7th Grade ELA – Pre-test Assessment 4

1. Question

Part A

Which phrase is closest in meaning to the word deliberately as it is used in paragraph 3 of “Short Circuit”?

A. For the most part.
B. By general agreement.
C. With short notice.
D. With careful consideration.

2. Question

Part B

Which detail from “Short Circuit” provides the best clue to the meaning of the word deliberately?

A. “good conductor”
B. “not as good”
C. “chosen to”
D. “very low”

3. Question

Part A

Which sentence best states a central idea of “Short Circuit”?

A. Appliances can be destroyed by a heavy flow of electrons.
B. The flow of electrons follows a path of least resistance.
C. Fuses are an important means to keep homes safe from electrical hazards.
D. Circuit breakers are a tool to control the flow of electricity in homes.

4. Question

Part B

Which detail from the article provides the best example of the central idea in Part A?

A. “In a normal electric circuit, an electric current powers an appliance, such as a refrigerator or TV.”
B. “Every such appliance has a certain amount of resistance to the current flow, which keeps the current from reaching very large values.”
C. “Although houses today often contain circuit breakers rather than fuses, fuses are still around.”
D. “. . . the wire in the fuse heats up quickly and melts, breaking the circuit and preventing a fire from breaking out.”

5. Question

Part A

Which step of the experiment is repeated multiple times in “Short Circuit”?

A. Use an alligator clip to attach a copper wire to a battery terminal.
B. Attach one end of an iron wire to the other battery terminal.
C. Use a second alligator clip to attach the other end of the copper wire to the iron wire.
D. Shorten the distance between the second alligator clip and the battery.

6. Question

Part B

A result occurs when the step is repeated in the experiment. Which phrase from “Short Circuit” shows the result of the repeated step that is the answer to Part A?

A. “. . . deliberately chosen to have very low resistance.”
B. “. . . voltage of the battery pushes electrons through the circuit . . . .”
C. “. . . more current flows”
D. “. . . which keeps the current from reaching very large values.”

7. Question

Part A

Which paragraph best summarizes the conclusions of the experiment in “Short Circuit”?

A. Paragraph 2
B. Paragraph 3
C. Paragraph 4
D. Paragraph 5

8. Question

Part B

Identify three details from “Short Circuit” that provide the best summary of the conclusions in the experiment.

A. Most houses have circuit breakers.
B. Frayed wires can touch appliances.
C. Iron wire is a good conductor of electricity.
D. The length of a wire affects its resistance.
E. Electric current powers appliances.
F. A short circuit occurs when there is a high flow of current with low resistance.
G. Appliances can short-circuit, creating a fire hazard.
