The correct answer to this open question is the following.
Although there are no options attached, we can say the following.
The economic questions that are not covered in Mark's scenario could be the following.
Mark needs to ask about what its competitors might be. Direct and indirect competitors in the zone. He has to know the kind of products they are selling, their prices, offers, and promotions, so he can make business decisions.
Another question he is missing is his business plan. He needs a full business plan so he can consider all aspects and variables during the opening and the firsts years. He also needs to ask himself if he has enough resources to outlast the competitors.
One's motivations and emotions are controlled by the forebrain.
Thus,
among the four choices above, the answer is none other than a. forebrain
Forebrain is the anterior part of the brain. There is what we call the hypothalamus that also controls emotions. Love has to be credited to this part.
For example:
"I love you with all my heart."
The heart does not feel emotions, the hypothalamus does. So instead of heart we replace it with,
"I love you with all my hypothalamus"
