Answer: The real answer is Mawu
Explanation: In Dahomey (West African) mythology, Mawu is a creator goddess, associated with the sun and moon. After creating the earth and all life and everything else on it, Mawu became concerned that it might be too heavy, so she asked the primeval serpent, Aido Hwedo, to curl up beneath the earth and hold it up in the sky.
This could be caused by one of three things: (1) Your tree is growing more leaves than it can support, (2) pests and diseases infect the leaves, or (3) your tree might be getting too much or too little water.
Ok, so technically, you have to answer if you think that Martys parents suspect if hes keeping the dog, if your answer is No or Yes you write it, then you go back to the book and write from the book whatever it is that supports your answer. then after that you have to explain if you think hes doing a good job hiding the dog.
hope i kind of helped :)
