Does anyone can help me to solve this questions? Thank you so much!

1. Inventory consists of three sub-accounts. Please name all of them for a manufacturing firm.

2. What is material requisition form? What is its function? What is time ticket? Why it is useful?

3. The textbook tells us that, during an inventory audit, the extent & timing of tests related to ending inventory can be reduced or altered, if the client has an accurate/well-controlled perpetual (inventory) system. Please explain the meaning of this sentence to the professor.
