Fill in the blank question with partial matching of student's answer

Is it possible to have a question whose answer string only has to partially match the answers in the list of the correct answers?


For example:

        What type of voltage probe has the highest impedance: active probes or passive probes?

An acceptable answer would start with "aktiva" or "acti" (depending on whether the student answers in Swedish or English), but would not have the substring "passiv" in it (either the Swedish "passiv" or English "passive"). Logically the correct answer could be expressed as a partial match: ("aktiva"|"acti")&!"passiv"'


I realize that the above question could be turned into a multiple choice quiz question, but have simply used it as an example of where a partial string match can be used. [Logically this is similar to the concept of exactness in a numeric answer.]
