F5 exams question answering

Hi John, please i am finding it hard defining accounting terminology like responsibility accounting. I understand it very well so can I explain it with an example such as; with responsibility accounting, if a production manager whose focus is on quality receives adverse production variance( especially material price) but produces quality products that enables the sales manager to receive both favourable sale price and volume variance. in this case, the sales manager will be congratulated but the production will be on a hot seat.So my question is, is it ok to explain accounting concepts with examples like the one above and gain full marks or do we have to memorize book definitions. Thank you
