1. 结合该节日的设定规则：“Make-A-Difference Day”为每年10月的第四个周六，推算可知符合条件的日期是10月28日，对应选A。
2. 词义猜测题：结合文中语境，此处的“project”指代志愿者策划开展的公益互助相关活动安排，对应中文含义为“方案”，选D。
3. 细节理解题：该节日的核心意义是号召大众帮助他人，是邻里之间互相帮扶的庆祝日；A选项仅提及帮助父母过于片面，C选项是该节日的举办日期而非意义，D选项表述明显错误，因此选B。
4. 细节理解题：该节日倡导大家做力所能及的互助小事，在自己家洗衣服属于普通日常家务，不属于该节日号召大家参与的互助类活动，其余三项的行为都属于该节日相关的活动范畴，因此选A。
5. 细节理解题：原文明确说明在这个节日不需要刻意做重大的事来帮助他人，力所能及的小事就符合节日要求，因此A选项“你应该在当天做大事来帮助他人”的表述是错误的，符合题干选不正确项的要求，选A。
