Final answer:
Two truths about financial ratios are that they help assess financial performance and are not only useful for large corporations. They provide comparative measures rather than absolute values and are influenced by industry norms.
Step-by-step explanation:
The question is regarding the truthfulness of certain statements about financial ratios. Financial ratios do not provide absolute values; instead, they offer comparative measures that help analyze a company's financial performance relative to its past performance, industry benchmarks, or competitors. Thus, answer A) is incorrect. Financial ratios are indeed powerful tools that help assess financial performance, so answer B) is correct.
They are not exclusively useful for large corporations, as even small and medium-sized enterprises can use financial ratios for analysis and decision-making, thereby making statement C) incorrect. Finally, financial ratios are influenced by industry norms, and analysts often compare a company's ratios against industry averages to determine relative performance, making answer D) incorrect.
