  3. The NEC is more effective when jurisdictions adopt it as law.
  4. Amendments to the NEC are primarily made at local, not state, levels.
Enter to expand or collapse answer.Answer expanded
Option C is correct because when adopted into law by states and local jurisdictions, the NEC has a more real significance. Option A is incorrect because installation-code timing is different among locals. Option B is incorrect because different electrical codes are enforced across the United States. Option D is incorrect because the NEC can be adopted with both state and local amendments.

Competency 004—The Technology Education teacher knows how to plan, produce and manage a technology systems project.

4. A technology education class is planning the design and production of an all-in-one remote control for the home. The teacher wants the class to understand the importance of considering human factors in the project. Which of the following is the best first activity to assign the students?

Option A is correct because in order for students to begin considering design implications and use, they must first understand the principles of ergonomics, which studies how the interactions between humans and the elements of a system can optimize humans' well-being. Options B, C and D are incorrect because they should be introduced only after some foundational knowledge has been introduced and understood.

5. Designing a logo to accurately communicate a company’s message is an example of which of the following steps of the communication model?

  1. Encoding
  2. Transmitting
  3. Decoding
  4. Evaluating
Enter to expand or collapse answer.Answer expanded
Option A is correct because encoding is the process of translating an idea into symbols that receivers can understand. In this case, the logo is the visual symbol used to encode the company’s image. Option B is incorrect because transmission is the process of sending the message through various channels. In this case, transmission may occur when the logo is printed and distributed on a business card. Option C is incorrect because decoding is the processing stage in which the receiver interprets the message. In this case, decoding takes place when a customer sees the logo and forms an opinion about the company based on the logo. Option D is incorrect because evaluating is what happens at the end of the process to determine if receivers (customers) got the intended message.

Option B is correct because leaving white space focuses the viewer’s attention and gives the opportunity to take a break from all the information provided. Option A is incorrect because when fonts vary too much, it can be distracting and can disrupt the viewer's understanding. Option C is incorrect because colors provide emphasis but don’t necessarily help the viewer understand the intended message. Option D is incorrect because consistency of style must be used when creating a project, but it does not play as big a part in helping the viewer process information as white space does.

Competency 008—The Technology Education teacher demonstrates knowledge of video and audio systems (e.g., radio, television), production techniques (e.g., recording, editing) and equipment (e.g., amplifiers, video cameras).

  3. delaying approval while testing for long-term side effects.
  4. banning it for human consumption through legislation.
Enter to expand or collapse answer.Answer expanded
Option A is correct because the United States government has not to date established any regulations specific to bioengineered food. Option B is incorrect because labeling laws have been proposed, but none have been passed. Option C is incorrect because foods produced from genetically modified crops are not tested more than other foods. Option D is incorrect because not only are genetically modified crops not banned, but some sources estimate that up to 85 percent of United States corn is genetically engineered.
