Answer:
Gore Corp. is depreciating over a longer term than Ross Corp. This means that on a yearly basis, they will have less depreciation expenses. This would give them a higher net income than Ross Corp but as a result they will then have to pay a higher tax.
Ross Corp on the other hand will be depreciating over a shorter term so this would mean that they are recognizing a higher depreciation expense per year. This would mean that their net income will be lower and by extension their taxes will be lower as well.
