An HR adviser at a logistics company answers about 30 questions a week from line managers about leave and absence rules. Every answer must follow the 120-page staff handbook and use a plain, neutral tone for managers who are not HR specialists. The handbook is reissued each quarter with changes. Which TWO actions should the adviser take? Select TWO.

ACreate a Project whose instructions set the plain, neutral tone and whose knowledge holds the handbook Correct
BPaste the full handbook text at the start of each new chat so every answer starts from the same rules
CWhen the handbook is reissued, replace the old file in project knowledge with the new version Correct
DPaste the whole handbook into the project instructions so Claude reads every rule before answering
EKeep each quarter's handbook in project knowledge side by side so Claude can see how rules changed

For recurring work, put behaviour in project instructions, reference documents in project knowledge, and replace outdated knowledge files rather than adding contradicting versions. A Project separates how Claude should behave (instructions) from what it should draw on (knowledge), and both persist across every chat in the Project. That suits a steady stream of similar questions answered against one document. Because the handbook changes quarterly, accuracy depends on knowledge holding only the current version, since two conflicting files give Claude two answers to choose from.

Why A is correct: This is the recurring, high-volume work a Project is designed for: the instructions carry how Claude should write for every answer, and the handbook sits in project knowledge as the reference material Claude draws on in each chat.

Why B is wrong: It is tempting because it does put the rules in front of Claude. With 30 questions a week it repeats the same setup every time and invites mistakes when an older copy is pasted, which is the problem a Project removes.

Why C is correct: The quarterly reissue is the deciding fact. Swapping the outdated file for the current one keeps a single source of truth, so Claude cannot draw on a superseded rule when answering a manager.

Why D is wrong: It sounds thorough to put the rules where Claude always sees them. Instructions are for behaviour such as tone, audience and format; a long reference document belongs in project knowledge, and cramming it into instructions buries the tone guidance.

Why E is wrong: Keeping history feels careful. Leaving contradictory versions together means Claude may quote a withdrawn rule to a manager; the outdated file should be replaced, with any history kept outside the Project.
