a) Use bright artificial light in the evening
b) Administer sleep-inducing medication
c) Encourage participants to sleep during the day
d) Expose participants to natural daylight in the morning

Answer 1

According to the 'How to sleep' TED Talk, the best way for Dr. Kim to conduct her study and help participants' body clocks go back to the natural rhythm of their ancestors would be to expose participants to natural daylight in the morning.

Step-by-step explanation:

The BEST way for Dr. Kim to conduct her study and help participants' body clocks go back to the natural rhythm of their ancestors, according to the 'How to sleep' TED Talk, would be to expose participants to natural daylight in the morning (d). This is because the biological clock is driven by light, and exposure to natural daylight in the morning can help realign and regulate circadian rhythms. Bright artificial light in the evening (a) or administering sleep-inducing medication (b) may disrupt the natural rhythm further, and encouraging participants to sleep during the day (c) would not align with the natural sleep-wake cycle.
