BU Center for the Assessment of Sign Language Interpretation (CASLI) Practice Test

The main idea here is how much an interpreter expands on the message beyond what is actually signed. When the interpreter adds details, explanations, or inferences that aren’t in the source, the interpretation becomes too expansive and can drift from the original meaning. That over-expansion is described as too liberal, because it liberalizes the message by including extra content.

So, the best choice is the one that characterizes adding too much expansion and additions as too liberal. The opposite would be too conservative—omitting or narrowing information—while a balanced rendering would stay faithful to the source without unnecessary additions. Restricted isn’t the standard label for this issue, since it implies limiting content rather than expanding it.
