Answer from cs61c-al (Phillip Chin 16156822) for Question 1
Arrays and pointers seem unaltered during translation. It seems you can access arrays with operations such as lw (load word). Because arrays can be quite large you can access, so it would be better if they are left alone and accessed when needed using the name of the array, otherwise memory spilling could occur. Pointers are essentially the array name and are needed for lookup.
