I'm having a hard time understanding what the heck this question is about. It's just such a weird wording.
It's Q.22 from the first LR section(sec.2), Feb. 2000. Is there a conditional reasoning involved? or do you just get it?
I figured it as a conditional reasoning. something like,
being at home -> ~being in the house (first sentence)
being in the house -> ~being at home (second sentence)
being in the house -> ~being at home (conclusion, third sentence)
So, I put (C) and got it right. but I'm not confident if I did it the right way.
Hope somebody can help me...
I always appreciate your help.
