Guide to Part 5: Incomplete Sentences

The Format

This part gives you thirty sentences, each with one blank, and four answer choices per question. You pick the word or phrase that correctly and logically completes the sentence.

This is where the Reading section begins. There's no audio and no time pressure on individual questions. You just have the overall 75-minute clock that's shared across Parts 5, 6, and 7, so you control the pace.

What You're Being Tested On

  • Grammar accuracy, including things like verb tense, subject-verb agreement, pronoun usage, conjunctions, and prepositions
  • Word form recognition, meaning you need to know that "decide," "decision," "decisive," and "decisively" each fill a different grammatical slot
  • Vocabulary in context, because sometimes all four choices are grammatically valid and only the meaning separates them
  • Your awareness of sentence structure and how clauses, phrases, and connectors fit together

Question Categories

Word form. All four choices share the same root word but come in different forms: noun, verb, adjective, adverb. You need to figure out which part of speech the sentence is asking for.

Verb tense and form. The choices differ by tense or form, like "manage," "manages," "managed," and "managing." There will be context clues in the sentence that tell you which one fits.

Prepositions. You'll see four different prepositions like in, on, at, and by. Some of these are logical, but many of them are fixed expressions that you either know or you don't.

Vocabulary. All four choices are grammatically correct in the blank, but only one of them actually makes sense given what the sentence means. These require you to understand the full sentence, not just the grammar.

Conjunctions and connectors. Words like although, because, however, and despite. These questions test whether you understand the logical relationship between the two parts of the sentence.

Pronouns. The choices test different pronoun forms: subject, object, possessive, or reflexive. The sentence structure tells you which form belongs in the blank.

How the Test Tricks You

Same root, wrong form. This is the most frequent trap you'll encounter. Take a sentence like "The manager made a ___ decision." You need an adjective here, not an adverb or a noun. All four choices look similar, but only one makes sense grammatically.

Grammatically fine, contextually wrong. Sometimes more than one choice is grammatically valid in the blank, but only one of them makes logical sense when you read the whole sentence. You have to look at the full picture, not just the words immediately around the blank.

Look-alike words. Words like "affect" vs. "effect" or "economic" vs. "economical" look almost identical but mean different things. They show up as wrong answers on a regular basis.

Fixed preposition pairings. Phrases like "responsible for," "interested in," and "depend on" don't always follow a logical pattern. You can't figure them out from context alone. They just need to be memorized.

How to Approach Each Question

  1. Start by identifying what part of speech is needed. Look at where the blank sits in the sentence. Is it right before a noun? Then you probably need an adjective. Right after a subject? Probably a verb. This one step alone can eliminate one or two choices before you even think about meaning.
  2. Read the full sentence. Some questions can only be answered by understanding the overall meaning, not just the grammar surrounding the blank. Don't skip this step, even when the answer seems obvious from grammar alone.
  3. Watch for signal words. Words like "although" and "despite," or time markers like "yesterday" and "by next month," often point you toward the correct tense or connector.
  4. Keep moving. Try to spend around 20 to 30 seconds per question. If you spend too long here, it steals time from Parts 6 and 7, which are harder and more time-consuming.
  5. When you're stuck, eliminate first. Remove any answer that's clearly the wrong part of speech, then work with whatever's left.
