Past Simple

Respuesta correcta: A) visited

• A) visitedCorrect. A regular verb in the past simple takes the -ed ending, and 'last Saturday' fixes the action in a finished past period.
• B) was visitWrong. 'Was visit' lacks the past participle required after the auxiliary 'was'.
• C) visitingWrong. 'Visiting' is a gerund and cannot serve as the finite verb of a clause with 'I'.
• D) visitsWrong. 'Visits' is the third person singular present form, which cannot follow the pronoun 'I' in the past.

Respuesta correcta: B) travelled

• A) travelWrong. 'Travel' is the base form and cannot be the past simple of a completed journey.
• B) travelledCorrect. British and Peruvian spelling doubles the final consonant, so the past simple is 'travelled' for a single 'l' base form.
• C) travellingWrong. 'Travelling' is the gerund form used in continuous structures, not in the past simple.
• D) travelsWrong. 'Travels' is the third person singular present and does not agree with the plural subject 'we'.

Respuesta correcta: C) bought

• A) buiedWrong. 'Buied' attempts a -ed ending and does not correspond to any standard irregular pattern.
• B) buyedWrong. 'Buyed' is not an English word; the past simple of 'buy' is irregular and adds no suffix.
• C) boughtCorrect. 'Buy' is irregular, and its past simple is 'bought', which must be memorised as one of the main irregular groups.
• D) buyWrong. 'Buy' is the base form and would be required only after a modal or an auxiliary.

Respuesta correcta: D) He didn't see the thief.

• A) He not saw the thief.Wrong. 'Not' cannot stand alone before a bare verb in standard English; it must follow an auxiliary.
• B) He didn't saw the thief.Wrong. After 'did' the verb must be the base form; 'saw' after 'did' is a double marking of the past.
• C) He doesn't see the thief.Wrong. 'Doesn't' is present tense negation and would place the witnessing at the present moment.
• D) He didn't see the thief.Correct. A negative past simple uses the auxiliary 'did' plus 'not' plus the base form, so the verb stays in its original form.

Respuesta correcta: A) Did you finish the report?

• A) Did you finish the report?Correct. A yes/no question in the past simple begins with the auxiliary 'did' and is followed by the subject and the base form.
• B) You did finish the report?Wrong. As written this is a statement rather than a question, and the inversion required by a question is missing.
• C) Did you finished the report?Wrong. The past form 'finished' must not follow 'did'; the auxiliary already carries the tense.
• D) Do you finish the report?Wrong. 'Do' is the present auxiliary and cannot be used to ask about a completed past action.

Respuesta correcta: B) broke

• A) breakedWrong. 'Breaked' does not exist in English; the verb 'break' is fully irregular.
• B) brokeCorrect. 'Break' is irregular and its past simple is 'broke', following the internal vowel change pattern.
• C) brokenWrong. 'Broken' is the past participle, which would appear after 'have' or 'been', not as the past simple.
• D) brokedWrong. 'Broked' follows no standard inflection pattern for this verb.

Respuesta correcta: C) We were going to visit Ayacucho, but we didn't go.

• A) We were go to visit Ayacucho, but we didn't went.Wrong. After 'were' the verb must be the gerund, and the second clause after 'did' must use the base form.
• B) We are going to visit Ayacucho, but we don't go.Wrong. 'Are going to' states a present or future intention, which does not match a plan that belongs to the past.
• C) We were going to visit Ayacucho, but we didn't go.Correct. 'Were going to' expresses an intention formed in the past, and the second clause uses the past simple for the outcome that failed.
• D) We went to visit Ayacucho, but we don't go.Wrong. 'Went' states that the visit did happen, which contradicts the report of an unfulfilled plan.

Respuesta correcta: D) The class ended and then it was empty.

• A) The class ended and then it empties.Wrong. 'Empties' is present tense; a sequence of completed past events needs the past simple or past continuous.
• B) The class ends and then it was empty.Wrong. 'Ends' is present tense and cannot join two past events in sequence.
• C) The class ended and then it was emptying.Wrong. 'Was emptying' describes an action in progress rather than the resulting state of the room.
• D) The class ended and then it was empty.Correct. The class ending is the past simple action and the resulting condition is a state described in the past, which 'was empty' expresses.

Respuesta correcta: A) She never went to the library on Sundays.

• A) She never went to the library on Sundays.Correct. The adverb 'never' already carries the negative meaning, so no extra auxiliary is needed and the past simple follows directly.
• B) She went never to the library on Sundays.Wrong. Placing 'never' after the verb changes the emphasis and is not the standard word order for this negation.
• C) She never gone to the library on Sundays.Wrong. 'Never' cannot be followed directly by a past participle such as 'gone' in simple negative sentences.
• D) She never goes to the library on Sundays.Wrong. 'Never goes' is present tense, which contradicts the reconstructed past described in the interview.

Respuesta correcta: B) She studied medicine in Lima.

• A) She studyed medicine in Lima.Wrong. 'Studyed' keeps the -y and adds -ed, which is not how this spelling pattern inflects.
• B) She studied medicine in Lima.Correct. When a verb ending in consonant plus 'y' is made past, the -y changes to -i and -ed is added, giving 'studied'.
• C) She studies medicine in Lima.Wrong. 'Studies' is the third person singular present and does not describe a completed course of study.
• D) She studdied medicine in Lima.Wrong. 'Studdied' doubles the final consonant, a rule that applies only after a single vowel.

Respuesta correcta: C) cancelled

• A) canceldWrong. 'Canceld' drops the required doubling and produces a non-standard form.
• B) canceledWrong. 'Cancelled' with one 'l' is a frequent error; doubling is required in this spelling of the word.
• C) cancelledCorrect. With a single 'l' and the stress on the final syllable, the -ed ending is written with a double 'l' in the standard form.
• D) cancellingWrong. 'Cancelling' is the gerund, which would require an auxiliary before it.

