GMAT CLUB OLYMPICS: David: Humans did not evolve from an aquatic ances

Describe to argument question.

A) agreeing with him but adding counterarguments from opponents of that view. Lynn is also an opponent of that view as is apparent from her usage of 'but'.
(B) conceding that his evidence is valid but drawing attention to other evidence that refutes his argument. - Spot on. She agrees with David's evidence but provides additional evidence that takes an opposite turn from David's argument.
(C) initially agreeing with him but then changing her mind by drawing upon comparisons. Definitely didn't change her mind in the process. Incorrect.
(D) ignoring it and attacking the implications of his facts to support her counterargument. Lynn doesn't ignore David.
(E) acknowledging the facts he uses to support his argument but offering additional information to consider without herself making a conclusion. The runner-up IMO. Lynn definitely has a conclusion as is apparent from her usage of 'but'.

Lynn responds to David’s argument by

(A) Nothing related to views of opponents. Incorrect.
(B) Correct
(C) Didn't change her mind. Just agreed to the facts presented. Incorrect.
(D) She didnt ignore them. Incorrect.
(E) She refutes the conclusion made David but presenting counter. Incorrect.

IMO OA should be E.

Lynn says agrees with David's argument by saying 'True'. So, reject D

Lynn introduces additional facts and starts the sentence by 'but' and goes on to say that humans are unique in the animal kingdom.

Let's go by the options-


(A) agreeing with him but adding counterarguments from opponents of that view..............agreeing is correct but counterarguments from opponents is not correct. He is offering additional information

(B) conceding that his evidence is valid but drawing attention to other evidence that refutes his argument.............conceding is strong word. Reject it.

(C) initially agreeing with him but then changing her mind by drawing upon comparisons...................No comparison. Reject it

(D) ignoring it and attacking the implications of his facts to support her counterargument..................Not ignoring. Reject it.

(E) acknowledging the facts he uses to support his argument but offering additional information to consider without herself making a conclusion.......................Looks fine

Option E.

(A) agreeing with him but adding counterarguments from opponents of that view. = Lynn agrees to David initially but also draws his attention to the evidence which was provided of the fat skin. Incorrect usage.
(B) conceding that his evidence is valid but drawing attention to other evidence that refutes his argument. = He doesn't concede that argument is valid but acknowledges and then gives additional information. Incorrect usage.
(C) initially agreeing with him but then changing her mind by drawing upon comparisons. = Lynn doesnt change her mind. Incorrect usage.
(D) ignoring it and attacking the implications of his facts to support her counterargument. = Lynn doesnt ignore and attack. incorrect usage.
(E) acknowledging the facts he uses to support his argument but offering additional information to consider without herself making a conclusion. = Correct usage. he acknowledges and adds an extra information without concluding that ma evolved from aquatic species or not.

conclusion of David ; Humans did not evolve from an aquatic ancestor.
conclusion of Lynn:
we also have a layer of fat under our skin, which would make us unique in the animal kingdom as the only non-aquatic species that has evolved such fat, not to mention that fatty tissue is 90 percent as dense as water that would be useless outside of water.

Lynn responds to David’s argument by


(A) agreeing with him but adding counterarguments from opponents of that view. ; yes Lynn is agreeing but he is not adding any counter argument
(B) conceding that his evidence is valid but drawing attention to other evidence that refutes his argument. ; Lynn explaination does not refute David argument
(C) initially agreeing with him but then changing her mind by drawing upon comparisons. ; no comparison is drawn by Lynn
(D) ignoring it and attacking the implications of his facts to support her counterargument. ; irrelevant option
(E) acknowledging the facts he uses to support his argument but offering additional information to consider without herself making a conclusion. ; this is correct option

OPTION E is correct

(A) agreeing with him but adding counterarguments from opponents of that view. --> She did not present counterarguments, rather just presented additional facts. INCORRECT

(B) conceding that his evidence is valid but drawing attention to other evidence that refutes his argument. --> She just drew his attention to other evidence but did not refute his argument. INCORRECT

