A.I. Explanation:

Option 1: "Disrupted sleep is the most common experience of migraine."

Explanation: The text states that an incapacitating headache is one of the most common experiences of migraine, not disrupted sleep. Therefore, this option misrepresents the information.

Option 2: "Migraine may include a variety of symptoms."

Explanation: The text explicitly mentions that a migraine can include symptoms such as a throbbing headache, sensitivity to light, and disrupted sleep, indicating a variety of symptoms. This aligns perfectly with the main idea of the text.

Option 3: "Headache is always involved in migraine."

Explanation: The text clarifies that some migraines don’t even involve a headache, contradicting this option. Thus, it inaccurately represents the speaker's message.

Option 4: "Light sensitivity is not the symptom of migraine."

Explanation: This option is incorrect because the text lists sensitivity to light as one of the symptoms of migraine, directly contradicting the statement.
