Explanation:

Let’s break this down step by step:

- C: This segment opens things up. It introduces "mental health stigmas, antiquated beliefs that psychotherapies are hokum," which is the "what."

- E: Follows naturally: "and social and financial barriers to treatment combine" — it extends the idea about what’s making things tough.

- A: Now, the sentence needs to show the result: "to keep millions of Americans young and old from getting much-needed…"

- D: This piece plugs into A perfectly: "help with depression, a common and increasingly pervasive…"

- B: Lastly, we’re told what, exactly, depression is: "mental health disorder that can affect anyone at any age."

So, the sequence is CEADB.

Option 1: CEADB is correct.

Here’s what the options do wrong:

- Option 2 and 3 start talking about the disorder before setting up the barriers—doesn’t read right.

- Option 4 and 5 make confusing jumps; they don’t set up the “what’s the problem, here’s the effect” flow.
