Question: In a concise analytical response, explain what the source permits—and does not permit—you to conclude about choosing a training dev set size.

Sample answer: The source permits using most of the dev set size guidelines from Chapters 5–7 when choosing the training dev set size. However, it does not claim that every guideline applies, because it deliberately says “most.” Thus, the training dev set should generally follow the earlier sizing guidance without treating its applicability as absolute.

Key points:

• The relevant earlier guidance concerns picking dev set size.
• Most of that guidance also applies to the training dev set.
• The statement does not assert that every guideline applies.
• No additional sizing rule is supplied by the cited evidence.

Rubric: A strong response identifies the earlier dev set guidance, explains its general applicability to the training dev set, and distinguishes “most” from “all” without adding unsupported sizing rules.
