When engineers design a part for a machine, the design is passed on to the factory where the part will be produced. Depending on what the part will be used for, the engineers specify the extent to which the finished factory part must match the exact dimensions called for in the design. Design criteria that require the finished part to strictly match design specifications would most likely be necessary when the part must:
  1. Be mass-produced cheaply and in large quantities.
  2. Last for a long period of time before needing to be repaired or replaced.
  3. Be able to withstand high levels of stress during frequent use.
  4. Interact with other precision parts in a final product.

Student teams in a science class are determining the amount of salt that can be dissolved in water at 10°C, 25°C, and 40°C. The teacher has asked the students to use three different beakers for making the measurements and then repeat the series of experiments a second time. The primary reason for having the students do the series of experiments twice is to:
  1. Improve the reliability of the results of the investigation.
  2. Create a reference set of data that serves as a control.
  3. Remove the potential for human error.
  4. Provide an opportunity to practice the procedure.
