Question

a well - known soporific herb, lavender is often used as a gentle treatment for insomnia.
what does soporific mean?
1 delicately fragranced
2 sleep - inducing
3 naturally occuring

Explanation:

The sentence mentions that lavender is used for insomnia. Insomnia is a sleep disorder. So, the herb's property (soporific) should relate to sleep. "Sleep - inducing" directly connects to helping with sleep (to treat insomnia). "Delicately fragranced" is about smell and has no relation to treating insomnia. "Naturally occurring" is about its existence in nature, not its effect on sleep.

Answer:

1. sleep - inducing
