Difficulty: EasySequential Detail Extraction

To safely inspect and replace a vehicle's spark plugs, a technician must first disconnect the negative battery cable to eliminate the risk of electrical shock. Next, any debris surrounding the spark plug boot should be cleared with compressed air before removing the ignition coil. After unscrewing the old spark plug, the technician must verify the electrode gap on the replacement plug. Finally, the new spark plug is threaded into the cylinder head by hand before being torqued to manufacturer specifications.

According to the passage, which action should be taken immediately before removing the ignition coil?

  1. A
    Disconnect the negative battery cable
  2. B
    Verify the electrode gap on the replacement plug
  3. Clear debris around the spark plug boot with compressed airAnswer
  4. D
    Apply dielectric grease to the terminal connections

Answer

Clear debris around the spark plug boot with compressed air
The passage clearly specifies that clearing debris around the spark plug boot with compressed air must be completed before removing the ignition coil.

Step-by-Step Solution

1
Locate the mention of 'ignition coil' in the passage
Identified the sentence: 'Next, any debris surrounding the spark plug boot should be cleared with compressed air before removing the ignition coil.'
Locating the key landmark term from the question stem anchors the chronological search.
2
Analyze the temporal transition word 'before'
Recognized that clearing debris with compressed air is the prerequisite action performed prior to coil removal.
Sequential detail extraction requires identifying relative timing cues connecting adjacent steps.

Key Concept

Identifying immediate precursor steps using explicit chronological markers in procedural text.
