Now since the assessment of intelligence is a comparative matter，we must be sure that the scale with which we are comparing our subjects provides a“valid”or“fair”comparison.

参考答案：

要点:句子的主干是we must be sure…。since引导原因状语从句the assessment of intelligence is a comparative matter。主句中又有that引导的宾语从句that the scale with which we are comparing our subjects provides a“valid”or“fair”comparison。此宾语从句中又套嵌一个由介词with+which引导的定语从句with which we are comparing our subjects修饰先行词the scale。scale在此处意为“尺度、衡量标准”。
译文：既然对智力的评估相比较而言的，那么我们必须确保，在对我们的对象进行比较时，我们所用的尺度能够提供“有效的”或“公平的”比较。
