Input: Read this: In 2007 Torsten Struck and colleagues compared 3 genes in 81 taxa, of which 9 were outgroups, in other words not considered closely related to annelids but included to give an indication of where the organisms under study are placed on the larger tree of life. For a cross-check the study used an analysis of 11 genes (including the original 3) in 10 taxa. This analysis agreed that clitellates, pogonophorans and echiurans were on various branches of the polychaete family tree. It also concluded that the classification of polychaetes into Scolecida, Canalipalpata and Aciculata was useless, as the members of these alleged groups were scattered all over the family tree derived from comparing the 81 taxa. In addition, it also placed sipunculans, generally regarded at the time as a separate phylum, on another branch of the polychaete tree, and concluded that leeches were a sub-group of oligochaetes rather than their sister-group among the clitellates. Rouse accepted the analyses based on molecular phylogenetics, and their main conclusions are now the scientific consensus, although the details of the annelid family tree remain uncertain.
Question: Who compared annelid genes in 1807?

Output: unanswerable


Input: Read this: In 1978 Aboriginal writer Kevin Gilbert received the National Book Council award for his book Living Black: Blacks Talk to Kevin Gilbert, a collection of Aboriginal people's stories, and in 1998 was awarded (but refused to accept) the Human Rights Award for Literature for Inside Black Australia, a poetry anthology and exhibition of Aboriginal photography. In contrast to previous definitions based solely on the degree of Aboriginal ancestry, in 1990 the Government changed the legal definition of Aboriginal to include any:
Question: What year was Gilbert awarded for his efforts?

Output: 1978


Input: Read this: The textual critic's ultimate objective is the production of a "critical edition".[citation needed] This contains the text that the author has determined most closely approximates the original, and is accompanied by an apparatus criticus or critical apparatus. The critical apparatus presents the author's work in three parts: first, a list or description of the evidence that the editor used (names of manuscripts, or abbreviations called sigla); second, the editor's analysis of that evidence (sometimes a simple likelihood rating),[citation needed]; and third, a record of rejected variants of the text (often in order of preference).[citation needed]
Question: How many parts is in the textual apparatus?

Output: unanswerable


Input: Read this: Each play constitutes a down. The offence must advance the ball at least ten yards towards the opponents' goal line within three downs or forfeit the ball to their opponents. Once ten yards have been gained the offence gains a new set of three downs (rather than the four downs given in American football). Downs do not accumulate. If the offensive team completes 10 yards on their first play, they lose the other two downs and are granted another set of three. If a team fails to gain ten yards in two downs they usually punt the ball on third down or try to kick a field goal (see below), depending on their position on the field. The team may, however use its third down in an attempt to advance the ball and gain a cumulative 10 yards.
Question: What does a team do in their position on the field when they haven't advanced the ball enough to score?

Output:
unanswerable
