Select all that apply. Which sentences correctly match the past-necessity form to the explicit fact about whether the action happened?
I left the tripod in the van and took no photographs, so I needn't have carried it uphill.
The door was already open, so I didn't need to bring the key and left it at home.✓پاسخ درست
I bought the premium map and later found a free one, so I needn't to have bought it.
We warmed the soup, then learned everyone had eaten, so we needn't have warmed it.✓پاسخ درست
توضیح
The key stayed at home because the open door made bringing it unnecessary, so didn't need to bring matches an action that was not performed. The soup was warmed unnecessarily, so needn't have warmed correctly marks a completed action; the tripod statement conflicts with leaving it behind, and needn't to have is malformed.
