Preview: Explanations
1."could have gone"(a)
Use 'could have gone' to express an unrealized past possibility — visiting those places was an option, but the speaker chose to stay home. 'Would have gone' requires a condition (e.g., 'if someone had invited me'). 'Must have gone' would mean a deduction that the speaker DID go, which contradicts the context.
2."would have bought"(b)
Use 'would have + past participle' for the hypothetical result in a third conditional sentence. The speaker didn't know about the sale, so they didn't buy a laptop — but in the imagined situation where they knew, they WOULD have bought one.
3."could have finished"(c)
Use 'could have finished' to express an unrealized past ability. She had the ability to finish easily, but never entered a marathon, so the ability was never used. 'Would have finished' requires a specific condition, and 'never entering' is a choice, not a conditional scenario.
4."would have lent"(d)
Use 'would have lent' to describe what someone was willing to do but didn't end up doing because the offer was declined. He was willing and ready — he would have done it if the speaker had accepted.
5."could have taken"(a)
Use 'could have taken' for an option that was available but not chosen. Taking a taxi or a bus was possible, but they chose to walk. 'Should have taken' would imply criticism of the decision to walk, but there's no regret here.
