bad things

Explanation:

We have been asked to revise the sentence because the use of words that are too generic makes it weak, lacking clarity. In the sentence, "Why would a private detective neglect his duties when bad things are happening?" the words that lack precision and, therefore, clarity are "bad things". By reading the sentence, we do not receive information on what these bad things are. They can refer to anything, from people who are cheating on their spouses to armed conflicts in another country. That's why they should be replaced with something more precise. For example:

- Why would a private detective neglect his duties when murders are happening?

or

- Why would a private detective neglect his duties when terrorist attacks are happening?
