Participle Clauses

Respuesta correcta: A) Waiting for the bus, Sofia checked her phone again.

• A) Waiting for the bus, Sofia checked her phone again.Correct. 'Waiting for the bus' is a present participle phrase with an understood subject that shares Sofia with the main clause.
• B) The bus waited while Sofia checked her phone again.This uses 'while' to build a full subordinate clause, not an -ing clause, so no participle is present.
• C) Sofia was waited for the bus at the corner.Here 'was waited for' is a broken passive; the subject Sofia cannot be waited for, she waits for the bus.
• D) Sofia checked her phone again and waited for the bus.Two finite verbs joined by 'and' form a compound clause, and no participle phrase appears here.

Respuesta correcta: C) It adds a detail about how she explained the currents.

• A) It tells when she started the explanation.An -ing phrase placed before the main clause shows something simultaneous with it, not the moment it began.
• B) It explains why she needed a whiteboard.No cause is stated anywhere in the sentence, so the phrase cannot be the reason a whiteboard was needed.
• C) It adds a detail about how she explained the currents.Correct. A fronted -ing phrase with the same subject describes the manner or accompanying action of the main verb.
• D) It identifies the people she was explaining them to.The listeners are never named, and the phrase attaches to 'she' as its subject rather than to any people.

Respuesta correcta: B) a reduced relative clause with passive meaning

• A) an active clause meaning the photographs took something'Taken' is past participle form, so it is passive; the photographs cannot take anything in this context.
• B) a reduced relative clause with passive meaningCorrect. A past participle after a noun is a reduced relative clause in the passive: someone else took the photographs.
• C) a gerund clause serving as the subject of the sentenceThe noun 'photographs' is the subject of the sentence, not a gerund phrase, and no -ing form appears at all.
• D) an adverbial clause of time telling when the photos arrivedA reduced relative modifies the noun beside it; it does not give a time, and no time adverb such as 'when' is present.

Respuesta correcta: D) Arriving early, Mariana got a good seat.

• A) Early arrived, Mariana got a good seat.'Early' is an adjective, not a participle, and the clause can never start with it in this position.
• B) Having arrived early, Mariana was given a good seat.This perfect participle changes the meaning: she is no longer the one who gets the seat but the one who receives it.
• C) Arriving to early, Mariana got a good seat.'Arrive' is intransitive and never takes the preposition 'to', so this prepositional phrase is ungrammatical.
• D) Arriving early, Mariana got a good seat.Correct. The reason clause 'because she arrived early' becomes the -ing clause 'arriving early' with the same subject.

Respuesta correcta: A) Having finished both exams, Diego submitted the scholarship form.

• A) Having finished both exams, Diego submitted the scholarship form.Correct. 'Having finished' is the perfect participle, so it marks an action completed before the main verb began.
• B) Finishing both exams, Diego has submitted the scholarship form.A present participle followed by a present perfect wrongly suggests Diego is still sending the form now.
• C) Being finished both exams, Diego submitted the form.'Being finished' makes Diego the thing being finished, which reverses who does the action and is not the meaning.
• D) Finished both exams, Diego submitted the form.'Finished' on its own is a bare past participle; the action would be read as an absolute phrase with no linked subject.

Respuesta correcta: B) A reduced relative clause describing which farmers are meant.

• A) A participle clause of reason explaining why they talk.No cause is stated in the sentence, and the phrase describes farmers rather than giving a reason for talking.
• B) A reduced relative clause describing which farmers are meant.Correct. The -ing phrase follows the noun 'Farmers' and narrows which farmers are talking, so it is a reduced relative.
• C) An absolute construction with its own subject and verb.An absolute construction stands alone with its own subject; here the phrase is attached to the noun 'Farmers'.
• D) A gerund clause serving as the subject of 'talk'.A gerund clause would work as the subject, but 'Farmers working in the shade' already fills that subject slot.

Respuesta correcta: D) Walking along the road, the landslide looked enormous.

• A) Driving in the rain, the driver saw the landslide ahead.This is correct: the driver is the understood subject of 'Driving' and also the subject of 'saw'.
• B) The landslide, seen from the road, blocked both lanes.This is correct and the phrase is a reduced relative in the passive, so no subject is needed after 'landslide'.
• C) Hitting the road at dawn, the landslide damaged a bridge.Here the landslide, not a person, is doing the hitting, so the understood subject of the participle matches 'landslide'.
• D) Walking along the road, the landslide looked enormous.Wrong. A landslide cannot walk; the participle dangles because its implied subject does not match the main subject.

