Add an exclamation mark after “What an achievement”

Why make these changes? Well, for the first change, we would add a question mark because Davina is being asked how things are with her. By not adding a question mark, this sentence conflicts with the next one. In the second change, we would change the w to a capital W because the last sentence ended with a period, meaning the W is the first letter of the next transitioning sentence and would therefore require capitalization. In the third change, we would add an exclamation mark because Davina is being congratulated on her new job position. Although it would make sense to add a period, it would also make the sentence appear a bit shady or envious. In the fourth change, a question mark is needed because Davina is being asked a question for confirmation of where she and her friend had planned to meet.

The sentence in which the underlined infinitive phrase functions as a subject is the last one - to quickly move large groups of people is the purpose of public transportation. <em>To quickly move </em>is the infinitive phrase, and it is a subject.
