Conditionals Type 2 3

Respuesta correcta: A) If I lived closer to San Juan, I would walk to school every day.

• A) If I lived closer to San Juan, I would walk to school every day.Correct. The second conditional expresses an unreal present hypothesis: past simple plus 'would' plus infinitive.
• B) If I will live closer to San Juan, I would walk to school every day.Incorrect. The 'if' clause does not take 'will'; in the second conditional it takes the past simple.
• C) If I had lived closer to San Juan, I would walk to school every day.Incorrect. 'Had lived' belongs to the third conditional, which refers to the past rather than the present.
• D) If I live closer to San Juan, I would walk to school every day.Incorrect. The present simple in the 'if' clause belongs to the first conditional, not to a present hypothesis of the second conditional.

Respuesta correcta: C) were

• A) wasIncorrect. 'Was' is possible in informal speech, but in the second conditional the formal, expected form is 'were'.
• B) amIncorrect. 'Am' is present tense and does not fit the unreal hypothesis of the second conditional.
• C) wereCorrect. In the second conditional, the verb 'to be' takes the form 'were' with any subject, even with 'I'.
• D) will beIncorrect. 'Will be' is a future form and does not fit the present hypothesis of the second conditional.

Respuesta correcta: B) had studied

• A) studiedIncorrect. 'Studied' is past simple and would belong to the second conditional, not to a past hypothesis.
• B) had studiedCorrect. The third conditional expresses a past hypothesis: 'had' plus participle in the 'if' clause.
• C) has studiedIncorrect. 'Has' is present perfect and does not fit a past action that was carried out.
• D) would studyIncorrect. 'Would study' is the result of a conditional, not the condition, so it is in the wrong place.

Respuesta correcta: D) had

• A) haveIncorrect. 'Have' is present tense and belongs to the first conditional, which expresses a real, possible condition.
• B) will haveIncorrect. 'Will have' is future and does not fit the unreal hypothesis of the second conditional.
• C) would haveIncorrect. 'Would have' is the result of the third conditional and goes in the main clause, not in the 'if' clause.
• D) hadCorrect. 'Had' is the past of 'to have' and expresses the present hypothesis of the second conditional.

Respuesta correcta: D) had known

• A) knewIncorrect. 'Knew' is past simple and belongs to the second conditional, which refers to the present.
• B) have knownIncorrect. 'Have known' is present perfect and does not express an unfulfilled past hypothesis.
• C) would knowIncorrect. 'Would know' is the result of a conditional, not the condition of the sentence.
• D) had knownCorrect. 'Had known' is the past perfect and expresses the past hypothesis of the third conditional.

Respuesta correcta: B) If I had studied medicine, I would be working in a hospital now.

• A) If I had studied medicine, I would have worked in a hospital now.Incorrect. With both clauses in the third conditional, the sentence sounds redundant and does not express the change in the present situation.
• B) If I had studied medicine, I would be working in a hospital now.Correct. This is the classic mixed structure: third conditional in the 'if' clause and second conditional in the main clause.
• C) If I studied medicine, I had been working in a hospital now.Incorrect. The order is reversed: the second conditional belongs in the main clause and the third conditional in the 'if' clause.
• D) If I would have studied medicine, I would be working in a hospital now.Incorrect. 'Would' never appears in the 'if' clause of a standard conditional.

Respuesta correcta: A) were

• A) wereCorrect. 'Were' is the second conditional form with 'I' and expresses an unreal present hypothesis.
• B) amIncorrect. 'Am' is a real present and belongs to the zero or first conditional, depending on the rest of the sentence.
• C) will beIncorrect. 'Will be' is future and does not fit the unreal present hypothesis of the second conditional.
• D) had beenIncorrect. 'Had been' belongs to the third conditional, which refers to a past hypothesis.

Respuesta correcta: C) wouldn't have broken

• A) would not have breakIncorrect. After 'would have', the verb takes the participle 'broken', not the base form 'break'.
• B) didn't brokeIncorrect. It mixes the past simple with the irregular past, and the sentence does not form a conditional.
• C) wouldn't have brokenCorrect. 'Wouldn't have' plus participle expresses regret about a past action that did not happen.
• D) don't have brokenIncorrect. 'Don't have' is present tense and does not fit a past hypothesis of the third conditional.

Respuesta correcta: C) If I were you, I would talk to the principal.

• A) If I will be you, I would talk to the principal.Incorrect. 'Will be' is future and does not fit the unreal hypothesis of this set phrase.
• B) If I am you, I would talk to the principal.Incorrect. 'Am' is a real present, and the set phrase requires 'were' to mark the hypothesis.
• C) If I were you, I would talk to the principal.Correct. 'If I were you' is a second conditional set phrase used to give advice based on an unreal hypothesis.
• D) If I had been you, I would talk to the principal.Incorrect. 'Had been' is third conditional and would place the hypothesis in the past, which is not the meaning of the sentence.

Respuesta correcta: A) had told

• A) had toldCorrect. 'Had told' is the past perfect and expresses the past hypothesis of the third conditional.
• B) would have toldIncorrect. 'Would have told' is the consequence and belongs in the main clause, not in the 'if' clause.
• C) toldIncorrect. 'Told' is past simple and belongs to the second conditional, which refers to the present.
• D) has toldIncorrect. 'Has told' is present perfect and does not fit a past hypothesis that never happened.

