試題4

For the technical writer, the paste-pot is as mighty as the pen.
Since this is so, and since tomorrow's product-quality manuals will grow from today’s memos, it is very important to get the structure of the documentation right. The early design of the project （） ensures that the documentation structure itself is crafted, not haphazard. Moreover, the establishment of a structure molds later writing into segments that fit into that structure.

A.structure
B.specification
C.standard
D.objective
