Answer:
Hello. You didn't put any words in bold. However, the only infinitive word in all sentences shown in the question above is "To remain"
Explanation:
In any case, infinitive words are verbs that are accompanied by the word "to" that is placed before the verb and never after.
In other words, when a verb is preceded by the word "to" it is an infinitive verb and represents a nominal form of the verb, which can be classified as a personal or impersonal infinitive verb, depending on how it fits into the sentence.
