In this sentence, I was told I should use “quest” in its singular form.
“Explain how William Bradford’s and John Winthrop's texts relate to each other in terms of the legitimacy of the Pilgrims’ and the Puritans’ religious quests and actions”
However, don't we use two apostrophes only when we are talking about two things that belong to two different people? For example, if I say "John's and Brian's cars", I am talking about two cars, one of which John owns and one that Brian owns. If I am talking about just one car that belongs to both of them, I have to say "John and Brian's car". I need to use just one apostrophe and I need the singular "car". I can't say "John's and Brian's car", can I? If I use two apostrophes, I need the plural "cars". Doesn't the same rule apply to my example? If I am talking about just one quest, I mean, if the Pilgrims and the Puritans had the same religious quest, I should use just one apostrophe for both of them, shouldn't I? " in terms of the legitimacy of the Pilgrims and the Puritans’ religious quest". I can't have two apostrophes if I am using the singular "quest", can I?
Please, I need some help
