Explanation:

Calculate the frequency of the EEG waves

$$ \text{Number of cycles in } 1.0\text{ second} \approx 10\text{ to } 11\text{ cycles} $$

$$ \text{Frequency} \approx 10\text{ Hz} - 11\text{ Hz} $$

Identify the type of brain wave

$$ 8\text{ Hz} - 12\text{ Hz} \implies \text{Alpha waves} $$

$$ \text{Alpha waves} \implies \text{Relaxed, awake state with eyes closed (e.g., meditating, light relaxation)} $$

Match with the correct activity

$$ \text{Performing yoga in a garden} \implies \text{Relaxed, meditative state (Alpha waves)} $$

Answer:

• A. doing some light reading on a Saturday afternoon
• B. napping at a hotel resort in the early evening
• C. performing yoga in the middle of a garden (Correct answer)
• D. preparing a presentation for an important executive
