Premise: 1. Building Inspector was accused of ignoring structural issues
2. Building records have been lost & the building has been demolished
3. Current, inspections are flawless
Conclusion: So, the charges should be dropped.
We have to look for an option wherein somebody is accused of wrongdoing but proof of wrongdoing doesn't exist today, and his work has improved since then. The conclusion says that the charges against accuse should be dropped.
(A) A computer scientist was accused of spreading a computer virus to several large computers, but the charge should be dismissed since the hard drives of those computers have been erased and no record of his malfeasance exists. Also, since then, his work has been untainted by any such actions.
This matches with the reasoning presented in the argument. (B) A teacher was accused of allowing several students to pass a course when they actually failed. This accusation should be discussed at length because even though those students went on to be successful in later grades, the teacher may have passed other undeserving students.
Here accusation is not dropped. (C) Politician A was accused of stealing parts of a speech given by Politician B. This charge is without foundation and should be disregarded because Politician A was not even born when Politician B gave that speech and there exists no recording of the original speech.
Though recordings are not there but people may have heard the speech and drafted Politician A's speech accordingly. (D) A restaurateur is accused of using ingredients past their expiration dates. The accusation seems justified even though there is no evidence of it, because several cases of food poisoning can be linked back to the restaurateur’s place of business.
Here accusation is being justified not dropped. (E) A financial manager is accused of stealing funds from his clients. The charges should be ignored because even though the records show there has been some malfeasance, the identity of the accuser has not been disclosed.
Here the proof of wrongdoing still exists. Reject it. IMO OA should be A.
