Task: Question Answering
Input (English): passage: An exclave is a portion of a state or territory geographically separated from the main part by surrounding alien territory (of one or more states). Many exclaves are also enclaves. Enclave is sometimes used improperly to denote a territory that is only partly surrounded by another state. Vatican City and San Marino, enclaved by Italy, and Lesotho, enclaved by South Africa, are the only completely enclaved states. Unlike an enclave, an exclave can be surrounded by several states. The Azerbaijani exclave of Nakhchivan is an example of an exclave.
 question: is lesotho the only country within a country?
Output (English): No
