The Falkirk Wheel is Reading Passage 2 in Cambridge IELTS 11, Test 1, Academic Reading. The passage describes the world's first and only rotating boat lift - the Scottish engineering structure built as part of the Millennium Link project to reconnect the Forth & Clyde Canal with the Union Canal, 35 metres above. The 13 questions test True/False/Not Given (Q14-19) and diagram labelling using one word from the passage (Q20-26).
Passage overview at a glance
Look at the diagram before reading the passage. The seven labels (Q20-26) describe the boat's journey from canal basin through the wheel to the Union Canal. Knowing the sequence helps you locate each answer quickly in the technical paragraphs about how the wheel operates.
What the passage is about
The Falkirk Wheel passage covers the engineering challenge of reconnecting two Scottish canals separated by 35 metres of vertical drop after the original 11-lock connection was dismantled in 1933. It traces the 1994 launch of the Millennium Link project, the design competition that produced the rotating-wheel concept, the construction at Butterley Engineering's Steelworks in Derbyshire, the transport and on-site assembly at Falkirk, and the technical operation of the wheel - the gates, hydraulic clamp, central axle, cog system, gondolas using Archimedes' principle to maintain constant weight, the aqueduct connection above, and the final pair of locks needed to clear the historically important Roman Antonine Wall before reaching the Union Canal.
Complete answer key with explanations
Questions 14-19: True / False / Not Given
Mark TRUE if the statement agrees with the information in the passage, FALSE if it contradicts, and NOT GIVEN if not addressed.
| Q# | Statement | Answer | Where to find it |
|---|---|---|---|
| 14 | The Falkirk Wheel has linked the Forth & Clyde Canal with the Union Canal for the first time in their history. | FALSE | Paragraph 2 explains that the two canals "had been joined near the town of Falkirk by a sequence of 11 locks" historically, which "had been dismantled in 1933, thereby breaking the link". The wheel restored an old connection - it did not create a first-time one. |
| 15 | There was some opposition to the design of the Falkirk Wheel at first. | NOT GIVEN | Paragraph 3 says numerous ideas were submitted and the eventual winner was the rotating boat lift, but the passage does not say whether anyone opposed the chosen design. Opposition is not addressed. |
| 16 | The Falkirk Wheel was initially put together at the location where its components were manufactured. | TRUE | Paragraph 4 states the parts were "all constructed and assembled, like one giant toy building set, at Butterley Engineering's Steelworks in Derbyshire". Constructed and assembled in the same place = manufactured and put together at the same location. |
| 17 | The Falkirk Wheel is the only boat lift in the world which has steel sections bolted together by hand. | NOT GIVEN | Paragraph 4 confirms the bolts were hand-tightened ("each bolt was hand-tightened") but the passage does not claim this is unique to the Falkirk Wheel. Uniqueness in this specific construction technique is not addressed. |
| 18 | The weight of the gondolas varies according to the size of boat being carried. | FALSE | Paragraph 5 explicitly states "these gondolas always weigh the same, whether or not they are carrying boats" - thanks to Archimedes' principle of displacement. Always the same weight contradicts varies with boat size. |
| 19 | The construction of the Falkirk Wheel site took into account the presence of a nearby ancient monument. | TRUE | The final paragraph explains the wheel was constrained "owing to the presence of the historically important Antonine Wall, which was built by the Romans in the second century AD". Historically important Roman wall = ancient monument. Being constrained = taking it into account. |
Questions 20-26: Diagram labelling (ONE WORD ONLY)
The diagram shows how a boat is lifted on the Falkirk Wheel. Each gap is labelled with ONE WORD from the passage. All seven answers come from the operating-sequence paragraphs (paragraphs 6 and the final one).
