Mixed Realities

Respuesta correcta: C) had paid / would have

• A) paid / would have'paid' in the if-clause would be the second conditional, which treats the French class as a present hypothetical rather than a past one.
• B) had paid / would have had'Would have had' would put the result in the past too, but the sentence ends in 'now', which is present.
• C) had paid / would haveThe condition is in the past ('three years ago'), so the if-clause takes the past perfect 'had paid', and the present result takes 'would have'.
• D) paid / will have'Will have' states a future certainty, and 'paid' ignores the past time reference.

Respuesta correcta: D) weren't / would have gone

• A) wasn't / would go'Wasn't / would go' is the second conditional: condition and result in the present, but the party is 'last night'.
• B) hadn't been / would have gone'Hadn't been' would put the condition in the past, but the sentence describes how he is now.
• C) isn't / went'Isn't' contradicts 'last night', and 'went' is plain past rather than a hypothetical.
• D) weren't / would have goneThe shyness is a present state ('is so shy') and the party is past ('last night'), so the result must be 'would have gone'.

Respuesta correcta: D) would have taken / spoke

• A) would take / spoke'Would take / spoke' is the second conditional: condition and result in the present, but the degree was taken in the past.
• B) would have taken / had spokenBoth halves would then be past: 'had spoken' plus 'would have taken', which does not match the sentence's present result.
• C) took / speak'Took / speak' is ungrammatical: the second verb would need an infinitive marker.
• D) would have taken / spokeThe condition mixes a past fact ('spoke', no past marker) with a present result ('would have taken'), which is the third-to-second mixed pattern.

Respuesta correcta: B) had passed / would be

• A) passed / would be'Passed / would be' is the second conditional, but the law was passed in 2010, a fixed past moment.
• B) had passed / would beThe passing of the law is a past fact and the present consequence is 'would be', which is the mixed conditional pattern.
• C) had passed / would have been'Would have been' would place the result in the past as well, but 'today' is present.
• D) passed / will be'Will be' states a future certainty, and 'passed' ignores the past time reference.

Respuesta correcta: D) had eaten / wouldn't have

• A) ate / wouldn't have'Ate / wouldn't have' is the second conditional, but the sentence refers to a past stretch of childhood.
• B) had eaten / wouldn't have had'Wouldn't have had' would put the health problems in the past too, but they persist now.
• C) were eating / won't have'Were eating' is progressive and cannot open an if-clause here, and 'won't have' is a future prediction.
• D) had eaten / wouldn't haveThe eating happened in the past ('had eaten') and the health problems are present now, so the result uses present 'wouldn't have'.

Respuesta correcta: D) would be / had bought

• A) would be / bought'Would be / bought' is the second conditional, but the software was bought at a fixed point in the past.
• B) would have been / had bought'Would have been finished' would place the completion in the past, but 'by now' refers to the present.
• C) will be / had bought'Will be' predicts the future, but 'by now' refers to the present.
• D) would be / had boughtThe purchase is a past fact ('had bought') and 'by now' looks at the present, so the result is 'would be finished'.

Respuesta correcta: B) hadn't been born / wouldn't

• A) wasn't born / wouldn't'Wasn't born / wouldn't' is the second conditional, treating both the birth and the result as present hypotheticals.
• B) hadn't been born / wouldn'tThe birth is a past fact, so the condition is 'hadn't been born', while the Spanish study would still be a present requirement.
• C) am not born / won't'Am not born' is present tense, which contradicts the past fact of having been born.
• D) hadn't been born / wouldn't have'Wouldn't have had to' would describe a past obligation, but studying Spanish is a condition for the present.

Respuesta correcta: A) would be / hadn't built

• A) would be / hadn't builtBuilding the walls happened in the past ('hadn't built') and the flooding is a present state, so 'would be' completes the pattern.
• B) were / hadn't built'Were / hadn't built' mixes a past result with a second conditional form; 'would be' is needed for a present state.
• C) would be / didn't build'Didn't build' is the second conditional, which ignores the past time reference 'last year'.
• D) had been / hadn't built'Had been' would put the flooding in the past, but 'already' refers to the present situation.

Respuesta correcta: D) knew / would have saved

• A) knew / saved'Knew / saved' is the second conditional with no inversion, and it treats the outcome as present rather than past.
• B) had known / would have saved'Had known' would put the knowledge in the past, but the sentence says 'if we knew' about the present.
• C) know / would save'Know' would need a past form, and 'would save' would place the saving in the present.
• D) knew / would have savedThe cure is a hypothetical present state, so the if-clause stays simple ('knew') and the lost lives, which are past, take 'would have saved'.

Respuesta correcta: B) been / wouldn't be

• A) was / wouldn't be'Was' cannot follow an inverted 'Had', because the inversion already places the auxiliary before the subject.
• B) been / wouldn't be'Been / wouldn't be' combines the inversion 'Had been' with a present result 'wouldn't be', which is the mixed conditional the sentence needs.
• C) being / wasn't'Being' is a participle and 'wasn't' would place the result in the past, contradicting 'today'.
• D) been / wouldn't have been'Wouldn't have been' would put the tense relationship in the past, but the tension is present 'today'.

Respuesta correcta: C) would be / had designed

• A) is / designed'Is / designed' gives no inversion, which a conditional opening requires.
• B) would have been / had designed'Would have been less crowded' would place the state in the past, but 'now' refers to the present.
• C) would be / had designedThe planning happened thirty years ago, so the if-clause is past perfect, and the present crowding takes 'would be'.
• D) was / had designed'Was less crowded' states a past fact rather than a hypothetical result.

Respuesta correcta: A) Were / would be living

• A) Were / would be living'Were it not for' is the formal inversion of 'If it were not', and the result clause takes the present 'would be living'.
• B) If it was / live'If it was' would be informal and 'live' lacks the modal needed for a hypothetical present.
• C) Had / been living'Had been living' would place the result in the past, but 'right now' refers to the present.
• D) Was / would live'Was' lacks the inverted conditional structure, and 'would live' omits the progressive the sentence needs.