Respuesta correcta: D) Where would you live if you won the lottery?

• A) Where you would live if you would win the lottery?Incorrect. Question word order requires 'where' to open the sentence, and the 'if' clause cannot take 'would'.
• B) Where do you would live if you won the lottery?Incorrect. 'Do' cannot come before 'would', because both are auxiliary verbs.
• C) Where would you live if you will win the lottery?Incorrect. The 'if' clause does not take 'will'; in a second conditional it uses the past simple.
• D) Where would you live if you won the lottery?Correct. 'Would' opens the second conditional question, and the 'if' clause uses the past simple.

Respuesta correcta: B) The second refers to an unreal present and the third to an unreal past.

• A) The second is for questions and the third for statements.Incorrect. Both types appear equally in questions and statements; word order is not what distinguishes them.
• B) The second refers to an unreal present and the third to an unreal past.Correct. The second conditional projects a hypothesis onto the present, and the third conditional onto a past action that did not happen.
• C) The second uses 'would' and the third uses 'will'.Incorrect. Both use 'would'; what changes is the past simple versus 'had' plus participle in the 'if' clause.
• D) The second is formal and the third is informal.Incorrect. There is no difference in register: both are formal structures typical of written and academic language.

Respuesta correcta: B) had written

• A) would have writtenIncorrect. 'Would have written' is the hypothetical consequence and goes in the main clause.
• B) had writtenCorrect. 'Had written' expresses the hypothetical past action, and the irregular participle is required in the third conditional.
• C) wroteIncorrect. 'Wrote' is past simple and belongs to the second conditional.
• D) have writtenIncorrect. 'Have written' is present perfect and does not express an unfulfilled past hypothesis.

Respuesta correcta: D) were

• A) areIncorrect. 'Are' is a real present and belongs to the zero or first conditional, not to a hypothesis.
• B) will beIncorrect. 'Will be' is future and does not express the unreal hypothesis of the second conditional.
• C) had beenIncorrect. 'Had been' is third conditional and would place the hypothesis in a distant past that the sentence does not mention.
• D) wereCorrect. With 'you', 'were' is the second conditional form and keeps the form uniform throughout this conditional type.

Respuesta correcta: C) if

• A) unlessIncorrect. 'Unless' means 'si no' (if not), so it would completely change the meaning of the hypothetical condition.
• B) althoughIncorrect. 'Although' introduces a concession, not a condition, so it does not form a conditional.
• C) ifCorrect. 'If' introduces the past hypothesis, and the main clause with 'would have' plus participle completes the third conditional.
• D) becauseIncorrect. 'Because' introduces a real present or past cause, not the hypothesis the third conditional requires.

Respuesta correcta: A) If she studied architecture, she would work in her hometown.

• A) If she studied architecture, she would work in her hometown.Correct. Both parts follow the second conditional: past simple in the 'if' clause and 'would' plus infinitive in the main clause.
• B) If she will study architecture, she would work in her hometown.Incorrect. 'Will' does not appear in the 'if' clause of a second conditional.
• C) If she studies architecture, she would work in her hometown.Incorrect. The present simple in the 'if' clause belongs to the first conditional, which is real, not hypothetical.
• D) If she had studied architecture, she would have worked in her hometown.Incorrect. With both parts in the third conditional, the sentence sounds like regret, not a hypothesis about the present.

Respuesta correcta: A) would have passed

• A) would have passedCorrect. 'Would have' plus participle is the hypothetical consequence of the third conditional.
• B) would passIncorrect. 'Would pass' is the second conditional consequence and does not match a past perfect clause.
• C) will have passedIncorrect. 'Will have' is future perfect and does not fit a past hypothesis.
• D) would passingIncorrect. After 'would have', the verb takes the participle 'passed', never the gerund.

Respuesta correcta: D) Yes, I would have.

• A) Yes, I would have been.Incorrect. The short-answer form for the third conditional is 'would have', and the rest of the sentence does not provide the correct auxiliary.
• B) Yes, I will have.Incorrect. 'Will have' is future perfect and does not answer a question about a past hypothesis.
• C) Yes, I did.Incorrect. 'Did' answers a past simple question, not one built with 'would have'.
• D) Yes, I would have.Correct. The short answer repeats 'would have' from the question, which is the form specific to the third conditional.

Respuesta correcta: B) had

• A) will haveIncorrect. 'Will have' is future and does not fit the unreal hypothesis the sentence sets up.
• B) hadCorrect. 'Had' is the past of 'to have' and forms the present hypothesis of the second conditional.
• C) hasIncorrect. 'Has' is present tense and forms a first conditional with a real condition.
• D) had hadIncorrect. 'Had had' belongs to the third conditional with 'to have', not to the second conditional, which only needs the past simple.

Respuesta correcta: C) had gone

• A) would have goneIncorrect. 'Would have gone' is the hypothetical consequence and goes in the main clause.
• B) wentIncorrect. 'Went' is past simple and belongs to the second conditional, which refers to the present.
• C) had goneCorrect. 'Had gone' is past perfect and forms the past hypothesis of the third conditional.
• D) have goneIncorrect. 'Have gone' is present perfect and does not express an unfulfilled past hypothesis.
