Economic analysts, noting the sharp increase in ADHD-related disability claims over the past decade, have posited an epidemic of ADHD among younger generations. These analysts, though, ignore advances in psychoanalytical classifications. ADHD is now listed as an official psychiatric disorder in the DSM-5, whereas those with ADHD were simply treated as undisciplined and irresponsible in the past. Therefore, a greater number of serious cases are recommended now for disability, because Human Resources workers are more likely to identify these behavior patterns as ADHD.

Which of the following, if true, provides the most support for the argument?

A:Most economic analysts have no more than a rudimentary knowledge of psychiatric classifications.

B:Even though ADHD is a psychiatric disorder, coaching in skills related to responsibility and self-discipline help many such individuals lead more productive lives.

C:Human Resource employees now receive basic training in the psychiatric disorders that most commonly lead to disability claims.

D:In some cultures in the past, the lack of responsibility was viewed as one of the most serious moral failings.

E:According to studies, psychiatrists are diagnosing children with ADHD at increasingly early ages.
