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.

can we use because and therefore in the same sentence, are they not redundant?
regardless of volume, seems to modify tiny parts inside a computer
I chose E, but A is better logically. But A as well has problems.

I choose choice A because I do not see any error in this sentence. however, I will stand on a little to explain why other choice is wrong.

This is an interesting problem. I thought A was fine but read each of the remaining options. If I were to go with either, it would be D or E. D has missing info and E seems to slightly change the sentence.

i pick A here. does gmat test solely on punctuation??? even though other options have minor error. but i think punctuation is the major error in this SC

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.

Wrong usage of the modifier
Is the usage of "their" correct in the answer choice A . I would assume that "its" would be more appropriate.
When do we choose "they" and when do we choose "it".

IMO A is the correct answer. A sounds correct. B.."therefore, because" use make this a wrong choice C..it is the sound which is in some X frequency range is inaudible and not the frequency itself D..use of therefore at wrong place and use of being make this incorrect. E..presence of conclusive word would have made it more clear and use of that is not good.

Thanks Mazerath
Hey Mazerath,
They, Them ,Their are plural. It and It's are singular.
In A, their logically refers to "sounds" so we need to use a plural pronoun "their"
Also guys I was just wondering, the part that is not underlined: The average human being can hear sounds of up to 20 kHz frequency seems awkward to me. Why would you say 20kHz frequency, its like saying The car can accelerate to 100mi/h speed in ten seconds? Just a thought...

Sorry, it is definitely NOT a rule that you need a "therefore" after the semicolon! The only rule you really need to worry about in this situation: semicolons need to separate two independent clauses. And sure, "therefore" COULD be part of an independent clause, but it certainly isn't necessary. More on GMAT's treatment of punctuation in this video.

I hope this helps!
Hi Actually I eliminated all options with "Therefore". I though independent clauses cannot start with "therefore". Can you please provide some examples where "therefore" is a be part of an independent clause.
