I came across this sentence:
background - the character Rick was kidnapped by a bad guy and then there is this dialogue
Well... Let's get everybody to the hangar.We'll warm up the quinjet and try a trace signal on Rick's physiological
And I can't understand the prepositions in this sentence. First, why try a trace signal. As far as I've seen they usually say:
try to trace signal.
and I also don't understand the preposition on:
a trace signal on Rick's physiological
Isn't it correct to use of together with signal?
a trace signal of Rick's physiological
Or does on refer to not signal ? I hope the question is not too silly ,I would be happy to help.
