Text from PassageAnalysis
"When moisture infiltrates audio equipment, crackling and distorted playback typically result."
  • What it says: moisture in audio equipment causes crackling and distorted sound
  • What it does: Establishes the problem that moisture creates in audio equipment
  • What it is: Context/problem statement
[MISSING WORD/PHRASE]
  • What it is: Missing logical connector
"equipment, by comparison, produces clean, undistorted sound quality."
  • What it says: different equipment produces clean, undistorted sound
  • What it does: Contrasts with the moisture-damaged equipment problem
  • What it is: Contrasting statement

Provide Passage Architecture & Core Elements

Main Point: The passage contrasts equipment that produces poor sound quality due to moisture damage with equipment that produces clean, high-quality sound.

Argument Flow: The passage sets up a simple comparison structure - first presenting the negative effects of moisture on audio equipment, then contrasting that with equipment that doesn't have these sound quality problems.

Step 2: Interpret the Question Precisely

This is a fill-in-the-blank question asking us to choose the best logical connector. The answer must create the right relationship between what comes before and after the blank.

Step 3: Prethink the Answer

  • The missing word needs to describe equipment that logically contrasts with moisture-damaged equipment
  • Since moisture infiltration causes problems, we need equipment that doesn't have these problems - equipment that works properly
  • The word should describe the operational state of equipment, creating a clear cause-and-effect contrast
Answer Choices Explained
A

functioning

✓ Correct
  • Creates the perfect logical contrast between functioning equipment vs. moisture-damaged equipment
  • Directly explains why the sound quality would be clean and undistorted
B

expensive

✗ Incorrect
  • Cost has no logical relationship to moisture damage or sound quality
  • Expensive equipment can still be damaged by moisture
C

portable

✗ Incorrect
  • Portability is unrelated to the moisture/sound quality issue
  • Portable equipment can also be damaged by moisture
D

sensitive

✗ Incorrect
  • Creates confusion rather than clarity - sensitive equipment might be MORE susceptible to moisture damage, going against the intended contrast
