Option 1 -> Both authors explicitly dismiss magical thinking and mystical approaches to manifestation.
Option 2 -> Both Doty and Brennan ground manifestation in neuroscience (brain networks, reticular activation system) and emphasize behavior change through intentional thinking and purposeful action.
Option 3 -> Only Doty mentions a six-week plan; this is not a shared perspective with Brennan.
Option 4 -> Both authors emphasize internal processes (intention, focus, brain function) rather than external circumstances.
Hence, Option 2 -> The passage clearly states both authors take a scientific approach, with Doty emphasizing "a scientific approach to cultivating resilience and focus" and Brennan "drawing from neuroscience and psychology." The conclusion reinforces this shared view: achieving ambitions depends on "intention, focus, and actionable change - a 'real magic' rooted in our own brains and behaviours" -> correct
