理想实验有时更能反映自然规律,伽利略设想了一个理想实验,如图所示,其中一个是经验事实,其余是推论。(1)减小第二个斜面的倾角,小球在这个斜面上仍然要达到原来的高度;(2)两个对接的斜面,让静止的小球沿一个斜面滚下,小球将滚上另一个斜面;(3)如果没有摩擦,小球将上升到原来释放的高度;(4)继续减小第二个斜面的倾角,最后使它成水平面,小球将沿水平面做持续匀速运动。

(1)请将上述理想实验的设想步骤按正确的顺序排列____________(只要填写序号即可);

(2)在上述设想步骤中,有的属于可靠事实,有的则是理想化推论,下列关于推论和事实的分类正确韵是____________。

A.(1)是事实,(2)(3)(4)是推论

B.(2)是事实,(1)(3)(4)是推论
