SC - broken records(Manhattan Flash Card Doubt)

[goelmohit2002]

Hi All,

In the Manhattan SC flash cards available at:

http://www.manhattangmat.com/pdf/FlashC ... e_2009.pdf

page#91....

the sentence given is
"Since 1973, the record was broken eight times due to technology that advanced even more rapidly than commentators have predicted."

Flash cards say the above is wrong....because

"Using "since" necessitates the present perfect ("has been broken") to indicate an action that continues to occur over time. Similarly, since records are still being broken, technology is likely still advancing (thus we must use "has advanced").
Because the commentators’ predictions occurred before the records were broken and are no longer in effect, the present perfect ("have predicted") is incorrect - past perfect or simple past must be used."

The same is corrected as

"Since 1973, the record has been broken eight times due to technology that has advanced even more rapidly than commentators had predicted (or simply "predicted")."


I have one doubt about the above explanation:

Can someone please tell why can't we have simple "advanced" instead of "has advanced"...why do we need "has advanced" to be necessarily there ?

Can Moderator please move this to "General Verbal or Manhattan Strategy guide forum"...

By mistake I posted on the GPrep folder.

Is there a mistake in usage of "due to"? Don't we have to use because of?

Thanks in advance!

yes, "due to" is used incorrectly.
