premise: The Battle of Maldon is the name given to an Old English poem of uncertain date celebrating the real Battle of Maldon of 991, at which the Anglo-Saxons failed to prevent a Viking invasion. Only 325 lines of the poem are extant; both the beginning and the ending are lost.
hypothesis: The middle part of The Battleof Maldon is missing.
reason: This statement is definitely incorrect because the passage states that only the beginning and the end are lost, so the middle of the poem still exists.
