Question

1. what is a common example of using reverse engineering to solve a problem?

determining if a train derailment was the result of faulty equipment
taking apart a generator to build a small battery
using the blueprints for an aircraft to design a safer runway
using a sandpaper - based power tool, designed for wood, to grind down a dog’s toenails

Explanation:

Reverse engineering involves deconstructing a product or system to understand its design, function, or root cause of a failure. Analyzing a train derailment by examining equipment to find if a fault caused it is a reverse engineering process—working backward from the problem (derailment) to identify the source (faulty equipment) by investigating the system. The other options do not fit: taking apart a generator to build a battery is repurposing, using aircraft blueprints for runways is unrelated cross-design, and repurposing a wood tool for pet care is not reverse engineering.

Answer:
