Input: Read this: According to Y chromosome studies by Sanchez et al. (2005), Cruciani et al. (2004, 2007), the Somalis are paternally closely related to other Afro-Asiatic-speaking groups in Northeast Africa. Besides comprising the majority of the Y-DNA in Somalis, the E1b1b1a (formerly E3b1a) haplogroup also makes up a significant proportion of the paternal DNA of Ethiopians, Sudanese, Egyptians, Berbers, North African Arabs, as well as many Mediterranean populations. Sanchez et al. (2005) observed the M78 subclade of E1b1b in about 77% of their Somali male samples. According to Cruciani et al. (2007), the presence of this subhaplogroup in the Horn region may represent the traces of an ancient migration from Egypt/Libya. After haplogroup E1b1b, the second most frequently occurring Y-DNA haplogroup among Somalis is the West Asian haplogroup T (M70). It is observed in slightly more than 10% of Somali males. Haplogroup T, like haplogroup E1b1b, is also typically found among populations of Northeast Africa, North Africa, the Near East and the Mediterranean.
Question: What percentage of Somali males had DNA containing the M78 subclade of E1b1b?

Output: 77%

Input: Read this: Old English nouns had grammatical gender, a feature absent in modern English, which uses only natural gender. For example, the words sunne ("sun"), mona ("moon") and wif ("woman/wife") were respectively feminine, masculine and neuter; this is reflected, among other things, in the form of the definite article used with these nouns: seo sunne ("the sun"), se mona ("the moon"), t wif ("the woman/wife"). Pronoun usage could reflect either natural or grammatical gender, when those conflicted (as in the case of wif, a neuter noun referring to a female person).
Question: what did not have a gender in Old English?

Output: unanswerable

Input: Read this: On the field at the beginning of a play are two teams of 12 (unlike 11 in American football). The team in possession of the ball is the offence and the team defending is referred to as the defence. Play begins with a backwards pass through the legs (the snap) by a member of the offensive team, to another member of the offensive team. This is usually the quarterback or punter, but a "direct snap" to a running back is also not uncommon. If the quarterback or punter receives the ball, he may then do any of the following:
Question: What is the term for the team who begins a play with control of the ball?
