为探究“废电池对生物的影响”，某研究小组设计了如下实验步骤：
①将一节用过的五号电池破碎，浸泡在1000mL清水中3天，过滤得到滤液。②四只鱼缸分别贴上A、B、C、D标签，并在鱼缸中都加入5000mL清洁无污染的河水。③在A、B、C、D四只鱼缸中，依次加入50mL、100mL、200mL、400mL的电池浸出液。④再向各鱼缸中分别加入三条大小和生活状态差不多的小金鱼，定时喂等量同种饲料，观察并记录情况。

结果如下表： 

                      A    B    C    D
所加浸出液的体积(mL)  50  100  200  400
小鱼存活的时间(天)    15   12   7    1
根据以上设计，请回答下列问题：

（1）该小组同学提出的问题是：__________________________________________________。

（2）根据表中的数据可知，水中电池浸出液的浓度越大，金鱼存活的时间就越_______。

（3）由此，该小组同学得出结论：废电池对生物有影响。你认为他们这样得出结论严谨？
答：__________。为什么？_________________________________________。

（4）请你对使用过的电池如何处理作出合理化的建议：_______________________。