Respuesta correcta: A) With the rain pouring down, the fishermen stayed in port.

• A) With the rain pouring down, the fishermen stayed in port.Correct. The pattern is 'with' plus noun plus -ing, which is an absolute construction adding accompanying circumstance.
• B) With rain to pour down, the fishermen stayed in port.An infinitive 'to pour' after 'with' can only carry purpose, so it fails to show the rain actually happening.
• C) With the rain poured down, the fishermen stayed in port.A past participle after 'with' suggests the rain had finished pouring, which changes when the storm was occurring.
• D) With pouring the rain, the fishermen stayed in port.A bare noun cannot follow 'with' and then take an object like 'the rain'; the noun must sit before the participle.

Respuesta correcta: C) the crater that was photographed in 2019

• A) the crater which photographed in 2019An active 'which photographed' claims the crater took the picture, and a bare relative pronoun needs a full verb here.
• B) the crater what was photographed in 2019'What' cannot introduce a relative clause in English; it is only a question or a free relative subject.
• C) the crater that was photographed in 2019Correct. The past participle 'photographed' is passive, so the full form needs 'was' plus 'that'.
• D) the crater which is photographing in 2019'Is photographing' is present progressive and passive in meaning, but it does not match the past participle form.

Respuesta correcta: B) The report written by a student was published on Friday.

• A) The report, which was written by a student, was published on Friday.This keeps the full relative clause with 'which was written', so nothing has been reduced to a participle phrase.
• B) The report written by a student was published on Friday.Correct. The passive relative clause contracts to the reduced form 'written by a student', with the noun as its object.
• C) The report writing by a student was published on Friday.'Writing by a student' is active in form, so it wrongly claims the report itself wrote something.
• D) The report was write by a student was published on Friday.'Was write' is not a valid verb form; the past participle 'written' is needed after 'was'.

Respuesta correcta: C) Riding uphill, I felt the chain come off my bike.

• A) Uphill, ridden, my chain came off.'Ridden' is a past participle used passively here, but the scattered order leaves the clause with no real subject.
• B) Riding uphill was what made my chain come off.This makes the activity itself the subject and changes the meaning into a claim about what caused the failure.
• C) Riding uphill, I felt the chain come off my bike.Correct. Naming 'I' as the subject of the participle removes the dangler and keeps the rider as the doer.
• D) Being ridden uphill, the chain came off my bike.This reverses the roles: it claims the chain was being ridden, yet the chain is the subject of 'came off'.

Respuesta correcta: A) With the vegetables washed, the onions were chopped.

• A) With the vegetables washed, the onions were chopped.Correct. 'With the vegetables washed' is an absolute structure, so the onions and the vegetables are two subjects.
• B) Having washed the vegetables, the onions were chopped.The perfect participle implies the onions washed themselves, but the main subject is 'the onions', so this dangles.
• C) Washing the vegetables, I chopped the onions.This is an ordinary participle clause: one subject, 'I', acts in both the -ing phrase and the main verb.
• D) The vegetables washed, I chopped the onions.The phrase 'the vegetables washed' is a passive absolute that has no linking word and cannot stand before the main clause this way.

Respuesta correcta: D) Having trained the volunteers, Carla began the workshop.

• A) Having trained the volunteers, the workshop began at eight.The workshop cannot be the one who trained the volunteers, so the implied subject of the participle dangles.
• B) Having trained, the volunteers the workshop.The phrase is ungrammatical: 'having trained' has no object and the main verb is missing entirely.
• C) The volunteers, having trained each other, the workshop began.Two finite subjects clash in one clause, and the second half lacks a main verb to pair with 'began'.
• D) Having trained the volunteers, Carla began the workshop.Correct. 'Carla' is the subject of both 'Having trained' and 'began', so the perfect participle is properly anchored.

Respuesta correcta: B) As the fisherman caught the net, the tide rose quickly.

