Question

1.3.2 test (cst): science and engineering
question 8 of 25
an engineer is designing an irrigation system for a farm. which statement describes the clearest constraint that applies to the solution?
a. it must deliver 5 liters of water per minute when in use.
b. it must provide water to certain areas of the farm.
c. it must comply with local regulations on irrigation systems.
d. it can use water from an existing well.

Explanation:

To determine the clearest constraint, we analyze each option:

• Option A: A specific flow rate (5 liters per minute) is a clear, measurable technical constraint for the irrigation system's design.
• Option B: "Certain areas" is vague and doesn't define a clear constraint.
• Option C: Local regulations are a broad category and not as specific a design constraint as a technical requirement like flow rate.
• Option D: Using an existing well is an option, not a constraint.

So, the clearest constraint is the specific flow rate requirement.

Answer:

A. It must deliver 5 liters of water per minute when in use.
