would you recommend that accountants wait until collections are made from customers before recording sales revenue

No

Explanation:

Accounting currently uses the Accrual basis and this is the best basis to use so far because it records revenue when they are earned not when the actual money comes in.

In doing this, the company is able to properly ascertain the revenue that it made in a particular period. If a company were to wait until collections were made, the company might wait for over one period to record their sales which would not be very helpful in calculating income for the period.

Also if companies waited to record only after sales, people not paying and becoming doubtful debts become a headache to record.

metallurgy is your answer

the "study of metals and the process of refining ("

note that it says metal. metallurgy has the word "metal" in it, and so is most likely your answer (and is your answer).
