You will be presented with a citation segment from the section of an NLP research paper, as well as the context surrounding that citation. Classify the intent behind this citation by choosing from one of the following categories:
- Background: provides context or foundational information related to the topic.
- Extends: builds upon the cited work.
- Uses: applies the methods or findings of the cited work.
- Motivation: cites the work as inspiration or rationale for the research.
- CompareOrContrast: compares or contrasts the cited work with others.
- FutureWork: cites the work as a direction for future research.

Your answer should be a single word from the following list of options: ["Background", "Extends", "Uses", "Motivation", "CompareOrContrast", "FutureWork"]. Do not include any other text in your response.

Section Title:
introduction

Context before the citation:
It would seem therefore that the iteration of the PT operation to form a closure is needed (cfXXX Zadrozny 1987b).  This immediate information may be insufficient to decide the truth of certain predicates. The partial theories pick up from the referential level the most obvious or the most important information about a formula.

Citation Sentence:
It would seem therefore that the iteration of the PT operation to form a closure is needed ( cfXXX Zadrozny 1987b ) .

Context after the citation:
However, there are at least three arguments against iterating PT. First of all, iteration would increase the complexity of building a model of a paragraph; infinite iteration would almost certainly make impossible such a construction in real time. Secondly, the cooperative principle of Grice (1975, 1978), under the assumption that referential levels of a writer and a reader are quite similar, implies that the writer should structure the text in a way that makes the construction of his intended model easy for the reader; and this seems to imply that he should appeal only to the most direct knowledge of the reader. Finally, it has been shown by Groesser (1981) that the ratio of derived to explicit information necessary for understanding a piece of text is about 8:1; furthermore, our reading of the analysis of five paragraphs by Crothers (1979) strongly suggests that only the most direct or obvious inferences are being made in the process of building a model or constructing a theory of a paragraph.
