Step-by-step explanation:
Target was interested in identifying pregnant shoppers primarily because of their habits. Pregnancy is a crucial time when consumers often develop new buying habits, and businesses like Target aim to cater to their needs early on, with the hope that the shoppers will become long-term customers.
