Final answer:
A chapter's Shamrock fundraiser benefits a local organization that typically supports children's health or community welfare, with the chosen organization varying by location.
Step-by-step explanation:
The specific local organization benefited by a chapter's Shamrock fundraiser will vary depending on the chapter's location and chosen beneficiary. Usually, these fundraisers are organized to support causes related to children's health or community welfare.
The chapter may partner with a local charity, hospital, or another non-profit organization dedicated to improving the lives of those in need. In some cases, the beneficiaries of Shamrock fundraisers are tied to national campaigns or charities that focus on specific diseases or support services but the funds raised locally are often used within the community.
