Quantitative Review, 2nd Ed, #154 of Data Sufficiency:
I've been seeing a lot of SC errors on non-SC sections of the OG. Here is an example:
"A survey of employers found that during 1993 employment costs rose 3.5 percent, where employment costs consist of salary cost and fringe benefit costs..."
Doesn't the sentence contain a modifier error? Shouldn't it be, "..3.5 percent, in which employment costs..?"
According to MGMAT SC Guide, we can only use "where" to modify places, while we can use "in which" to modify time (modifier chapter) and to modify places (idiom chapter of "where")
I've beens seeing a lot of similar SC errors (usually with respect to modifiers) in other sections (CR, RC, and Quant). Can someone shed light on this?
