Answer:
The order of questions most objetive and unbiased is first (a) and then (b)
Explanation:
The order of the questions influences the answer of the people. If you ask first about dating, when they answer the question about happiness, the second answer would focus on the happiness it brings if they are datting. That means that I am inducing an answer about the happines of being dating or not, that is not ethical and the survey is not objetive. If the order of the questions is first (a) and the (b), the answer about happiness is not focused in the sentimental situation, and you can find if there is a correlation betwen the happiness and dating.
