Which statement correctly rewrites "They didn't let us leave the room" using "allowed"?

The statement "They didn't let us leave the room" implies that we were prohibited from leaving the room. The correct transformation centers on expressing the lack of permission in a way that matches the original sentence's meaning.

The choice "We weren't allowed to leave the room" accurately conveys the absence of permission using the word "allowed." This phrase clearly denotes that we did not have the right or opportunity to leave, aligning perfectly with the original sentiment of being denied the chance to exit the room.

The other options do not correctly represent the denial of permission. For instance, "We were allowed to leave the room" presents the opposite meaning, asserting that permission was granted, which contradicts the original statement. Similarly, while "We were not allowed to leave the room" is also a valid construction, it lacks the contraction that makes the original sentence feel more conversational, as well as the nuances conveyed in the original phrasing. Lastly, "We are not allowed to leave the room" shifts the timeframe to the present rather than reflecting the circumstances of the past situation described in the original statement. Thus, the option that best captures and conveys the intended meaning is the one that uses the contraction.
