I am a little bit confused by ambiguity with pronoun agreements and comparisons.
For example comparisons: "Grades for this semester are much lower than last semester" Apparently there is ambiguity because grades could be compared to semester. However, I have seen that such ambiguity is ruled out in other cases because such a comparison doesn't make sense.
For example pronouns: "When Norma and her husband read an article about Florida's adorable manatees, they promised each other that they would one day go to Florida and see one." Apparently "they" is not ambiguous and I believe this is the case because it doesn't make sense when it refers to manatees.
So my question is, does meaning matter when it comes to comparisons and pronoun agreement? If it is obvious that the sentence doesn't make sense when manatees go to Florida, can I dismiss this choice? I feel the Gmat isn't 100% clear on these two issues.
