Final answer:
The cause that best completes the cause and effect table is that baby boomers needed more consumer goods than the generation of children that came before them.
Step-by-step explanation:
The cause that best completes the cause and effect table is A. Baby boomers needed more consumer goods than the generation of children that came before them. This is because the baby boomers, who were born between 1946 and 1964, were a more privileged generation and had their own spending power. They had a desire for more consumer goods, which led to advertisers marketing directly to them, rather than their parents.
