For those who had this question, it states (and I'm paraphrasing) that "Osmosis causes freshwater fish to gain water and marine fish to lose water. Which of the following is true?"
So, based on this, I determined before looking at the answer choices that freshwater fish must live in hypotonic water and marine fish live in hypertonic water (compared to their internal fluid). Seems sensible.
After reading the answer choices, I found two correct answers! The possible answers were
A. Marine fish live in an environment hypertonic to their body fluids.
B. Marine fish live in an environment hypotonic to their body fluids.
C. Freshwater fish live in an environment hypertonic to their body fluids.
D. Freshwater fish live in an environment hypotonic to their body fluids.
Now, based on the question, B and C are wrong and A and D are right. I can't see how there is only one answer for this question.
Am I going crazy?
BTW, I put down 'D' and the answer was 'A'. As far as I can tell they are both correct. Kaplan says flat out that D is incorrect.
