Whales originated in the freshwater lakes and rivers of ancient Asia about sixty million years ago. Not until about ten million years later did species of whales develop specialized kidneys enabling them to drink salt water. Although fossil evidence shows that some early whale species that lacked such kidneys sometimes swam in the Earth’s saltwater oceans, these species must have had to return frequently to freshwater rivers to drink. Which of the following is most strongly supported by the information given? A. Fossils of whale species dating from between sixty million and fifty million years ago will not be found on continents that were at the time separated from ancient Asia by wide expanses of ocean. B. Among whale fossils that date from later than about fifty million years ago, none are fossils of whale species that drank only fresh water. C. Fossils of whale species that drank fresh water will not be found in close proximity to fossils of whale species that drank salt water. D. The earliest whales that drank salt water differed from fresh-water-drinking whales only in their possession of specialized kidneys. E. Between sixty million and fifty million years ago, the freshwater lakes and rivers in which whales originated were gradually invaded by salt water.

A. Fossils of whale species dating from between sixty million and fifty million years ago will not be found on continents that were at the time separated from ancient Asia by wide expanses of ocean. Eliminate: Too strong. "Will not be found". Traders could have caught whales, dragged them on board, and taken them to another location. B. Among whale fossils that date from later than about fifty million years ago, none are fossils of whale species that drank only fresh water. My choice. I believe later than fifty million years ago means 49, 48.... This would mean that all whales possessed the specialized kidneys. C. Fossils of whale species that drank fresh water will not be found in close proximity to fossils of whale species that drank salt water. Eliminate: Too strong. "Will not be found". A whale fresh water whale could have died and its body could have drifted to the salt water whale location(s). D. The earliest whales that drank salt water differed from fresh-water-drinking whales only in their possession of specialized kidneys. Eliminate: Too strong. "Only" What if they were smaller? What if they had bigger teeth? We can't make a prediction this broad. E. Between sixty million and fifty million years ago, the freshwater lakes and rivers in which whales originated were gradually invaded by salt water. Eliminate: We don't know what invaded what. Moreover, we're discussing whales.
A. Fossils of whale species dating from between sixty million and fifty million years ago will not be found on continents that were at the time separated from ancient Asia by wide expanses of ocean. Hold B. Among whale fossils that date from later than about fifty million years ago, none are fossils of whale species that drank only fresh water. later than 50 mio years include current whales, which have the special kidney C. Fossils of whale species that drank fresh water will not be found in close proximity to fossils of whale species that drank salt water. the evolution means that whales with the special kidney and whales without that kidney should meet on time D. The earliest whales that drank salt water differed from fresh-water-drinking whales only in their possession of specialized kidneys. for me, the reason to discard this answer is the word "only" aren't there any other differences? E. Between sixty million and fifty million years ago, the freshwater lakes and rivers in which whales originated were gradually invaded by salt water. this is not the matter
A. Fossils of whale species dating from between sixty million and fifty million years ago will not be found on continents that were at the time separated from ancient Asia by wide expanses of ocean. Hold

How can you hold without any reason? Seems the question is ridiculously complicate.
If whales did not have the type of kidneys required to process the saltwater, then they cannot be found in the continents that were seperated from ASIA as the whales cannot cross the wide gap (i.e. full of saltwater) between the continents..
The stimulus says: these species must have had to return frequently to freshwater rivers to drink.
(A) says :
Fossils of whale species dating from between sixty million and fifty million years ago will not be found on continents that were at the time separated from ancient Asia by wide expanses of ocean.
If continents were separated by big oceans how can whales return to drink fresh water ?

Hi GMAT Tiger,
for me it's clear:
because at that time whales weren't able to cross seas and because they originated in Asia, fossils cannot be found in other part but in Asia
Whales originated >>-where->> in ancient Asia about sixty (60 million years ago) species of whales (Asia/which continent dont know) develop spl salt water kidneys (50 million years ago). Although fossil evidence >>says>>> (species - kidneys) sometimes swam in the Earth’s saltwater oceans (not of Asia as Asia has fresh water), these species must have had to return (return means they travelled back) to drink.
means, kidney -minus whales of salt water (not Asia) went to freshwater (in Asia) ..this is saying that it did cross..

Can a CR expert please validate and reason the answer A. Please help me understand the various parts of this passage: what is the conclusion, assumption of the passage and what are we trying to support from the options? Thanks.
