An infinitive is a type of D. Verbal. It is one of the three types, besides gerunds and participles that are the other two types of verbals, whereas appositive is not a type of a verbal.

2. After Mary heard about the hurricane warning in her area, she looked for a safe place.

<h3>What is a cause-and-effect phrase?</h3>
A cause-and-effect phrase is a group of words that show the relationship between something and the resultant effect of that thing. In many of the sentences, we can see that one event often leads to another.
For instance, when a thunderstorm strikes, the resultant effect is that there is a loss of power. Another example is that the lady or girl had to stay inside because the weather was bad. Two events are often interconnected in these cases.
