14. A computing device comprising: a communication interface; a processor; and a non-transitory computer-readable medium having stored thereon program instructions that when executed by the processor cause the computing device to perform a set of acts, the set of acts comprising: accessing first data representing text, wherein the text defines at least two grammatical break positions representing a particular type of grammatical break between two portions of the text; identifying, from among the at least two grammatical break positions, a position that is closest to a target position within the text, wherein the target position is within a range from a first position to a second position, wherein the first position is positioned after 100 words from a beginning of the text, and wherein the second position is positioned before 130 words from the beginning of the text; based on the identified position within the text, generating second data that represents a proper subset of the text, wherein the proper subset extends from an initial position within the text to the identified position within the text; and providing output based on the generated second data.
