I feel slightly amused by the difficulty level assigned to this question. A 'low' / 5% difficulty level assigned to a question. Even the official guide has given a 'hard' tag to this question.

Hi Sparta_750,

Hi Experts,

Can you explain which is the correct interpretation for the OA?

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.

1. The volunteers thought about ethical dilemmas, then they went for a brain scan. These scans were studied by researchers.
2. The volunteers were thinking about ethical dilemmas while having their brains scanned. These scans were studied by researchers.

To me, it makes more sense to think that the scans happened while the volunteers were pondering instead of pondered. I can't seem to derive this meaning from OA.

PS: I got this question correct using the grammar rules and such. Just want to understand what this sentence is saying.

NunuBot Yes, meaning #2 is correct. That's how these kinds of scans work in real life, but we'd also need more clarification if #1 were intended. When would they have pondered these dilemmas? Have other people never pondered any ethical dilemmas? (Who are these thoughtless people?) At the very least, we'd want past perfect (had pondered) to make that meaning clear.

This leads us to the tense in the OA. Even though the main action is in the present perfect (Researchers . . . have found), it's fine to have the modifier "who pondered" occur in the past. These people pondered something while in the brain scan, and researchers have now found something as a result. We certainly could say "who were pondering." That might even be clearer. But the way the D uses "while pondering," it appears to modify the researchers' action, and C still has the potential for this confusion, so we have no valid option with "pondering" in it.

Thanks for the confirmation!

During my first pass through, I eliminated all the choices with "pondered" because I thought it changed the meaning of sentence. But I found the options with "pondering" to be ambiguous as well, and I was torn between choosing the least ambiguous option...

Just wanted to confirm the OA is indeed ambiguous and i was able to identify the ambiguity. (part of the learning process!)

No, I wouldn't say that the OA is ambiguous. The answers with "pondering" were (hence the problem), and we'd need more clarity if your meaning #1 were intended. But as it stands, I'd say the meaning of the OA is clear and unambiguous. It can't fairly be read the other way.

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.

the right idiomatic structure for 'basis' is: ".... basis for (doing something).."

Since (B) and (D) do not have this idiomatic structure, we can eliminate (B) and (D).

(A) the brain scans of volunteers who pondered ethical dilemmas have found that the basis for making tough moral judgments is - (A) has no error and conveys the meaning perfectly. Hence, (A) is the right answer choice.


(C) the brain scans of volunteers pondering ethical dilemmas and found that the basis for making tough moral decisions is - (C) introduces the following structure to the sentence. The researches studying...... and found that.... - This structure has a parallelism error. Hence, we can eliminate (C).

(E) volunteers’ brain scans while they pondered ethical dilemmas have found that the basis for making tough moral judgments is - the demonstrative pronoun 'they' does not have a clear antecedent (it could possibly refer to scans, or to researchers). Hence, we can eliminate (E).

If you find this explanation helpful, please do give it a kudos :thumbsup: :)