(C) initially agreeing with him but then changing her mind by drawing upon comparisons. --> no comparison was presented. INCORRECT

(D) ignoring it and attacking the implications of his facts to support her counterargument. --> She did not ignore David's argument, rather she agreed to it. INCORRECT

(E) acknowledging the facts he uses to support his argument but offering additional information to consider without herself making a conclusion. --> CORRECT

Lynn responds to David’s argument by

(A) agreeing with him but adding counterarguments from opponents of that view. - Nothing is mentioned about opponents.
(B) conceding that his evidence is valid but drawing attention to other evidence that refutes his argument. - Nothing is mentioned about refuting.
(C) initially agreeing with him but then changing her mind by drawing upon comparisons. - Lynn does not compare
(D) ignoring it and attacking the implications of his facts to support her counterargument. - Lynn does not ignore
(E) acknowledging the facts he uses to support his argument but offering additional information to consider without herself making a conclusion. - Correct

(B) IMO



If we closely look at Lynn's argument, with the very 1st word 'True', she acknowledges David's argument. And the highlighted portions suggest that she provides additional evidence which counters David's argument.

(A) agreeing with him but adding counterarguments from opponents of that view. - Lynn did not directly add any counterargument.
(B) conceding that his evidence is valid but drawing attention to other evidence that refutes his argument. - Perfect as she just draws the attention to her evidence which refutes David's argument. She isn't explicitly refuting David's argument.
(C) initially agreeing with him but then changing her mind by drawing upon comparisons. - She doesn't seem to change her mind
(D) ignoring it and attacking the implications of his facts to support her counterargument. - Easiest to eliminate
(E) acknowledging the facts he uses to support his argument but offering additional information to consider without herself making a conclusion. - Lynn hasn't directly acknowledged the facts used by David.

IMO E

Lynn acknowledge David's word that do not chimpz do not spend time in water like we do, but then Lynn mentioned new facts that we human are the only land species that have those fats. Therefore maybe we aren't arrive from chimpz.

Lynn responds to David’s argument by

(A) agreeing with him but adding counterarguments from opponents of that view. -agree on somepart only not all
(B) conceding that his evidence is valid but drawing attention to other evidence that refutes his argument. -she just belive the fact that 98% dna shared, but didn't said that David evidence is valid
(C) initially agreeing with him but then changing her mind by drawing upon comparisons. -didnt change her mind just add adi info
(D) ignoring it and attacking the implications of his facts to support her counterargument.-she didn't ignore she said 'TRUE, but'
(E) acknowledging the facts he uses to support his argument but offering additional information to consider without herself making a conclusion.

Therefore, E

David: Humans did not evolve from an aquatic ancestor. Chimpanzees, our closest living relatives, share over 98 percent of our DNA, and they don’t swim or spend time in the water unless they have to. They even use leaves to soak up water to drink, rather than cup their hands.

Lynn: True, but we also have a layer of fat under our skin, which would make us unique in the animal kingdom as the only non-aquatic species that has evolved such fat, not to mention that fatty tissue is 90 percent as dense as water, helping us float and thereby conferring a survival advantage that would be useless outside of water.

Lynn responds to David’s argument by

(A) agreeing with him but adding counterarguments from opponents of that view. -> Lynn doesn't counterarguments from opponents. Incorrect.
(B) conceding that his evidence is valid but drawing attention to other evidence that refutes his argument. -> It is better. Let's keep it.
(C) initially agreeing with him but then changing her mind by drawing upon comparisons. -> He doesn't change his mind. Incorrect.
(D) ignoring it and attacking the implications of his facts to support her counterargument. -> He doesn't ignore it, he accepted the facts. Incorrect.
(E) acknowledging the facts he uses to support his argument but offering additional information to consider without herself making a conclusion. -> Lynn made a conclusion. Incorrect.

So, I think B.

David: Humans did not evolve from an aquatic ancestor. Chimpanzees, our closest living relatives, share over 98 percent of our DNA, and they don’t swim or spend time in the water unless they have to. They even use leaves to soak up water to drink, rather than cup their hands.