• A) Catching the net, the tide rose quickly.This dangles: the tide cannot be the one catching a net, so the participle has no matching subject.
• B) As the fisherman caught the net, the tide rose quickly.Correct. Recasting the phrase as a full subordinate clause gives the fisherman an explicit subject, so nothing dangles.
• C) The net caught, the tide rose quickly.This is an absolute construction, so the fisherman disappears as the doer and the net becomes the focus.
• D) Catching the net was done as the tide rose.This nominalizes the action with 'was done', which hides who caught the net and drops the original emphasis.

Respuesta correcta: C) The car, because it is the subject of the main verb 'passed'.

• A) Both the car and the cyclists, because the sentence mentions both.The participle takes only one implied subject, and it cannot refer to two different nouns at the same time.
• B) The cyclists, because they are named nearest to the participle.Distance is not the deciding factor; the attachment rule follows the subject of the main verb, not the closest noun.
• C) The car, because it is the subject of the main verb 'passed'.Correct. A fronted participle phrase attaches to the main clause subject, so the car is understood as the one racing.
• D) Nobody is racing, since the phrase adds no real information.The phrase carries a clear meaning, and it also creates a misleading impression that a car was doing the racing.

Respuesta correcta: D) Performing by a guide, the walk through the reserve lasts two hours.

• A) Protected for decades, the mangroves now shelter young fish.This is correct: a past participle in the passive shows the mangroves were protected by someone else.
• B) Being protected by the reserve, the mangroves shelter young fish.This is correct too: 'being protected' is the passive continuous form and keeps both subjects in view.
• C) Protected by trained staff, the trails are safe for visitors.This is correct: the passive participle 'Protected' takes the trails as its subject and the trails are protected.
• D) Performing by a guide, the walk through the reserve lasts two hours.Wrong. 'By a guide' requires a passive participle, so 'performed' would be right while 'performing' is not.

Respuesta correcta: B) Using recycled materials, the students built planters for the park.

• A) Used recycled materials, the students built planters for the park.'Used' is a past participle and would make the students the thing being used, reversing the roles entirely.
• B) Using recycled materials, the students built planters for the park.Correct. The students are the active subject of both 'Using' and 'built', so the participle clause is anchored.
• C) Having using recycled materials, planters were built for the park.'Having using' is not a valid form; the perfect participle needs 'having used', and the participle subject dangles.
• D) Using recycled materials, planters was built for the park.Here the planters become the subject of 'Using', so the planters recycle something, and the verb also disagrees.

Respuesta correcta: C) Having collected the bottles, the crew filled the bags and left.

• A) Collecting the bottles and having filled the bags, the crew left.Putting the present participle first reverses the real sequence, since filling the bags must happen after collecting.
• B) Collecting bottles, the crew had filled the bags and left.A present participle paired with a past perfect leaves the aspect unsettled and blurs which action came first.
• C) Having collected the bottles, the crew filled the bags and left.Correct. The perfect participle comes first because collecting the bottles finished before the bags were filled.
• D) The bottles collected, the crew filled the bags and left.This is a passive absolute with the bottles as subject, so it loses the crew as the doer of the collecting.

Respuesta correcta: A) Having lost most of the dry forest, the region now floods each season.

• A) Having lost most of the dry forest, the region now floods each season.Correct. The perfect participle and the main verb share the subject 'the region', so nothing dangles.
• B) Losing the dry forest, the soil washes into the rivers.This dangles because the soil cannot lose forest; the real doer, the region, is missing from the participle's subject.
• C) The forest lost, the region now floods every rainy season.This is a passive absolute where the forest becomes the subject, so the region is no longer presented as the agent.
• D) Losing most of the dry forest, the rain fell on the whole valley.This dangles because the rain cannot lose forest, yet 'the rain' is the subject of the main verb 'fell'.

Respuesta correcta: D) Having sampled the river for a year, the team proved the change was real.

• A) Sampling the river for a year, the data were conclusive.This dangles: 'the data' cannot sample a river, so the phrase leaves the research team unnamed.
• B) Having sampled the river, the data proved the species had changed.This dangles again: the subject is 'the data', yet the perfect participle implies the data did the sampling.
• C) Sampling the river, the team had collected samples for a year.A present participle with a past perfect leaves the aspect confused and mixes two views of the same activity.
• D) Having sampled the river for a year, the team proved the change was real.Correct. The team is the subject of both parts, the perfect participle shows the earlier year, and the claim stays clear.
