Dear UE's teachers !
Today I meet an uncomprehensible question when i do my English multiple-choices exercises.
And here is it:
Just in case our primary plan fails to succeed, I suggest we have an alternative plan_____
a/ at place
b/ in place
c/ on place
d/ by place
The answer is B: In place. I don't understand what it means and about the other answers.
Can i have more than 1 question? :) Does it (In place) mean the same as "In / Under (any) circumstances".
I'm very grateful for our help!
P/s: Sorry for my bad English!
