Zorluk: OrtaSequential Detail Extraction

During field repairs of carbon-fiber aircraft panels, technicians follow a strict thermal curing sequence. First, the damaged area is sanded down to bare composite and wiped clean with solvent. Next, a pre-impregnated resin patch is applied over the repair zone. Prior to activating the heating blanket, technicians must install a vacuum debulking bag over the patch to eliminate trapped air pockets. Once the vacuum seal achieves the required pressure, the heating cycle is initiated to cure the resin. Finally, after the assembly cools to ambient temperature, the vacuum bag is removed for ultrasonic inspection.

According to the passage, which action is performed immediately prior to activating the heating blanket?

  1. A
    Wiping the sanded surface clean with solvent
  2. Installing a vacuum debulking bag over the patchCevap
  3. C
    Removing the vacuum bag for ultrasonic inspection
  4. D
    Allowing the composite assembly to cool to ambient temperature

Cevap

Installing a vacuum debulking bag over the patch
The passage clearly establishes the order of operations by stating that prior to activating the heating blanket, technicians must install a vacuum debulking bag over the patch to remove air pockets.

Adım Adım Çözüm

1
Locate the target trigger event in the passage
Identified the phrase 'Prior to activating the heating blanket'
The question asks for the action performed immediately before the heating blanket is activated.
2
Extract the procedural action directly linked to the temporal preposition 'prior to'
Found 'technicians must install a vacuum debulking bag over the patch to eliminate trapped air pockets'
The cue 'prior to' explicitly establishes that installing the vacuum bag precedes blanket activation.
3
Match the extracted action to the corresponding answer choice
Selected the choice stating 'Installing a vacuum debulking bag over the patch'
This directly restates the exact preparatory step described in the passage.
