"instruction": "This is a standalone EEG/BCI knowledge multiple-choice question. No EEG data file is needed. Please answer by selecting exactly one option: A, B, C, or D.\n\nQuestion: Why is the posterior dominant rhythm usually assessed during relaxed wakefulness with eyes closed?\nA. Alpha is necessarily stronger with eyes open.\nB. The posterior dominant rhythm exists only in N3 sleep.\nC. The posterior alpha rhythm is easier to observe when the eyes are closed and the person is relaxed.\nD. Posterior dominant rhythm is another name for eye-blink artifact."
