Boundaries and Punctuation in one look
one question decides it: can each side of the blank stand alone?
What this question actually looks like
- a short passage of roughly 25 to 150 words sits above the question and belongs to that question alone, so there is nothing long to hold in your head
- the passage carries a blank, and the stem is always the same words: which choice completes the text so that it conforms to the conventions of Standard English
- the four options are the same words in the same order, differing only in the punctuation dropped between them
- because only the punctuation moves, the passage's meaning barely matters here. You are reading structure, not argument
- that is why this is one of the fastest question types on the whole section. Time saved here is what pays for the slow evidence questions later
The only test you have to run
- an independent clause has a subject and its own finite verb, and could be printed as a sentence on its own with nothing added
- a dependent clause opens with because, although, when, since, while, which or that, and cannot be printed alone however long it runs
- read the words to the LEFT of the blank, then the words to the RIGHT, and label each side whole or not whole
- length tells you nothing. A fourteen word phrase can still be a fragment, and a three word clause can be complete: she agreed
- that one pair of labels eliminates three of the four options without your ever deciding what the passage is about
Is each side of the blank a complete sentence on its own?
- both sides complete, no joining word offered — Period or semicolon: only one of the two will appear in the options
- both sides complete, a joining word is in the option — Comma, then and, but, so: the comma sits before the joining word, never after
- one side is not a complete sentence — Comma, or no mark at all: a semicolon here is wrong every single time
Openers that make a clause dependent
- Because, since: give a reason, so the clause needs a main clause beside it to lean on
- Although, while: concede something, and can never close a sentence by themselves
- When, after, before: fix a time, and are the ones most often mistaken for complete sentences
- Which, who: attach a description to a noun already named, never start a new sentence in these options
- That, whether: open a clause that works as an object, so it is part of a larger sentence
