Which of these is NOT typically associated with Memorial Day?

Memorial Day is a federal holiday in the United States observed for honoring and mourning the military personnel who have died in the performance of their military duties. The observances associated with Memorial Day typically include activities such as decorating graves, which involves placing flowers or flags on the graves of fallen soldiers, and official ceremonies, such as memorial services or parades that recognize and honor those who have served and sacrificed for the country.

While picnics are a common activity that many people engage in during the long weekend, reflecting a more general celebration of the unofficial start of summer, they are not reflective of the holiday's solemn purpose. The focus of Memorial Day is primarily on remembrance, so gatherings for leisure, such as picnics, are not associated with the underlying meaning of the day.

Labor rallies, on the other hand, are more closely associated with Labor Day, which celebrates the contributions of workers and the labor movement. This makes them entirely distinct from Memorial Day, which is dedicated to remembering military personnel and honoring their sacrifice. Thus, the correct answer highlights the activity that is unrelated to the solemn observance of Memorial Day.
