In the context of tourism & heritage, which word best completes the following sentence: 'Guides who improvise the story of a building __________ the trust of visitors who later read an account that does not match'?
Elige una opción para comprobar tu respuesta.
Respuesta correcta: D)forfeit
💡 Explicación
Heritage and tourism discourse at C1+ treats credibility as something held conditionally and lost when a claim is checked. Reading the final clause first identifies the audience that judges the guides, and that is what determines the verb.
Ver respuesta
Respuesta correcta: D)forfeit
A)secure'Secure' is the opposite of what the sentence describes, since the mismatch appears only when readers check the facts. Nothing in it suggests the guides became more trusted.
B)entertain'Entertain' means to consider an idea or to host people, and neither sense fits a clause about visitors forming an opinion. The sentence is about credibility being lost, not about hospitality.
C)postpone'Postpone' means to move something to a later time, and the clause describes a consequence that has already happened to the guides' reputation. Nothing here is delayed.
D)forfeit'Forfeit' means to lose something one had been entitled to hold, and the clause describes a loss of credibility with a specific audience. The later discovery that the account differs is what the trust was worth and no longer is.

Respuesta correcta: D)strips
💡 Explicación
Heritage writing at C1+ makes a sharp distinction between replacing something and destroying its history. Here the clause after the blank names the record as the casualty, and that is a removal rather than a concealment or a repair.
Ver respuesta
Respuesta correcta: D)strips
A)restores'Restores' is the opposite of what the sentence describes, since replacing original beams is what makes the loss irreversible. The word would contradict the clause about removing the record.
B)conceals'Conceal' means to hide, and nothing in the sentence is being kept from view. The new beams are visible; what has gone is the original material, which is a removal rather than a concealment.
C)extends'Extend' means to make longer, and the sentence is about loss rather than addition. Nothing in it suggests the building gained anything by the substitution.
D)strips'Strips' means removes something from something, and the sentence describes a building losing the evidence embedded in its materials. The clause 'of the record it was supposed to preserve' names precisely what has been taken away.

Respuesta correcta: A)flatten
💡 Explicación
The pair of words in this sentence, 'flatten' and 'add to', sets up the contrast the item is testing. At C1+ the deciding step is noticing that the described act reduces complexity rather than colouring it, which rules out a verb for exaggeration.
Ver respuesta
Respuesta correcta: A)flatten
A)flatten'Flatten' means to reduce something to a single flat level, which is what happens when a complex history is described in one evaluative label. The contrast with 'adding to it' confirms that nothing is being contributed.
B)chronicle'Chronicle' means to record events in order, and the sentence describes a description that departs from the record rather than supplying one. Nothing in the clause suggests a careful account.
C)authenticate'Authenticate' means to confirm something is genuine, and the coaches are presenting a label that flattens the site rather than verifying it. No question of authenticity arises in the clause.
D)dramatise'Dramatise' means to present something in an exaggerated form for effect, which would add a layer of interpretation. The sentence says nothing is added; the history is lost rather than embellished.

A guide to tourism & heritage in Pereira writes: 'The colonial quarter is remarkably well preserved, though the newer districts are conspicuously neglected.' What does the shift from 'remarkably' to 'conspicuously' do to the evaluation?
Elige una opción para comprobar tu respuesta.
Respuesta correcta: C)It praises the first area and signals that the second should be looked at closely.
💡 Explicación
Degree adverbs do more than amplify: they select a stance. 'Remarkably' presupposes something expected and finds it better, whereas 'conspicuously' flags something anomalous and demanding attention. Reading the pair in sequence, rather than treating each adverb as a stylistic ornament, is what lets a C1+ reader extract the argument rather than just the tone.
Ver respuesta
Respuesta correcta: C)It praises the first area and signals that the second should be looked at closely.
A)It intensifies the praise for both areas equally.'Conspicuously' does not praise the newer districts; it marks them as standing out in a way that is not welcome. Reading both adverbs as equally approving erases the contrast the guide builds.
B)It softens the criticism of the second area by balancing it against the first.The comparison sharpens rather than softens the criticism, because the excellence of the first area makes the neglect of the second more glaring. 'Conspicuously' points at a problem rather than smoothing it over.
C)It praises the first area and signals that the second should be looked at closely.'Remarkably' intensifies approval of the well-preserved quarter, while 'conspicuously' shifts to something standing out for the wrong reason. Used together the pair directs the reader's attention rather than flattening the judgement into praise.
D)It removes the need for evidence, since the adjectives carry the judgement on their own.The adjectives carry emphasis, not proof. They make the claim more persuasive rhetorically while leaving the reader still dependent on the details behind the judgement.

The streets are made of stone, the houses are white with green doors, and there are no tall buildings anywhere. In the afternoon I walked the Camino Real to Guane, an old path built by indigenous people and later repaired in the nineteenth century. It took me two hours, and I did not see a single car.

