Answer 1

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

The sentence is quite straight forward - researchers studied brain scans of volunteers who pondered ethical dilemmas. The researchers found that basis for the solutions of these dilemmas was emotion and not logic or reasoning. There is no subject-verb error, no modifier error. Thus, option A is the answer. Option B cannot be the answer as it does not provide a verb for the subject 'researchers'. Also, 'volunteers pondered and found' implies that the volunteers themselves came to some conclusions after some thinking. C also has a subject without a verb. Options D and E does not make any sense- both seem to state that the researchers pondered 'ethical dilemmas' while studying the brain scans of volunteers.
