【正确答案】根据材料可知，佳宝公司洗碗机的市场增长率为9%，小于10%，属于低速增长。相对市场占有率为30%÷15%=2，大于1。因此可以判断洗碗机属于现金牛业务。消毒柜的市场增长率为20%，大于10%，属于高速增长，相对市场占有率为30%÷20%=1.5，大于1，因此可以判断消毒柜属于明星业务。 电烤箱的市场增长率为4%，小于10%，属于低速增长，相对市场占有率为8%÷40%=0.2，小于1，因此可以判断电烤箱属于问题业务。

【正确答案】洗碗机属于现金牛业务，对这一象限内的大多数业务，市场增长率的下跌已成不可阻挡之势，因此可以采用收获战略。消毒柜属于明星业务，适宜采用的战略是积极扩大经济规模和市场机会，以长远利益为目标，提高市场占有率，加强竞争地位。电烤箱属于问题业务，对问题业务应采取选择性投资战略。 English answers: (1)According to the material, the growth rate of Jia Bao's dish washer is 9%, which is lower than 10% and is a low growth.
