Final answer:
The term you may come across is 'monograph,' which is a detailed written study of a single specialized subject. 'Manuscript,' 'digest,' and 'anthology' are incorrect in this context.
Step-by-step explanation:
You may come across the term monograph, which is a type of book that focuses on one (mono) topic. The options provided are manuscript, monograph, digest, and anthology. A manuscript is a document written by hand, often lavishly decorated, especially during the Middle Ages. Notable examples of manuscripts include the Christian Bible and Islamic Qur'an. However, the correct answer here is monograph, which is a detailed written study of a single specialized subject or an aspect of it. Unlike manuscripts, which might encompass various topics and could be the creative product of their time, monographs are typically modern, focused texts.