| Q# | Label context | Answer | Where to find it |
|---|---|---|---|
| 20 | A pair of __________ are lifted in order to shut out water from canal basin. | gates | Paragraph 6 describes how "two hydraulic steel gates are raised, so as to seal the gondola off from the water in the canal basin". Raised = lifted; seal off = shut out. |
| 21 | A __________ is taken out, enabling Wheel to rotate. | clamp | Paragraph 6 explains "a hydraulic clamp, which prevents the arms of the Wheel moving while the gondola is docked, is removed". Removed = taken out; allowing the wheel to turn = enabling to rotate. |
| 22 | Hydraulic motors drive __________. | axle | Paragraph 6 says "an array of ten hydraulic motors then begins to rotate the central axle". Rotate = drive (in mechanical sense). |
| 23 | A range of different-sized __________ ensures boat keeps upright. | cogs | Paragraph 6 describes the gearing system: "two eight-metre-wide cogs orbit a fixed inner cog of the same width, connected by two smaller cogs travelling in the opposite direction". Multiple sizes of cogs keep the gondolas level - i.e. boats upright. |
| 24 | Boat reaches top Wheel, then moves directly onto __________. | aqueduct | Paragraph 6 ends with "when the gondola reaches the top, the boat passes straight onto the aqueduct situated 24 metres above the canal basin". Passes straight onto = moves directly onto. |
| 25 | Boat travels through tunnel beneath Roman __________. | wall | The final paragraph says the wheel could not cover the full 35-metre drop because of "the historically important Antonine Wall, which was built by the Romans". Boats then "travel under this wall via a tunnel". Under = beneath. |
| 26 | __________ raise boat 11m to level of Union Canal. | locks | The final paragraph opens with "the remaining 11 metres of lift needed to reach the Union Canal is achieved by means of a pair of locks". 11 metres of lift = raise 11m. |
Question type strategy for this passage
True / False / Not Given
Q14-19 do not follow strict passage order - Q14 is in paragraph 2, Q19 in the final paragraph. Use the keywords (Forth & Clyde, opposition, Butterley, hand bolted, gondolas weight, Roman wall) to scan rather than re-reading the whole passage.
Diagram labelling
Q20-26 are in passage order and concentrated in paragraph 6 (the operating-sequence) plus the final paragraph. Read paragraph 6 carefully once before attempting them. ONE WORD ONLY means no plurals if the passage uses singular and no articles.
Watch for missing claims
Q15 (opposition) and Q17 (only boat lift bolted by hand) are both NOT GIVEN. The trap is that both topics ARE discussed in the passage - design history, hand-tightened bolts - but the specific claims in the questions (opposition, uniqueness) are never made. Discussed is not the same as claimed.
Time management
About 18 minutes for this Passage 2 of 3. The diagram labels are quick once you have read paragraph 6. Spend more time on the T/F/NG questions - particularly Q15 and Q17 where the NOT GIVEN traps catch most candidates.
Vocabulary worth learning from this passage
- Gondola, in this context, a large water-filled container attached to the wheel that carries the boats
- Aqueduct, a bridge-like structure carrying water across a valley or low ground
- Hydraulic, operated by liquid pressure
- Clamp, a device that holds something firmly in place
- Cog, a toothed wheel that engages with another to transmit motion
- Axle, a rod or shaft on which a wheel rotates
- Dismantle, to take apart, the opposite of assemble
- Archimedes' principle, the law that a floating object displaces its own weight in water

Frequently asked questions
Which Cambridge IELTS book contains The Falkirk Wheel?
The Falkirk Wheel is Reading Passage 2 in Cambridge IELTS 11, Test 1, Academic Reading. The first passage in that test is Crop-growing Skyscrapers and the third is Reducing the Effects of Climate Change.
How difficult is the Falkirk Wheel passage?
Medium difficulty. The technical vocabulary (axle, cog, gondola, hydraulic) sounds intimidating but the passage explains everything in context. The harder part is the True/False/Not Given questions - two of the six are NOT GIVEN traps where the topic IS discussed but the specific claim never made.
Why is Q17 NOT GIVEN and not TRUE?
Q17 says the Falkirk Wheel is the only boat lift in the world bolted together by hand. The passage confirms hand-tightening of the bolts but never compares the wheel to any other boat lift on this specific point. Without a comparison statement, the uniqueness claim is unsupported. NOT GIVEN is correct.
How should I approach diagram-labelling questions?
Read the diagram first to see the layout and labels. Identify the part of the passage describing the same sequence - here, paragraph 6 (operating cycle) and the final paragraph (post-wheel journey). Then work through gaps in order. The instruction is ONE WORD ONLY, so check each answer is exactly one word.
Where can I find the original passage text?
The full passage and official answer key are in Cambridge IELTS 11 (Cambridge University Press), available from major bookstores and online retailers.
