Brain Scan Volunteers OG16 Q73

Post Fri Sep 18, 2015 1:50 am
73. Researchers studying the brain scans of volunteers who pondered ethical dilemmas have found that the basis for making tough moral judgments is emotion, not logic or analytical reasoning.



(A) the brain scans of volunteers who pondered ethical dilemmas have found that the basis for making tough moral judgments is


(B) the brain scans of volunteers who pondered ethical dilemmas and found the basis to make tough moral decisions to be


(C) the brain scans of volunteers pondering ethical dilemmas and found that the basis for making tough moral decisions is


(D) volunteers’ brain scans while pondering ethical dilemmas have found the basis to make tough moral judgments to be


(E) volunteers’ brain scans while they pondered ethical dilemmas have found that the basis for


I get the OA A but I would like to get a brief note on the meaning part especially understanding the split between the brain scans of volunteers vs volunteers’ brain scans. I have seen many times GMAT hates the usage of Possessives especially for 'humans'. Am I missing any kind of rule here?

Hi GMATGuru ,

Just a quick question here.

Puller possessive is always wrong in gmat? If not then can you please advise when should we use this?

Please advise sir.

Thanks
Plural possessives TEND to be in incorrect answer choices, but they are not ALWAYS wrong.

Examples of plural possessives contained in OAs from GMAC:
the local artisans’ creative energy.
the mollusks' growth

Examples of plural possessives contained in incorrect answer choices from GMAC:
business journals' and general consumer magazines' advertising income
executives' being heavily committed to a course of action

If you see an answer choice with a plural possessive, do not immediately eliminate the answer choice.
Instead:
Check the answer choice for other errors.
Look for an alternate answer choice that avoids the plural possessive and is free of errors.
If you are stuck between an answer choice that contains a plural possessive and one that avoids this usage, choose the answer choice without the plural possessive.
