Multiple Choice

Why is it important to understand the concept of contradiction (모순) in technological systems?

• Because it helps in identifying and solving conflicting requirements in product design

• Because it makes products more expensive

• Because it reduces the need for innovation

• Because it only applies to wearable devices
