GMAT Sentence Correction (SC) | Re: MODIFIER Set (700-800) Although covered in about 11 inches

10. In the original sentence, the modifier “whose eyes and noses are peaking out…”
incorrectly refers to “shallows.” When used to introduce a noun modifier, “whose”
always refers to the immediately preceding noun. In this case, the author intends to
refer to the “crocodiles,” not the “shallows.”
(A) This choice is incorrect as it repeats the original sentence.
(B) The modifier “whose eyes and noses peak out…” incorrectly refers to “shallows.”
When used to introduce a noun modifier, “whose” always refers to the immediately
preceding noun. In this case, the author intends to refer to the “crocodiles,” not the
“shallows.” Further, the past tense “encountered” is inconsistent with the present
tense “participate.” When there is no compelling reason to change tenses,
consistency is preferred. Also, the past tense “encountered” seems to imply that
these encounters have already happened. However, it is clear from the original
sentence that the encounters are ongoing occurrences for “vacationers who
participate in guided boat tours.”
