Answer 1

Answer:

The second sentence uses the definition of the word.

Explanation :

In the second sentence the subject takes a medication that makes him/her "soporific", meaning it promprs him/her to sleep. Hence, the person has to avoid driving since it can be dangerous.  In the rest of the example there is no logical connection between the noun affected by "soporific" and the predicate: in all the other cases the effects stated are those of excitement, accelaration, and enhancement.
