Question

During the economic downturns of 2008 and 2009, many US restaurant companies struggled to avoid heavy losses. However, some still managed to outperform the market and even made large profits in the midst of widespread economic difficulties. McDonald's was one such company..."(Yoon et al, 2013)

Answer 1

If you are asking/wondering if this affected their business(ess) then I would have to say yes. I said yes because it says "Many US restaurant companies struggled to avoid heavy losses." (key word(s) is/are Avoid and Struggled to) which means some of them, including McDonalds probably did avoid this and some other McDonald's didn't avoid this.
