6.2 Part 6: Gapped Text — Text Structure, Cohesion, Coherence & Reference Markers

6.2 Part 6: Gapped Text — Cohesion, Coherence & Reference Markers

Quick Answer: In Part 6 (Gapped Text), candidates read a text of roughly 500 to 600 words from which 6 sentences have been removed (numbered 37 to 42). Following the text is a jumbled bank of 7 sentences (A to G), meaning one sentence is an extra distractor that does not fit anywhere. Each correctly placed sentence earns 2 marks, providing 12 raw marks toward the Reading subscale. Part 6 does not test general topic comprehension; it evaluates discourse cohesion and coherence—specifically how ideas, pronouns, time markers, and grammatical structures link across sentence boundaries.

Part 6 Format & Exam Architecture

Part 6 is universally regarded as the most intellectually demanding reading task on the Cambridge B2 First paper. While a student can guess on a four-option multiple-choice item in Part 5 without impacting other items, placing an incorrect sentence in Part 6 initiates a cascade failure: assigning sentence C to gap 38 inevitably deprives gap 41 of its correct match.

The Cohesion and Coherence Linguistic Toolkit

To solve Part 6 reliably, you must stop treating the text as a sequence of isolated sentences. Texts are woven together using explicit linguistic devices. When a sentence is removed, it leaves behind "torn threads" both before and after the gap. Your job is to locate the sentence in the bank that knits those threads together.

1. Grammatical Reference Markers

Reference words refer to people, entities, or entire clauses mentioned elsewhere in the discourse:

• Anaphoric Reference (Pointing Backward): Words that point back to an antecedent in the preceding text. If a sentence in the bank starts with "They had spent months preparing for this moment," the preceding text must mention a plural group of people (or animals). If the preceding sentence discusses only "Dr. Aris Thorne, a lone botanist," this sentence is grammatically impossible.
• Cataphoric Reference (Pointing Forward): Words that point forward to an entity explained in the following sentence. For example: "The explanation was simple. The underground chamber had collapsed during the storm."
• Demonstratives as Discourse Summarizers: Demonstrative pronouns (this, that, these, those, such) frequently encapsulate an entire complex situation described in the preceding sentence:
  • Pre-gap text: The team suffered severe frostbite, ran out of clean drinking water, and lost their satellite radio.
  • Gapped sentence: These harrowing conditions forced the expedition leader to call for an immediate evacuation.
  • Demonstrative clue: Notice how these harrowing conditions summarizes the three distinct hardships detailed prior to the gap.

2. Discourse Connectors & Logical Transitions

Discourse markers signal the logical direction of an argument. When you encounter a connector in a candidate sentence, check whether the surrounding text satisfies its logical prerequisite:

• Contrast & Concession (however, nevertheless, on the contrary, conversely, despite this, yet): The preceding sentence must present a contrasting thesis, positive development, or expectation that the gapped sentence disrupts.
• Addition & Amplification (furthermore, in addition, moreover, not only that, equally): The gapped sentence must provide an extra piece of supporting evidence aligned in tone and direction with the previous point.
• Cause, Effect & Result (consequently, therefore, as a result, hence, thus): The preceding sentence must supply the direct cause or trigger for the event described in the gapped sentence.
• Temporal & Sequential Flow (subsequently, meanwhile, prior to this, eventually, in the meantime): Chronological storytelling requires rigid temporal logic. A sentence mentioning subsequently cannot precede the inaugural event.

3. Lexical Cohesion & Semantic Chains

Authentic writers avoid monotonous word repetition by building semantic webs using related vocabulary:

• Hypernyms & Hyponyms (General to Specific): A general umbrella category (hypernym) links to specific instances (hyponyms).
  • Example: If the pre-gap text mentions "a varied assortment of delicate surgical instruments," the matching sentence might refer to "scalpels, forceps, and micro-clamps."
• Synonymy & Conceptual Paraphrase: If the lead-in sentence discusses "a catastrophic financial collapse," the inserted sentence might elaborate on "the severe economic ruin that engulfed the region."
• Collocational Semantic Fields: Words that naturally co-occur in specialized domains (e.g., in a marine biology text: currents, salinity, reef ecosystem, pelagic species, bioluminescence).

4. Grammatical Agreement & Tense Consistency

A sudden, unjustified tense shift across a gap boundary indicates an erroneous insertion. If the narrative before and after the gap is grounded in the past simple and past perfect (had traveled, arrived, discovered), a sentence written in the present simple discussing current lifestyle trends is almost certainly an alien distractor.

Text Structure: The Macro Layer Above Cohesion

Cohesion devices tell you how two adjacent sentences hook together. They are necessary but not sufficient, because Cambridge names three focuses for Part 6 — "cohesion, coherence, text structure" — and the third one operates at the level of the whole passage. The handbook is explicit that "rather than concentrating on individual sentences, candidates need to be able to follow the development of ideas, opinions and events through the text as a whole".

This matters mechanically. Two candidate sentences can both be cohesively plausible at a gap — both begin with a matching pronoun, both share vocabulary with the preceding line — and only one can be right. The tiebreaker is almost always macro-structure: which sentence belongs at this stage of the text's argument or narrative?

The Four Structural Patterns You Will Meet

The Structural Sweep: Read the Text Before the Options

Before you look at sentences A to G, read the gapped text straight through and write a three- or four-word label beside each paragraph — the discovery, early scepticism, how she tested it, what changed. This takes about ninety seconds and converts an unordered pile of seven sentences into a set of candidates with known addresses.

Then, at each gap, ask two questions in this order:

1. Structural: what stage of the argument or story is this? A cause, an example, a consequence, a reversal, a summing-up?
2. Cohesive: which of the surviving sentences hooks to the words immediately before and after?

Doing the structural question first is what prevents the classic Part 6 failure mode — choosing a sentence that reads beautifully across the join but puts the outcome of the story two paragraphs before it happened.

Worked Structural Elimination

Text before gap 39: "For three seasons the excavation produced nothing but broken pottery. Morale in the team sank." Text after gap 39: "Within a fortnight the trench had yielded four intact bronze figurines."

Two options survive a purely cohesive check, because both refer back plausibly:

• E) "The finds were eventually displayed in the national museum, where they remain the collection's centrepiece." — cohesively fine (the finds picks up an earlier idea), but structurally impossible: this is an aftermath sentence, and the text after the gap has not yet reached the discovery.
• C) "Then a change of approach — digging a narrow trial trench on the slope above — altered everything." — Correct. It occupies exactly the structural slot the passage needs: the turning point between the failure described before the gap and the success described after it.

The habit to build: when two options both "sound right", stop comparing their wording and ask which one the story needs next. In Part 6, structure breaks ties that cohesion cannot.

The Trap of the Lone Distractor Sentence (Sentence 7)

Cambridge item writers do not select the extra distractor sentence from an encyclopedia on a random subject. The distractor sentence is written on the exact same subject as the main text. It will contain identical keywords (e.g., mentioning the protagonist's name or the expedition destination).

However, the distractor possesses a fatal flaw. When tested against every gap, it will fail at least one of the following criteria:

• Dangling Reference: It begins with "This decision proved controversial," but none of the available gaps are preceded by a decision.
• Syntactic Rupture: It fits the lead-in sentence reasonably well, but produces complete nonsense when read into the sentence that follows the gap.
• Tense Incompatibility: It shifts into an incompatible grammatical aspect without temporal transition.

The 5-Step Bidirectional Gap Analysis Protocol

To master Part 6, you must enforce a bidirectional rule: never evaluate a sentence based solely on how well it links to the sentence before the gap. You must examine at least two sentences before AND two sentences after the gap.
