5lb Manhattan Prep 2nd Ed, p. 129 , #81

Hello,
The answers for #81 were impervious and inimical, although I was confused with the choice of inimical because I thought it meant hostile or unfriendly instead of "not likely to change." I tried looking up different definitions and usages of inimical online, but I can't seem to find one that was like impervious. Is this definition of inimical more of an implicit definition or is this an error?

Thanks! (Also sorry if this was already brought up, although I couldn't find it in the forum.)

I agree. This question doesn't work. I'll look into it.
