Final answer:
Mrs. Beatty has Henry sell Keiko's presents.
Step-by-step explanation:
In the book 'Hotel on the Corner of Bitter and Sweet' by Jamie Ford, Mrs. Beatty, who is Henry's mother, does not throw away or dip Keiko's presents in rice. Instead, she has Henry sell them to his classmates for a small profit. This is done to hide Keiko's identity as a Japanese American during a time of prejudice and discrimination against Japanese people in America during World War II.