Respuesta correcta: D) After the strike ended, the trains started again.

• A) After the strike ended, the trains are starting again.Wrong. 'Are starting again' is present continuous, which describes an action still in progress rather than a completed sequence.
• B) After the strike is ending, the trains started again.Wrong. 'Is ending' is present continuous, which cannot precede a past simple main event in a past sequence.
• C) After the strike ended, the trains start again.Wrong. 'Start again' is present tense and cannot continue a sequence that is entirely in the past.
• D) After the strike ended, the trains started again.Correct. In a sequence of completed past events joined by 'after', both events take the past simple.

Respuesta correcta: A) We visited the museum twice last year; we usually visited the coast in January.

• A) We visited the museum twice last year; we usually visited the coast in January.Correct. 'Last year' fixes the finished time for the visit and 'usually' marks the repeated January pattern, both in the past simple.
• B) We have visited the museum twice last year; we usually visit the coast in January.Wrong. 'Have visited' is the present perfect, which cannot be followed by 'last year' because that time is finished.
• C) We visited the museum twice last year; we usually are visiting the coast in January.Wrong. 'Usually are visiting' misuses the continuous, since a repeated January habit is expressed in the past simple.
• D) We visit the museum twice last year; we usually visit the coast in January.Wrong. 'We visit' in the simple present cannot be combined with the finished time expression 'last year'.

Respuesta correcta: B) Did you decide to study abroad?

• A) Do you decide to study abroad?Wrong. 'Do' asks about a present or general decision, not one taken last week.
• B) Did you decide to study abroad?Correct. 'Did' inverts to the front of the question and 'decide' stays in its base form because the auxiliary carries the past tense.
• C) You did decide to study abroad?Wrong. This is a statement, and it lacks the inversion that a yes/no question requires.
• D) Did you decided to study abroad?Wrong. The past form 'decided' must not follow 'did' in a question any more than in a statement.

Respuesta correcta: C) She accepted the offer on Friday afternoon.

• A) She accepts the offer on Friday afternoon.Wrong. 'Accepts' is present tense and cannot be placed with a finished time such as Friday afternoon.
• B) She was accepting the offer on Friday afternoon.Wrong. 'Was accepting' describes an ongoing process rather than a decision that was completed at a stated moment.
• C) She accepted the offer on Friday afternoon.Correct. A decision completed at a precise past moment takes the past simple, which is the standard treatment of 'on' plus a day and time.
• D) She has accepted the offer on Friday afternoon.Wrong. 'Has accepted' cannot be used with a finished past time; that combination belongs to the present simple for now.

Respuesta correcta: D) I have finished my project last week.

• A) I am finishing my project last week.Wrong. 'Am finishing' is present continuous and has no connection to a closed past period.
• B) I had finished my project last week.Wrong. The past perfect would place the completion before another past event, and there is no earlier past reference in the sentence.
• C) I finished my project last week.Wrong. The present perfect cannot be combined with a closed past time such as 'last week'.
• D) I have finished my project last week.Correct. 'Last week' is a closed period, so the completed action must be expressed with the past simple.

Respuesta correcta: A) travelled

• A) travelledCorrect. American spelling writes the base form 'travel' and adds -ed directly, giving 'traveled' with a single consonant.
• B) travellWrong. 'Travell' is not an English word form and lacks both the base and the past inflection.
• C) travelWrong. 'Travel' is the base form and cannot serve as the past simple of a completed trip.
• D) traveledWrong. 'Travelled' is the British and Peruvian double-l form; the American newspaper keeps the single consonant.

Respuesta correcta: B) When we arrived, the ceremony already started.

• A) When we arrived, the ceremony had already started.Wrong. 'Arrived' and 'started' as two past simple events leave the order of events unstated and often imply the wrong sequence.
• B) When we arrived, the ceremony already started.Correct. The past perfect shows that the ceremony began before the moment of arrival, which is the required order of the two past events.
• C) When we were arriving, the ceremony had started already tomorrow.Wrong. 'Tomorrow' is a future time and cannot appear in a past sequence, and 'were arriving' implies duration.
• D) When we did arrive, the ceremony already has started.Wrong. The auxiliary 'did' cannot be combined with a past perfect in this structure, and 'already has started' is not a valid form.

Respuesta correcta: C) While he was packing, he suddenly remembered his passport.

• A) While he was packing, he suddenly will remember his passport.Wrong. 'Will remember' is future and would place the realisation after the moment of narration.
• B) While he will pack, he suddenly remembered his passport.Wrong. 'Will pack' is future tense and cannot form a background for a past event.
• C) While he was packing, he suddenly remembered his passport.Correct. The background action is the past continuous and the interrupting realisation is the past simple, exactly the sequence being tested.
• D) While he packs, he suddenly remembered his passport.Wrong. 'Packs' in the simple present cannot serve as a past background for 'remembered'.

Respuesta correcta: D) If I studied harder, I would have passed.

• A) If I would study harder, I had passed.Wrong. 'Would' cannot open an if-clause, and 'I had passed' would require an earlier past reference.
• B) If I studied harder, I passed.Wrong. 'I passed' states a real past result, which converts the sentence into a statement of fact rather than a hypothetical.
• C) If I had studied harder, I would have passed.Wrong. 'If I studied' plus 'would have passed' mixes the second and third conditionals and is not a standard structure.
• D) If I studied harder, I would have passed.Correct. The third conditional pairs the past perfect in the if-clause with 'would have' plus the past participle in the main clause.
