2.4 Sentence Completion

2.4 Sentence Completion

What the Item Is Testing

A sentence-completion item measures two things at once: vocabulary (do you know the words?) and logic (do you see how the clauses connect?). The PAF verbal battery leans on the logic side, so the signal words matter more than obscure vocabulary. Most wrong answers are grammatically fine but logically wrong because they ignore the signal.

The Method

1. Read the whole sentence. Do not look at the options yet. If there are two blanks, read to the end both times.
2. Identify the signal word. Although, despite, however, yet signal contrast. Therefore, thus, hence, so signal cause-effect continuation. Moreover, additionally, furthermore signal addition. Because, since signal cause.
3. Predict each blank's direction. For a contrast stem, the second blank should oppose the first idea. For a cause-effect stem, the second blank should follow from the first.
4. Predict a word. Whisper a plain word for each blank before scanning options.
5. Scan and match. Pick the option closest to your prediction. If two options are close, your prediction was too loose; tighten it with the sentence's detail.

Worked Example 1 (Single Blank)

Stem: The reconnaissance sortie was ______ because thick cloud cover hid the target area.

Options: (A) SUCCESSFUL (B) ABORTED (C) PLANNED (D) REWARDED.

Signal: because — cause-effect. The cause is thick cloud hiding the target, which prevents success. Predict: "called off, unsuccessful." Scan: ABORTED matches. SUCCESSFUL contradicts the cause, PLANNED is neutral and ignores the cause, REWARDED is an effect with no supporting cause. Answer: B.

Worked Example 2 (Double Blank)

Stem: Although the instructor was ______ when correcting errors, trainees generally found the debriefs ______ because the feedback improved their performance.

Options: (A) HARSH ... BENEFICIAL (B) GENTLE ... WASTEFUL (C) SILENT ... CONFUSING (D) FRIENDLY ... OPTIONAL.

Signal: although signals contrast; because signals cause-effect for the second blank. The first blank should be a tough or stern word (the contrast set-up), and the second blank should be a positive word (the payoff). Predict: "stern ... helpful." Scan: HARSH ... BENEFICIAL matches both. GENTLE ... WASTEFUL breaks the contrast because gentle does not need an although, SILENT ... CONFUSING makes the second clause negative which fights the because, and FRIENDLY ... OPTIONAL loses the contrast on the first blank. Answer: A.

Signal-Word Reference

Keep this list ready during practice. Each word tells you the direction the blank must take.

• Contrast: although, though, even though, despite, in spite of, however, yet, still, nevertheless, nonetheless.
• Cause-Effect: because, since, as, therefore, thus, hence, so, consequently, accordingly.
• Addition: moreover, furthermore, additionally, besides, also, likewise, similarly.
• Restatement: in other words, that is, namely, i.e., e.g.

The Double-Blank Strategy

On a two-blank item, one blank usually carries the stronger clue. Test that blank first. In Example 2, the second blank has the because clause as its clue, which is more specific than the although clue on the first blank. Testing the second blank first eliminates (B), (C), and (D) before you even check the first blank, saving time.

Grammatical and Tone Cues

If an option produces a sentence that sounds awkward or shifts tone mid-way, reject it even if the meaning is close. PAF stems are written in a clean, formal register. An option that slips into slang or odd phrasing is almost always a distractor.

Common Traps

• The synonym trap: two options are near-synonyms for the predicted word; only one fits the second blank or the signal. Always check both blanks.
• The reversal trap: one option reverses the signal (e.g. picks a positive word where the signal demanded negative). Mark the signal before scanning.
• The grammar trap: an option with the right meaning but the wrong part of speech. Check that the blank's slot expects a noun, verb, or adjective as the sentence requires.

Speed Notes

Predict before you scan. Students who test each option against the stem cold spend 40-50 seconds per item; students who predict spend 15-20. Over a 100-item battery, that gap is the difference between finishing and leaving the last 15 questions blank.

Worked Example 3 (Cause-Effect with Aviation Setting)

Stem: The flight line was closed for sweeping; ______, the cadets were reassigned to classroom briefing until the surface was clear.

Options: (A) THEREFORE (B) HOWEVER (C) MEANWHILE (D) ALTHOUGH.

Signal: the second clause describes a consequence of the closure, so the blank must mark cause-effect continuation. Predict: "so, as a result." Scan: THEREFORE matches. HOWEVER would signal contrast, but the second clause follows logically from the first. MEANWHILE marks simultaneous action, not consequence. ALTHOUGH introduces a concession, which the sentence does not support. Answer: A.

Tone-Consistency Trap

PAF sentence-completion stems sit in a clean, formal register. If an option is correct in meaning but slips into colloquial tone — pretty good, kinda, a lot of — reject it in favour of the formal equivalent. Item writers rarely mix registers within a stem, so a single informal option among three formal ones is almost always a distractor placed to catch students who test only meaning and ignore tone.

Final Speed Rule

If a stem has two blanks and you cannot predict either after one read, mark the signal word, eliminate any option whose first blank contradicts the signal, and guess from the remainder. Spending 60 seconds on one item risks the last ten questions of the battery.
