Definitely a labyrinthine sentence
.
Best way to attack it is by finding the one or two words each answer choice (except the correct answer) that are faulty. Elimination will get us quickly (or at least relatively quickly
) to the correct answer:
The average human being can hear sounds of up to 20 kHz frequency; therefore, most of the sounds made by the tiny parts inside a computer — regardless of volume — are inaudible to the human ear, because their frequencies are often in the 100 kHz range — too high for the human ear to detect.
A.therefore, most of the sounds made by the tiny parts inside a computer — regardless of volume — are inaudible to the human ear, because their frequencies are often in the 100 kHz range — too high for the human ear to detect
B.therefore, because the frequency of the sounds made by the tiny parts inside a computer are often in the 100 kHz range,
that makes them inaudible to the human ear
C.therefore, the
frequencies of the tiny parts inside a computer—regardless of volume—often in the 100 kHz range, are inaudible to the human ear
Here the answer choice is implying that 'the tiny parts' have frequencies. It is the sound they generate that has a frequency.
D.most of the sounds made by the tiny parts inside a computer—regardless of volume—are therefore inaudible to a human being because of their frequencies
being too high for the human ear to detect them
E.most of the sounds made by the tiny parts inside a computer—regardless of volume—are often in the 100 kHz range
that is inaudible to the human ear
Need to use 'which' instead of 'that' because we are referring to all 100KHZ sounds.
