.

Answer:

whether Shane thought a 3 ft high ramp would be too steep for him