Discussing tourism & heritage in Pereira.
A heritage panel in Pereira argues that the city's restored facades are 'strikingly uniform', with every balcony rebuilt to the same design. Why does the panel object to that adjective?
Elige una opción para comprobar tu respuesta.
Respuesta correcta: B)Because uniform restoration erases the evidence of how the buildings actually developed.
💡 Explicación
Evaluative adverbs like 'strikingly' carry an implied comparison: something is striking precisely because it departs from what is expected. When a panel uses the word approvingly and then objects, the conflict is diagnostic. Students at C1+ should read such an adverb as an invitation to ask which expectation is being measured against, since that is where the argument usually lives.
Ver respuesta
Respuesta correcta: B)Because uniform restoration erases the evidence of how the buildings actually developed.
A)Because uniformity makes the buildings easier and cheaper to restore.Ease and cost are not raised as concerns in the sentence, and efficient restoration would not by itself be a fault for a panel. The complaint concerns what is lost from the record, not what is spent.
B)Because uniform restoration erases the evidence of how the buildings actually developed.When every element is reconstructed identically, the record of successive periods is lost with the original fabric. The panel is objecting to what 'strikingly uniform' makes invisible, not to the quality of the workmanship.
C)Because 'strikingly' is too informal a word for a technical report.The register of the adjective is not what the panel objects to; nothing in the passage contrasts formal with informal wording. Reading the objection as stylistic would miss that the criticism is about historical evidence.
D)Because the panel believes the original facades were never uniform.The panel does not dispute that the originals varied; it objects to what was done afterwards. Saying the originals were uniform answers a question the sentence never raises and misses the argument entirely.

The landscape was not chosen for one beautiful building, but for the way families have adapted coffee farming to steep mountains for more than a century. During your visit, you will see how the beans are picked by hand, washed and dried in the sun.

A)She should go on a Monday holiday, when entry is free.Incorrect. The museum is 'closed on Mondays, including public holidays', so she cannot visit at all on that day.
B)She must book in advance because she is alone.Incorrect. Booking is required only for groups of more than ten people, not for an individual visitor.

Elige una opción para comprobar tu respuesta.
Respuesta correcta: C)were
💡 Explicación
The choice between the simple past passive ('were visited') and the present perfect passive ('have been visited') turns on whether the action is presented as finished or still relevant. With 'had almost forgotten' anchoring the viewpoint in the past, the simple past is the form that fits, and students who reach for the perfect lose that anchoring.
Ver respuesta
Respuesta correcta: C)were
A)areThe present passive would claim the visiting is still going on, which contradicts 'had almost forgotten', a past perfect located before the guiding resumed. The relevant pattern sits entirely in the past.
B)have beenThe present perfect passive would leave the visiting open to the present, but the sentence is anchored by a past perfect auxiliary. A completed extent of years has to be expressed in the past, not in a form extending to now.
C)were'The restored balconies were visited' is the simple past passive: the balconies receive the action and the sentence reports a completed pattern of events. The rare visiting is what the 'so rarely' clause builds on, and it is compatible with a simple past form.
D)being'Being visited' is a non-finite form and cannot stand as the main verb of the clause on its own. It would need a modal or an auxiliary to carry the tense, and none is supplied before the gap.

Elige una opción para comprobar tu respuesta.
Respuesta correcta: B)most
💡 Explicación
Superlatives take the definite article before the adjective, so 'the most visited' is both the most frequent and the most economical way to rank a set. Students frequently over-mark the superlative with '-est' or reach for a quantifier like 'much' when the comparison concerns frequency rather than amount, and both errors are targeted by the distractors here.
Ver respuesta
Respuesta correcta: B)most
A)mostestEnglish has no superlative ending '-est' on top of 'most'; doubling the marker produces a form that is not part of the language. The article is required, but the degree word itself stops at 'most'.
B)mostThe superlative takes the definite article: 'the most visited'. The plural museums make the correct form 'most' and never 'the mostest'. 'Most' also pairs naturally with 'by far', which reinforces the comparison.
C)much'Much' compares quantity rather than frequency, so 'the much visited' would suggest the museums receive a large amount of visiting rather than that one of them is visited most often. The comparison is between museums, which needs a superlative.
D)the mostestAlthough the article belongs there, appending '-est' to an adverb of degree is not licensed; 'the most' already carries the superlative meaning on its own. Students who do this are treating the adjective 'visited' as though it were taking the ending instead.

Respuesta correcta: C)otherwise
💡 Explicación
Verbs of saying and thinking govern a clause rather than a phrase, which is why a linker cannot follow them here. At C1+ students should treat the blank as something that has to mean on its own, and 'otherwise' is the only option that can carry the content the marks are said to convey.
Ver respuesta
Respuesta correcta: C)otherwise
A)so'So' would introduce a result clause, and that would give the sentence two finite verbs with the second without a subject. The blank has to complete a noun clause that the verb 'say' already governs.
B)because'Because' introduces a reason clause, which would likewise leave a second finite verb with no subject of its own. It also carries no content that could stand for the casting marks' claim.
C)otherwise'Otherwise' stands for the opposite of what the guide has just asserted, which is precisely what the casting marks contradict. A nominal clause object after a verb of saying needs a word that carries meaning rather than one that introduces another clause.
D)if'If' introduces a conditional clause, and the sentence already contains a contrast established by 'although'. Adding another clause would break the structure the reporting verb requires.

