Straight from the study design. Had it on my SAC but definitely got it wrong
"discuss the implications of changes in the level of debt ratio"
I would say something on the lines of:
Debt ratio measures the percentage of assets funded by external sources of finance (liabilities). The higher the debt ratio, the more reliant a firm is on external sources to fund assets. This can have implications to the firm's risk taking as more reliance on external sources would mean less reliant on owner's investment, and thus a greater return for every dollar invested by the owner. Hence, a greater debt ratio equals more risk but also more reward for the owner. On the other hand, a low debt ratio would indicate a low reliance on external sources to fund assets and thus more reliance on owner's investment, however a smaller return per dollar invested would be expected. Thus, low debt ratio equals low risk and also low return. It is important for the business owner to find a good balance between the amount funded by their pocket, and the amount funded by external sources so that the amount of risk is minimalised however not affecting a return on their investment
