In a recently published article, a psychiatrist claimed that negative thinking has been the source of laziness, unsocial behavior, and disease in a large number of his patients.

This answer choice is grammatically incorrect. In Reported Speech, when the reporting verb is in the Past tense (claimed), the following conjugated verbs should also be in the Past. However, has been is in Present Perfect.

What helps us identify this question as a Reported Speech question as well as identify the mistake is the following Stop Sign:

Reported Speech with a reporting verb in Past tense

This answer choice is grammatically incorrect and repeats the original Reported Speech error. In Reported Speech, when the reporting verb is in the Past tense (claimed), the following conjugated verbs should also be in the Past. However, is is in the Present.

What helps us identify this question as a Reported Speech question as well as identify the mistake is the following Stop Sign:

Reported Speech with a reporting verb in Past tense

Although this answer choice corrects the original Reported Speech error by using the Past tense (was), it creates a Parallelism error. The first two items in the list of the sentence are nouns (laziness, disease), but the last item is a verb (behaving). 

In a list of 3 or more items, all the items should be the same part of speech (all nouns, all verbs, or all adjectives).

What helps us identify this question as a Parallelism question as well as identify the mistake is the following Stop Sign:

A list of 3 items or more, separated by commas and and/or before the last item.
