Definition: Compose a new way to ask the same question. The new question must be asking the exact same thing as the original question does. Without any other information, you should be able to tell that the original question and the new question are the same. Preserve bracketed phrases in your new question. You can change the rest of the question provided the above requirements are satisfied. The new question must have a natural, fluent formulation, as if it were composed by a native English speaker. You will be given three pieces of information to help you create better questions. Those are: "Answer": the answer to the question, e.g., "Honolulu". "Answer Type": the type of the answer, e.g., "Location". "Auxiliary Information" is a detailed description of some concepts mentioned in the question, if any.
Input: original question: What type of lake is the lake which has the island [Isola Comacina]?
answer: glacial lake
answer type: Lake type.
auxiliary information: Isola Comacina is a small wooded island of Italy‚Äôs Lake Como, administratively a part of the commune of Ossuccio. It is located close to the western shore of the Como arm of the lake in front of a gulf known as Zoca de l'oli, a Lombard name referring to the local small-scale production of olive oil. In the late 6th century the island was a remaining Roman stronghold under Francio, a subordinate of Narses; though the areas surrounding Lake Como were entirely controlled by the Lombards. The island was besieged for a good deal of time by the Lombards under Authari who released Francio to flee back to Narses' capital at Ravenna. The Lombards found the island to contain "many riches" deposited for safekeeping by local Roman loyalists. In 1919 the island was given to Belgium, in homage to King Albert I. The island was returned the following year. The island now consists of a restaurant, cafe, and collection of archaeological sites.

The lake containing the island [Isola Comacina] is what type of lake?
