### Instruction: help me answer this question If A = {1, 2, 3, 4}, B = {3, 4, 5, 6}, C = {5, 6, 7, 8} and D = {7, 8, 9, 10}; find (i) A ∪ B (ii) A ∪ C (iii) B ∪ C (iv) B ∪ D (v) A ∪ B ∪ C (vi) A ∪ B ∪ D (vii) B ∪ C ∪ D, think step by step
### Assistant:  , The answer is {'i': 'A ∪ B = {1, 2, 3, 4, 5, 6}', 'ii': 'A ∪ C = {1, 2, 3, 4, 5, 6, 7, 8}', 'iii': 'B ∪ C = {3, 4, 5, 6, 7, 8}', 'iv': 'B ∪ D = {3, 4, 5, 6, 7, 8, 9, 10}', 'v': 'A ∪ B ∪ C = {1, 2, 3, 4, 5, 6, 7, 8}', 'vi': 'A ∪ B ∪ D = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}', 'vii': 'B ∪ C ∪ D = {3, 4, 5, 6, 7, 8, 9, 10}'}
