Answer: All sentences have an infinitive that takes the place of a noun.
Step-by-step explanation:
- An infinitive is the basic form of a verb. It consists of 'to' + the verb form.
- For example: to read, to write, to learn, etc.
- Infinitive is a verbal, which means that it is used as some other part of the speech. In this case, infinitive forms are used as nouns.
- Apart from the infinitives, gerunds (-ing forms) and participles (-ing and -en forms) are also considered as verbals. However, neither gerunds nor participles appear in the sentences given in this example.