A)fewest'Fewest' is the superlative and requires 'in' rather than 'than'. Using it here would contradict the comparative structure that 'than' demands.
B)lessA comparative adverb is required because the sentence compares two quantities, and 'less' is the form that pairs with the following 'than'. The clause about the museum taking more visitors confirms the direction of the comparison.
C)little'Little' is the positive form, not the comparative, so the sentence would offer no comparison at all. The 'than' clause makes a comparative mandatory here.

A time expression such as 'since' usually identifies the tense before the auxiliary does. At C1+ students should read that phrase first, and then supply the form it requires, including the 'been' that marks the passive.
Ver respuesta
Respuesta correcta: B)have not been
A)were not'Were not' is the past passive, which locates the failure at a single past moment. 'Since' needs a period extending up to the present, and the upper floors are still unpainted now.
B)have not been'Have not been' plus the past participle is the present perfect passive, which is what pairs with 'since' to link a past event to a present state. The clause about the green still being there confirms the repainting did not happen.
C)have not'Have not' without the participle would leave the sentence without a main verb after the subject. The passive also requires 'been' before the participle, so both elements are missing.
D)will not be'Will not be' projects into the future, and nothing in the sentence predicts any repainting. The issue is that the repainting did not happen at any point since the funding ended.

A)They are literally looking for something in the trees of Bogotá.Incorrect. This reads the idiom word for word; nobody in the debate is searching any trees, because the phrase is figurative and describes a mistaken strategy.
B)The approach is too noisy and aggressive.Incorrect. 'Barking' here does not describe loud or aggressive behaviour; the idiom is about aiming at the wrong target, not about the tone of the discussion.
C)A new environmental project involving trees should be started.Incorrect. The speaker is criticising the current approach, not proposing a new project; 'tree' is part of a fixed expression and has no literal meaning here.
D)The current strategy is directed towards the wrong objective.Correct. 'Bark up the wrong tree' comes from hunting dogs barking at a tree the animal is not in, so it means putting effort into the wrong cause or the wrong solution.

A)She is stating a measurable trend while explicitly marking it as an observation rather than proven evidence.The final clause separates a rule she has noticed from a finding she can demonstrate. She reports the figure and limits its authority at the same time, which is what the two phrases together accomplish.
B)She is retracting a claim she had already proved.Nothing withdraws a proven claim; a retraction would say it proved false. She is qualifying a claim she never presented as established, so nothing is taken back.
C)She is insisting the coach parks caused the increase.The sentence reports that the increase followed the opening without asserting a cause. Naming the coach parks as the cause would be an inference the wording does not license.
D)She is asking the other speakers to publish the visitor figures.The final clause describes what she is doing with her own statement. There is no imperative, no question and no reference to anyone else's data in the quotation.

Respuesta correcta: B)The hotel has both positive and negative effects.
A)The hotel is dangerous because it sells weapons to tourists.Incorrect. This interprets 'sword' literally; the idiom is about mixed consequences, not real weapons.
B)The hotel has both positive and negative effects.Correct. A 'double-edged sword' is something with good and bad consequences; Daniel gives one benefit (jobs) and two problems (traffic and noise).
C)The hotel is completely good for the city.Incorrect. Daniel mentions traffic and noise as problems, so he does not think the hotel is only positive.
D)He agrees that the hotel completely ruins the view.Incorrect. He does not repeat the complaint about the view; instead he balances a benefit against other problems.

Respuesta correcta: D)Waiting to see the conditions and deciding at the last moment.
💡 Explicación
'Play it by ear' means to act without a fixed plan and respond to circumstances. The receptionist's reason ('The weather here changes a lot') and the suggestion 'decide in the morning' confirm the meaning. 'Why don't you...?' is also a polite way to make a suggestion in English, a useful pragmatic form.

Respuesta correcta: D)Waiting to see the conditions and deciding at the last moment.
A)Listening to music during the walk in the valley.Incorrect. This is a literal interpretation of 'ear'; the expression is about flexible decisions, not music.
B)Cancelling the trip because it will certainly rain.Incorrect. The receptionist says the weather changes a lot, so she does not know it will rain; she recommends waiting, not cancelling.
C)Booking a fixed tour for tomorrow immediately.Incorrect. A fixed booking is the opposite of her advice, which is to decide later depending on the weather.
D)Waiting to see the conditions and deciding at the last moment.Correct. 'Play it by ear' means to decide according to the situation instead of planning in advance; she suggests deciding in the morning when the weather is known.
