Dangling Modifiers
A dangling modifier is an opening phrase with no logical subject in the sentence it's attached to, so it ends up describing the wrong noun, or no noun at all. You fix it by making the subject of the main clause the thing that phrase actually describes.
Every sentence that opens with a phrase like 'Running down the street,' or 'After studying all night,' makes a promise: the subject right after the comma is the thing doing that action. 'Running down the street, the mailbox appeared closer' breaks that promise. Mailboxes don't run. The phrase needs a runner in the subject slot, and the sentence never supplies one. That's the test's version of a dangling modifier: a hook swinging for a noun that isn't there.
A misplaced modifier is a cousin, not a twin. There, the right noun does exist in the sentence, just too far from the phrase, so the phrase grabs a nearby word by accident. A dangler is worse: the noun it needs is simply missing. Fixing a dangler means rewriting the main clause so its subject is the one performing the opening action. 'After studying all night, the exam felt easy' becomes 'After studying all night, Maria found the exam easy' — Maria studied, so Maria leads the clause. 'Having been left in the sun, we found the chocolate melted' can go two ways: keep 'we' as the finder and name the chocolate as the thing left in the sun ('Having been left in the sun, the chocolate had melted when we found it'), or rebuild the opener around the chocolate directly.
This sits next to possessive and prepositional openers because the same rule governs them. A possessive like 'my' in 'Walking home, my hat blew off' doesn't rescue the sentence — 'hat' is the subject, and hats don't walk; you need 'I' there. Prepositional openers such as 'At the age of nine, after six years of lessons,' make the identical claim on the subject, so the fix is identical: put the performer first.
