Ray Kroc was the food critic that pushed McDonald to what it is today. Walt Disney was from a broken home until he created Disney and even today, it is a great billion dollar company. Disney was born in Chicago, so answer A would be incorrect. C would be incorrect also because Walt Disney was raised in poverty rated homes. The answer, one I cannot give you because you should need to complete it yourself, should either be D or B.
No it is no a slang , it is not that informal.
It's definitely between C and D, although I'm leaning towards C.
Keep a firm grip on the steering wheel and do not break!
