The likelihood of the new laboratory being ready for the start of the term is described as?

The likelihood of the new laboratory being ready for the start of the term being described as "slim" indicates a low probability of completion. This term conveys a sense of doubt or skepticism about whether the laboratory will be ready in time. Choosing "slim" emphasizes the challenges or obstacles that may prevent the laboratory from being operational as initially hoped.

In this context, "promising" would suggest a more optimistic view, indicating a higher chance of readiness, which contradicts the intended meaning. Similarly, "uncertain" implies variability in the outcome, but does not strongly convey the low chances as effectively as "slim." The term "high" presents a positive outlook regarding readiness, which diverges from the implication of significant doubt bequeathed by "slim." Hence, the choice of "slim" appropriately captures the essence of skepticism concerning the laboratory's readiness by the start of the term.
