Multiple Choice

In the Semicircle Test, if the bay is smaller than the corresponding semicircle, what can be done?

The semicircle test helps decide whether a bay can be enclosed by straight baselines across its mouth. If you draw a semicircle with its diameter equal to the distance across the bay’s mouth, and the bay lies entirely within that semicircle, the bay is considered small enough to be included behind a straight baseline. In that case, the baseline can be drawn across the bay’s mouth, so the bay becomes part of the nation’s territorial waters behind that baseline. This is why including the bay within the baseline is the correct outcome when the bay is smaller than the semicircle. The other options describe actions you’d take if the bay were large relative to the semicircle, not when it is small.
