The short answer works with answers without format and if you like to evaluate if the answer has bold text or its contained in a table it results impossible to achieve.
The text processor question types focuses in these aspects of the answer.
There is an answer helper in a form of a prefilled text in order to narrow the answer and prevent other kind of errors.
The answer dynamic differs from the short answer in which every area answer evaluates one thing , now each area evaluates only one thing and if you want to evaluate let say three aspects, you must fill three answers pointin what you want to assess.
