although表前后转折，前面是liable to change,那么后面就是not change.
后面的句子中does not和unable双重否定，后面空格须表达not change的意思，即constant意思。
在这里selective更贴切。

se·lec·tive    adj.
1 : of, relating to, or characterized by selection : selecting or tending to select
2 : highly specific in activity or effect <selective pesticides> <selective absorption>
