Below are sample questions representative of the exercises included on this worksheet and related 7.68 Defining Problems with Criteria and Constraints skill assessments:

Problem 1Difficulty: Mastery

Which set best defines criteria and constraints?

ACriteria: contain oil. Constraints: must take more than 20 minutes; must use microplastic foam.

BCriteria: storage container ≤1.2 m; no microplastic foam. Constraints: contain oil; deploy fast.

CCriteria: contain oil in 10 m section for ≥3 hours in small waves; deployable by two people in <8 min. Constraints: storage container length ≤1.2 m; no foam that breaks into microplastics.

DCriteria: spread oil. Constraints: use crumbly foam; take 30 minutes to deploy; storage 3 m.

Solution & Explanation:Containment performance and deployment speed are criteria. Storage size and banned material are constraints.

Problem 2Difficulty: Mastery

Which option best identifies criteria and constraints?,A. Criteria: reduce odors. Constraints: must be taller than 1 m; must require lifting 15 kg. | B. Criteria: attract flies; block airflow. Constraints: any size; must lift 20 kg. | C. Criteria: limit odors; prevent flies; allow airflow for composting. Constraints: fit under 45 cm clearance; emptying requires lifting ≤8 kg at a time. | D. Criteria: fit under 45 cm clearance; lifting ≤8 kg. Constraints: limit odors; prevent flies; allow airflow.,C,Odor control

Solution & Explanation:answer choices

Problem 3Difficulty: Mastery

Which set best defines criteria and constraints?

ACriteria: stay cooler. Constraints: must not fit chains; must include banned chemicals.

BCriteria: stay ≥10°C cooler than black rubber; resist cracking for 3 years; no sharp edges. Constraints: attach to existing chains; materials must meet chemical safety regulation.

CCriteria: be hotter; crack quickly. Constraints: ignore chemical regulations; use any attachment.

DCriteria: attach to existing chains; meet chemical regulation. Constraints: stay cooler; resist cracking; be safe.

Solution & Explanation:Cooling, durability, and safety are criteria. Chain compatibility and chemical regulations are constraints.
