Final answer:
Collingham dismisses the critics' complaint by explaining that many individuals from Bangladesh have migrated to India and opened restaurants, bringing their culinary traditions with them.
Step-by-step explanation:
Collingham dismisses the critics' complaint that most owners of Indian restaurants are actually from Bangladesh because the critics' complaint is not based on accurate information. Collingham argues that the critics are making assumptions and generalizations without considering the individual circumstances of the restaurant owners. She explains that many individuals from Bangladesh have migrated to India and opened restaurants, and they bring their culinary traditions with them. Therefore, it is misleading to claim that most Indian restaurant owners should be from India.
