Morphology
Friedman + test
This is an eponymous phrase combining a surname 'Friedman' (which carries no lexical meaning) with the generic noun 'test', so a learner who knows the words would at best infer 'a test associated with Friedman' but not its nature. The specific procedure and meaning (injecting urine into a rabbit to detect pregnancy) are not deducible from the constituents, making the expression opaque to B1 learners.
Etymology
Friedman test was an old medical test where doctors put a woman's urine into a female rabbit that had not mated and then looked for changes in the rabbit's ovaries. So, if the rabbit showed a change, it told doctors the woman was probably 'pregnant'.
