The most likely reasons Nina decides not to buy the product made in another country could include:
- She wants a hair product that is less expensive and safer to use.
- She wants to find out whether the company respects workers’ rights.
- She wants to find out if a similar product is made in the United States.
These reasons reflect considerations about cost, safety, ethical implications, and preference for domestic products. The option about wanting to know if her friend is going to buy the product is less likely to be a reason for her decision.