Lynn: True, but we also have a layer of fat under our skin, which would make us unique in the animal kingdom as the only non-aquatic species that has evolved such fat, not to mention that fatty tissue is 90 percent as dense as water, helping us float and thereby conferring a survival advantage that would be useless outside of water.

Ha! this one seems tricky, but lets get into the answer choices.

Lynn responds to David’s argument by

(A) agreeing with him but adding counterarguments from opponents of that view. She is definitely coming up with a counterargument of sorts but she is not suggesting what others are stating, she herself is stating additional facts.
(B) conceding that his evidence is valid but drawing attention to other evidence that refutes his argument. His conclusion is that humans did not evolve from an aquatic ancestor, Lynn actually states that humans are non-aquatic species. She is definitely not using the evidence to refute the argument as a whole.
(C) initially agreeing with him but then changing her mind by drawing upon comparisons. no she is pretty steady about her response, not changing her mind later on.
(D) ignoring it and attacking the implications of his facts to support her counterargument. Nope this is straight out wrong, she acknowledges first.
(E) acknowledging the facts he uses to support his argument but offering additional information to consider without herself making a conclusion. I like this one, she definitely acknowledges and then adds information without actually making a conclusion about what her intention is.

(A) agreeing with him but adding counterarguments from opponents of that view.
We are not sure if counterarguments are from opponents or are from Lynn herself

(B) conceding that his evidence is valid but drawing attention to other evidence that refutes his argument.
Lynn is not trying to refute the argument provided by David. This is too extreme

(C) initially agreeing with him but then changing her mind by drawing upon comparisons.
changing her mind. Hahaha this must be a joke

(D) ignoring it and attacking the implications of his facts to support her counterargument.
ignoring it: No way. Lynn did acknowledge David's point

(E) acknowledging the facts he uses to support his argument but offering additional information to consider without herself making a conclusion.
This is good. acknowledged the fact and then offered extra information without making any conclusion

David: Humans did not evolve from an aquatic ancestor. Chimpanzees, our closest living relatives, share over 98 percent of our DNA, and they don’t swim or spend time in the water unless they have to. They even use leaves to soak up water to drink, rather than cup their hands.

Lynn: True, but we also have a layer of fat under our skin, which would make us unique in the animal kingdom as the only non-aquatic species that has evolved such fat, not to mention that fatty tissue is 90 percent as dense as water, helping us float and thereby conferring a survival advantage that would be useless outside of water.

Lynn responds to David’s argument by

(A) agreeing with him but adding counterarguments from opponents of that view. : Yes Lynn agreed with David and added counterarguments. Correct

(B) conceding that his evidence is valid but drawing attention to other evidence that refutes his argument. : Yes Lynn conceded that David's evidence is valid but Lynn is not completely refuting David's argument ; She is questioning it and presenting another possibility. Eliminate B

(C) initially agreeing with him but then changing her mind by drawing upon comparisons. : She is not changing her mind her views were the same she agreed with the evidence David provided. Eliminate C

(D) ignoring it and attacking the implications of his facts to support her counterargument. : Lynn is definitely not ignoring David's argument : Eliminate D

(E) acknowledging the facts he uses to support his argument but offering additional information to consider without herself making a conclusion. : Yes this is also partially true but she implies that since "the survival advantage would be useless outside water" there is a chance that humans did evolve from an aquatic ancestor: Eliminate E

So it seems that A is the best IMO

Lynn responds to David’s argument by

(A) agreeing with him but adding counterarguments from opponents of that view He is not arguing on opponentss view.

(B) conceding that his evidence is valid but drawing attention to other evidence that refutes his argument Yeah true, He accepted the evidence and presented other evidence where the conclusion won't hold.

(C) initially agreeing with him but then changing her mind by drawing upon comparisons He never denies the evidence shown by his opponent.
(D) ignoring it and attacking the implications of his facts to support her counterargument. He never denies the evidence shown by his opponent.
(E) acknowledging the facts he uses to support his argument but offering additional information to consider without herself making a conclusion.

It's not just additional information, This information is shattering the conclusion. So E is not a perfect choice.

IMO B
